Species lost since 2013 - None. Data Analysis Watershed - Drains the northwestern corner of Ashe County and a small part of Virginia along the Tennessee border. This site is about 1.2 miles upstream from the confluence with the North Fork New River. Habitats - Fairly open canopy here with riparian vegetation of mostly shrubs and grasses, and few shade trees on the banks. A few vertical, eroding banks within the sample reach, one with stacked concrete armoring. Instream habitats are primarily embedded runs, decent pools, and infrequent riffles with Podostemum covered rocks. No apparent habitat changes have occurred here since the last assessment. 2018 fish community - An extremely diverse assemblage of fish was collected in 2018, with all 24 species known from this location, and great abundance (n=560 vs. 339 in 2013). Eight of the 24 taxa collected in 2018 are considered pollution intolerant species [Rock Bass (n=23), Smallmouth Bass (n=2), Tonguetied Minnow (n=12, state listed - Significantly Rare), Silver Shiner (n=1), New River Shiner (n=13), Kanawha Rosyface Shiner (n=1, state listed - Significantly Rare), Kanawha Minnow (n=2, state listed - Special Concern), and Kanawha Darter (n=6, state listed - Significantly Rare)]. Four stocked Brown Trout, ranging from 237 - 461 mm TL, and two stocked Rainbow Trout at 304, and 350 mm TL were also collected and released (site is managed as NCWRC Delayed Harvest Waters). Blackspot (larval parasite, common, and relatively harmless to freshwater fish) was observed in at least three species (Saffron Shiner, Bigmouth Chub, and Bluehead Chub). Species with young-of-year present in 2018 include Northern Hogsucker (n=4), Rock Bass (n=2), Saffron Shiner (n=1), Bluehead Chub (n=21), Tounguetied Minnow (n=3), Central Stoneroller (n=17), Mottled Sculpin (n=2), Redbreast Sunfish (n=1, no other cohorts), White Sucker (n=3), and Mountain Redbelly Dace (n=1). 1998-2018 - Despite lower habitat scores and slightly elevated specific conductance at this location, the fish community continues to thrive in this mostly forested catchment. The 2018 assessment resulted in the highest NCIBI score here to date, and the site's first fish community rating of Excellent.

Species lost since 2013 - None. Data Analysis Watershed - Drains most of the northwest corner of Ashe County along the Tennessee border. This site is about 1000 feet upstream from the creek's confluence with the North Fork New River. Habitat - Fairly open canopy here at the NC 88/Big Laurel Road intersection (convenience store located here). Stream banks are vegetated mostly with grasses and shrubs, and few trees. Instream habitats are primarily embedded runs with small side snags, some boulder pools, and infrequent riffles. With little canopy here, most of the sun-exposed rocks are covered with Podostemum. No apparent habitat changes since the 2013 survey. 2018 fish community - A highly diverse and abundant group of fish was collected, including 7 intolerant species [Rock Bass (n=1), Tonguetied Minnow (n=38, state listed - Significantly Rare), New River Shiner (n=12), Kanawha Rosyface Shiner (n=26, state listed - Significantly Rare), Kanawha Minnow (n=2, state listed - Special Concern), Kanawha Darter (n=2, state listed - Significantly Rare), and Appalachia Darter (n=2, state listed - Significantly Rare)]. In contrast, 2 tolerant species were also collected for the first time at this site [Redbreast Sunfish (n=2, non-native insectivore), and Bluntnose Minnow (n=1, omnivore)]. Big Laurel Creek is managed as NCWRC Hatchery Supported Waters; 2 stocked Rainbow Trout were collected and released (304 and 350 mm TL). Species with young-of-year cohorts in 2018 include Mountain Redbelly Dace (n=70), Central Stoneroller (n=6), Brown Trout (n=2), Northern Hogsucker (n=32), Tonguetied Minnow (n=19), Bigmouth Chub (n=4), White Sucker (n=6), Rosyside Dace (n=9), Western Blacknose Dace (n=40), and Fantail Dater (few). One Eastern Hellbender (Cryptobranchus alleganiensis - indicator species of high quality water) was also measured (420 mm) and released. 2008-2018 - Twenty-four fish species are now known from this regional reference site, with 8 intolerant species (including 5 state-listed fish), 12 intermediately tolerant species, and only 4 tolerant species. Despite the slight drop in habitat score in 2018, the fish community rating improved to Excellent for the first time in 4 assessments. According to the historic water quality parameters and fish bioclassifications cataloged here, water quality conditions remain high in this mostly forested mountain catchment.

Species lost since 2013 - Rock Bass (2 collected in 2013), Silver Shiner (1 collected in 2013), and wild Brown Trout (1 collected in 2013). Data Analysis Watershed - Drains the southeast corner of Alleghany County and is a large tributary to the Little River. Site is roughly 7.5 miles upstream of the creek's confluence with the river. Habitat - Thin riparians here separating the surrounding row crops from the stream (little canopy shading as a result). Cobble and gravel substrates are relatively embedded here, with instream habitats of primarily runs with undercuts and side pools, and occasional riffles and chutes. Habitats appear unchanged since the 2013 assessment. 2018 fish community - A diverse fish community was collected in 2018, including 4 intolerant species [Highback Chub (non-native), Kanawha Minnow (state listed - Special Concern), Kanawha Darter (state listed - Significantly Rare), and Appalachia Darter (state listed - Significantly Rare), but no mature bass or wild trout. There was also an 89% increase in total abundance compared to the last survey (n=519 in 2018 vs. 274 in 2013), and a much higher percentage of multiple aged fish (68% in 2018 vs. 39% in 2013). 2018 also marked the first record here for Green Sunfish (n=1, non-native and relatively aggressive sunfish species). Overall, there was no net change in the fish assemblage, according to the 2018 NCIBI. Brush Creek is managed as hatchery supported trout waters; one stocked Brown Trout was collected at 274 mm. Species with young-of-year in 2018 include Northern Hogsucker (n=7), White Sucker (n=1), Brown Trout (n=2, the only wild specimens collected), Mottled Sculpin (n=2), Fantail Darter (n=1), Redlip Shiner (n=3), Mountain Redbelly Dace (n=9), Bluehead Chub (n=10), and Western Blacknose Dace (n=2). 2008-2018 - With the exception of several uncommon species, the fish assemblage in this catchment has remained relatively unchanged at this location, with the same overall NCIBI scores and Good ratings over 3 assessments. Water quality parameters have remained consistent here as well, further indication of stability in the watershed. Most Abundant Sp.Non-Native Sp. 05/05/08 2008-27 19 52 Good Fantail Darter (n=135, 26%), and Redlip Shiner (n=120, 23%).

Species Change Since Last Cycle Species gained since 2013 - Creek Chub (n=1, new record). Species lost since 2013 - White Sucker (1 collected in 2013), and Kanawha Minnow (1 collected in 2013, state listed - Special Concern). Saffron Shiner were collected in 2008 (n=25), but not in 2013 or 2018. Data Analysis Watershed - Drains central Ashe County and is a tributary to the North Fork New River. Site is located about 3.6 miles upstream from the creek's confluence with the river. Habitat - Fairly good riparian (mix of trees, shrubs, and grasses), and canopy shading here, given that the sample reach is bordered for most of it's length by Buffalo Road on the left. Some boulder and rip rap armoring of the steep left bank where the road is nearest to the creek. Instream habitats include swift cobble/boulder riffles and runs, with fast chutes, and boulder pools of various sizes. 2018 fish community - A slight increase in abundance since the 2013 assessment (n=622 in 2018 vs. 521 in 2013), yet the total taxa count decreased by 1 in 2018. The trophic structure also shifted slightly to a higher percentage of insectivores (42% decline in Bluehead Chub, intermediately tolerant omnivore). However, had just 1 specimen of the intolerant Kanawha Minnow been collected again (Phenacobius teretulus , state listed - Special Concern), the 2018 NCIBI score would have retained 2 points, and the site would have rated Good-Fair for a third time. For this reason, and since the overall taxa list (as well as species abundance proportions) remained nearly unchanged, the site is Not Rated for 2018. This site is managed as NCWRC Hatchery Supported Trout Waters, yet only wild specimens of Brown and Rainbow Trout were collected in 2018. Species with young-of-year in 2018 - Brown Trout (n=12), Bluehead Chub (n=1), and Western Blacknose Dace (n=7). 2008-2018 - The slight decline in NCIBI score and change in rating does not accurately reflect the seemingly unchanged water quality in this catchment. Rather, this high gradient, moderately diverse site exists on the margin between Good-Fair and Fair ratings, and may also be on the fringe of ratability with the NCIBI. Overall, these fish community data (and water quality parameters) continue to suggest no substantial changes in water quality in this mostly forested watershed. This site may be resampled to confirm its 2018 rating. Most Abundant Sp.Mottled Sculpin (n=270, 43%), and Fantail Darter (n=218, 35%). Non-Native Sp.

Species lost since 2013 - Tessellated Darter (5 collected in 2013). Data Analysis Watershed - Drains northeastern Alleghany County. This site is about 1.5 miles upstream of the confluence with the Little River. Habitat - Thin riparians and open canopy here, with mostly shrubs, grasses, and few trees along the banks. Only one shady spot within the 600 foot sample reach. Row crops bordering the left bank, and fallow fields on the right. A few vertical, scoured banks located at channel bends. Instream habitats with a mix of habitat types including rocky riffles, runs, pools of various sizes (some larger sandy bottom pools), and a few bedrock chutes. 2018 fish community - A diverse and abundant assemblage was collected in 2018 (n=715) including 5 intolerant species [Rock Bass (n=5), Smallmouth Bass (n=1), Silver Shiner (n=5), Kanawha Rosyface Shiner (n=5, Significantly Rare), and Kanawha Darter (n=8, Significantly Rare)]. However, the herbivorous Central Stoneroller, and omnivorous Bluehead Chub accounted for a combined 70% of the fish community (down from 74% in 2013). A new record in 2018 for Smallmouth Bass (intolerant piscivore) is largely responsible for the improvement in NCIBI score (4 of 6 points) and rating progression to Good. The other improvement was a 23% increase in multiple age groups present. New records in 2018 for White Sucker (n=6) were documented as well. Several species with minor to heavy blackspot (common, relatively harmless larval parasite) but no other disease noted. Species with young-of-year cohorts in 2018 - Margined Madtom (n=3), White Sucker (n=1), Northern Hogsucker (n=7), Bluehead Chub (n=85), Central Stoneroller (n=94), Mountain Redbelly Dace (n=5), Longnose Dace (n=11), Western Blacknose Dace (n=1 at 25 mm, no other cohorts), Largemouth Bass (n=1 at 54 mm, no other cohorts), Appalachia Darter (n=1 at 16 mm, no other cohorts), and Silver Shiner (n=5). 2008-2018 - There are now 23 known species from this site, which continues to be dominated by grazers (Central Stoneroller) and omnivores (Bluehead Chub). Despite the prolonged evidence of non-point nutrient inputs in this watershed, the fish community here suggests biological stability and generally good water quality. Overall, this site has improved in fish rating from Fair to Good over 10 years of monitoring.

Species lost since 2013 - Rock Bass (2 collected in 2013), Tonguetied Minnow (1 collected in 2013, state listed - Significantly Rare), Silver Shiner (1 collected in 2013), Kanawha Rosyface Shiner (3 collected in 2013, state listed - Significantly Rare), and wild Brown Trout (1 collected in 2013). Data Analysis Watershed - Drains a portion of eastern Ashe County and Southwestern Alleghany County, and is a tributary to the South Fork New River. The site is about 1 mile upstream of the creek's confluence with the river. Habitat - Very thin riparians and open canopy here, bordered by a tree farm on the right and a residence on the left. The left riparian vegetation in front of the residence (including a large Willow tree - see 2013 picture) has recently been entirely removed, and a large spoil pile now sits next to the house. Instream habitats consist of mostly swift, embedded sandy runs of variable depths. Riffles are infrequent, with only one located in the upper sample reach, where the channel is braided (instream island). The right bank is deeply cut and failing in the upper part of the reach, contributing soils to the stream. Consistently one of the lowest habitat scores in the New River basin. 2018 fish community - A moderately diverse and somewhat scarce fish community was collected in 2018. There were no new species records, but 5 gains and 5 losses since the 2013 assessment. In addition to the slight decrease in total abundance since 2013 (n=212 in 2018 vs. 380 in 2013), 1 fewer predator species, and 3 fewer intolerant species (7 in 2013) were collected in 2018 as well, resulting in a 4 point decrease in NCIBI score. However, the site retained its Good rating. Cranberry Creek is managed as NCWRC Hatchery Supported Trout Waters. Accordingly, all three species of stocked trout were collected, including 1 Brook Trout, 3 Brown Trout, and 1 Rainbow Trout, all ranging from 251-312 mm TL. Species with young-of-year cohorts in 2018 include Northern Hogsucker (n=3), White Sucker (n=1, no mature specimens), Bluehead Chub (n=5), Warpaint Shiner (n=1), Central Stoneroller (n=9), Mottled Sculpin (n=11), Mountain Redbelly Dace (n=3), Redlip Shiner (n=4), and Fantail Darter (n=5). 1998-2018 - There are 26 fish species known from this catchment, including 5 state-listed, and 9 intolerant species. Despite its lack of functional riparian vegetation and unstable banks, the fish community has shown fairly good long term trophic stability here, with 3 consecutive Good NCIBI ratings. Along with fairly stable water quality parameters measured over 4 basin samples, the fish community continues to indicate relatively consistent conditions in this watershed.

Species lost since 2013 - Redbreast Sunfish (1 collected in 2013), White Shiner (2 collected in 2013), and Silver Shiner (11 collected in 2013). Data Analysis Watershed - Drains part of rural northwestern Alleghany County, and is a tributary to the New River. This regional reference site is located about 3.5 miles upstream of the creek's confluence with the river. Habitat - Good forested riparian and canopy shading throughout the 600 foot sample reach. Good quality instream habitats including a mix of rocky riffles, runs, pools (one large/deep bedrock outcrop pool within the reach), and bedrock chutes. Some evidence of bank scouring on the outsides of channel bends from high flow events. However, no apparent habitat changes have occurred here since 2013. 2018 fish community - The 2018 sample represents the highest species richness at this location to date (21 total species), including 3 new records (Rosyside Dace, Warpaint Shiner, and wild Brown Trout), 3 state-listed species [Kanawha Rosyface Shiner (Significantly Rare), Kanawha Minnow (Special Concern), and Kanawha Darter (Significantly Rare)], and 6 pollution intolerant species (Rock Bass, Smallmouth Bass, New River Shiner, Kanawha Rosyface Shiner, Kanawha Minnow, and Kanawha Darter). The total NCIBI score was reduced by 10 points in 2018 due to a substantial increase in omnivores and herbivores present (Central Stoneroller, Bluehead Chub, and Mountain Redbelly Dace), which led to an overabundance of fish (n=1079 in 2018 vs. 768 in 2013). However, the site still rated Good with a score of 48 out of 60. Species with young-of-year cohorts in 2018 - White Sucker (n=7), Northern Hogsucker (n=5), Bluehead Chub (n=36), Central Stoneroller (n=2), Saffron Shiner (n=53), Kanawha Darter (n=6), Longnose Dace (n=2), Fantail Darter (n=2), Mountain Redbelly Dace (n=10), Warpaint Shiner (n=3), Western Blacknose Dace (n=12), and Smallmouth Bass (n=3). 1998-2018 - There are now 26 fish species that are known from this watershed, including 8 intolerant species, and 5 endemic species. The slightly elevated conductivity measurements here are consistent over basin cycles, and may be correlated to the increase in grazers and omnivores present in 2018. However, this site has maintained Good or Excellent NCIBI ratings over 4 fish community assessments since 1998, suggesting good, stable water quality in this catchment.

Species lost since 2013 - Kanawha Rosyface Shiner (1 collected in 2013). Data Analysis Watershed - Drains east-central Alleghany County and is a tributary to the Little River. This site is located about 0.3 miles upstream from the confluence. Habitat - Good riparian corridor here, with a mix of trees and shrubs providing equal sun and shade to this section of the stream. Row crops border the right bank just upstream of the sample reach. Instream habitats include shallow, sandy runs, a few bedrock shelves (some becoming buried in sand) with chutes, and infrequent short riffles. 2018 fish community - Good diversity and abundance at this fish community site, with 4 of 10 metric scores improving since the 2013 survey. The 12 point increase in 2018 resulted from a net gain of 3 species and an improved total abundance (n=548 in 2018 vs 141 in 2013), as well as improvements in trophic balance between insectivores and herbivores+omnivores. Ultimately, these improvements resulted in a third Good fish community rating here. However, only 2 of the 7 intolerant species known from this site were collected in 2018 [non-native Highback Chub (n=9), and the Significantly Rare Kanawha Darter (n=39)]. This stream is managed by NCWRC as hatchery supported trout waters, although no stocked trout were collected. Species with young-of-year present in 2018 - Brown Trout (n=5), Northern Hogsucker (n=8), Bluehead Chub (n=32), Bigmouth Chub (n=1), Redlip Shiner (n=44), Mountain Redbelly Dace (n=65), Western Blacknose Dace (n=6), Tessellated Darter (n=7), and Highback Chub (n=2). 1998-2018 - Twenty-three fish species are known from this site, with its close proximity to the Little River providing good recruitment opportunities, and certainly aiding the rebound in 2018. It seems that the 2013 sample was collected following extremely high flows in the watershed, which could explain the dip in species richness and abundance. Water quality parameters have remained relatively unchanged here, and despite lesser habitat qualities, this site has been rated Good in 3 of 4 NCIBI surveys.

Species lost since 2013 - Northern Hogsucker (4 collected in 2013), Spotfin Shiner (4 collected in 2013), and Kanawha Minnow (2 collected in 2013, state listed - Special Concern). Data Analysis Watershed - Drains the northeast corner of Ashe County with most headwaters located in Virginia. This site is only about 150 feet upstream of the New River confluence. Habitat - Mature forested riparian providing dense canopy in the upstream portion of the sample reach. The lower riparian is mostly residential lawn with shrubs on the stream banks. High quality instream habitats here are 100% high-gradient riffle/run/plunge pool complexes. No apparent habitat changes have occurred here since the 2013 fish survey. 2018 fish community - A highly diverse and moderately abundant fish assemblage was collected in 2018, with 9 species gains, including 6 new species records for the site [3 sunfish (Pumpkinseed, Bluegill, and Redear Sunfish), Bigmouth Chub and Bluntnose Minnow]. Also, 3 species were missing from the 2013 list [Northern Hogsucker, Spotfin Shiner, and Kahawha Minnow (state listed Special Concern)]. These differences in species richness come as no surprise given the opportunities here for fish movements in and out of the creek. As result, slight shifts in trophic structure and the percentage of species with multiple ages were seen, but with no effect on the overall NCIBI score and rating. Species with young-of-year ages in 2018 - Largemouth Bass (n=2, only specimens collected), Bluehead Chub (n=38), Warpaint Shiner (n=2), Smallmouth Bass (n=8), Mountain Redbelly Dace (n=1), Creek Chub (n=1), Longnose Dace (n=1), Rosyside Dace (n=1), Central Stoneroller (n=75), White Sucker (n=3), Appalachia Darter (n=1, only specimen collected, Significantly Rare species), Fantail Darter (n=13), and Mottled Sculpin (n=2). 2008-2018 - A highly diverse watershed, with 27 fish species known from this location, including new basin records for Redear Sunfish (non-native), and 10 other exotic species. Much of the upstream valley land use is in agriculture (pasture and row crops), with no riparian vegetation. Accordingly, slightly elevated specific conductance remains consistent here. Overall, this site has received 3 Good-Fair ratings with the NCIBI over a 10 year period, indicating little or no changes in water quality.

Data Analysis Watershed - Drains north-central Watauga County and is a tributary to the South Fork New River. Site is located about 2.5 miles upstream of the creek's confluence with the river. Habitat - Good quality forested riparians and canopy shading here. A few high-flow scour areas exist at bends within the sample reach, and a short section of the right bank is armored with caged/stacked rip-rap (see 2013 template picture). Instream habitats include swift rocky runs, and riffles, shallow plunges, and pools of various sizes. One long, deep pool in the upper part of the reach, holding several large trout. 2018 fish community - Moderate diversity and abundance observed here in 2018. Three fewer species collected than during the 2013 assessment, and a trophic shift towards more omnivores, as the dominant Bluehead Chub increased by 677% in 2018 (n=70 in 2018 vs. 9 in 2013). Also, 1 less intolerant species was encountered in 2018 (Kanawha Darter, state-listed Significantly Rare). Howards Creek is managed by NCWRC as Wild Trout Waters. Similar to all past assessments here, a total of 23 mature wild trout were collected (14 Rainbow Trout, and 9 Brown Trout). Species with young-of-year in 2018 - wild Brown Trout (n=10), wild Rainbow Trout (n=1), Mottled Sculpin (few), and Western Blacknose Dace (n=2). 1998-2018 - There are fish 20 species known from this site. Since 1998, this mostly forested catchment has exhibited low to moderate fish community abundance, but with moderate to good species richness. Habitat qualities and water quality parameters have been consistent here as well. Overall, the NCIBI may underestimating water quality in this higher elevation trout stream, with consecutive Good-Fair ratings over the last two basin cycles. However, the fish community's long-term species composition appears stable, signifying relatively unchanged water quality in this watershed.

The Little River eventually joins the New River in Virginia, a few miles north of the state line. Habitat - Good forested riparians at this regional reference site, but only moderate canopy coverage in the lower sample reach due to the parallel gravel road on the right. Diverse instream habitats here comprising riffle-run complexes, with a variety of depths and velocities, good pools, and a few bedrock outcrops with slides/chutes. No obvious changes in habitats since the 2013 fish survey. 2018 fish community - A fairly diverse and abundant fish assemblage was collected, including 4 intolerant species, 3 of which are state-listed, Significantly Rare [Tonguetied Minnow (n=1), Kanawha Darter (n=19), and Appalachia Darter (n=1)]. The NCIBI score improved by 4 points in 2018, due to an additional 2 species of cyprinids collected (minnows), and the site retained its Good rating. The stream is managed here as NCWRC Delayed Harvest Waters. Eleven stocked Brown Trout (250-560 mm TL), and one Rainbow Trout (289 mm TL) were collected and released.

Site borders the Boone Golf Club along the left bank. There are 4 minor NPDES dischargers in the catchment. Habitat - Extremely thin riparians here (one tree wide) providing little canopy shading to the stream. Banks are armored with boulder and concrete slabs along the right channel bends to deter bank erosion during high flow events. Instream habitats include swift rocky runs and riffles, and side-channel pools of various depths and velocities. No apparent habitat changes have occurred here since 2013. 2018 fish community - Moderate species diversity and good abundance of the fish assemblage, including 44 wild Brown Trout. However, no wild Rainbow Trout were collected (resulting in 1 less intolerant species in 2018), and no White Sucker were collected (1 of 2 sucker species here). This stream is managed as NCWRC Hatchery Supported trout waters. Accordingly, 1 stocked Brown Trout (203 mm TL) was collected and released.

Species lost since 2013 - Rainbow Trout (5 collected in 2013). Data Analysis Watershed - Drains western Ashe County and the northern tip of Watauga County, with much of its headwaters bordering the Tennessee line. Habitat - Fairly open canopy for most of the sample reach, with shrubs, grasses, and few trees vegetating the banks. Highway 88 runs parallel to the right bank, and row crops closely border the left. Instream habitats include mostly swift runs with some undercut/rooted edges, short riffles, and a few edge and boulder pools. No apparent changes to the riparian or instream habitats since 2013. 2018 fish community - A relatively diverse and highly abundant fish assemblage was collected, including 4 pollution intolerant species [Tonguetied Minnow (n=25, state listed - Significantly Rare), New River Shiner (n=3), Kanawha Minnow (n=2, state listed - Special Concern), and Kanawha Darter (n=49, state listed - Significantly Rare)]. Notable changes causing the 8 point drop in NCIBI score and bioclassification include a 65% increase in total abundance, and the loss of the intolerant Rainbow Trout. This section of the river is managed as NCWRC Hatchery Supported Trout Waters. Accordingly, two stocked Rainbow Trout were collected at 315 mm and 354 mm TL. 2018 also marked the first DWR records for two non-native sunfish species (Bluegill, and Green Sunfish). Species with young-of-year in 2018 - Brown Trout (n=6), White Sucker (n=4), Northern Hogsucker (n=5), Western Blacknose Dace (n=96), and Mottled Sculpin (n=2). 1998-2018 - There are now 21 fish species known from this catchment, and the fish community continues to exhibit good trophic stability here. The rating drop in 2018 does not necessarily indicate a substantial decline in water quality. Rather, the 2013 rating of Excellent seems to represent somewhat of an aberration from otherwise consistent scores and Good ratings over a 20 year period.

Data Analysis Watershed - Drains southcentral Ashe County, including the Town of Jefferson, the NC16/88 corridor, and the Jefferson Landing golf course community. The site is located about 625 feet upstream from the creek's confluence with South Fork New River. Habitat - Fairly good riparians and canopy shading in the lower half of the sample reach, then open canopy with grass covered banks in the upper half, within the golf course. Instream habitats are a mix of rocky runs, riffles, and pools of various depths. No obvious habitat changes have occurred since the last basin cycle. 2018 fish community - Slightly less diverse fish assemblage since the 2013 survey, with a 49% decline in total abundance (n=593 in 2018 vs. 1173 in 2013). However, the diversity and abundance metrics produced maximum scores of 5 in 2018, and 5 intolerant species were collected [Rock Bass (n=10), Smallmouth Bass (n=10), New River Shiner (n=1), Kanawha Rosyface Shiner (n=2, state listed - Significantly Rare), and Kanawha Minnow (n=1, state listed - Special Concern)]. Although the overall NCIBI score increased by 4 points in comparison to the 2013 assessment, the herbivorous Central Stoneroller continues to dominate the fish community here on account of the persistent non-point nutrient enrichment and lack of canopy in the catchment. One stocked Rainbow Trout was collected at 420 mm TL. Species with young-of-year cohorts in 2018 - Smallmouth Bass (n=1), Northern Hogsucker (n=4), Bluegill (n=7), Redbreast Sunfish (n=1), Largemouth Bass (n=1, no mature fish), Central Stoneroller (extremely abundant), Fantail darter (n=1), Bluehead Chub (n=1), and Mottled Sculpin (n=3). 2008-2018 - A species rich catchment, with 26 known fish species at this location, about half of which are non-indigenous to the New River basin. The close proximity to the South Fork New River provides good recruitment opportunities here, but the fish community continues to show trophic imbalance in this watershed. However, the highest NCIBI score was observed in 2018, and the site maintained its Good-Fair rating.

Species lost since 2013 - Saffron Shiner (1 collected in 2013), Kanawha Rosyface Shiner (1 collected in 2013, state listed - Significantly Rare), and White Catfish (1 collected in 2013). Data Analysis Watershed - Drains southeastern Ashe County, and is about 600 feet upstream from the creek's confluence with South Fork New River. Habitat - Mature forest riparian on the right side of the stream, but mostly open pasture on the left with no canopy (roughly equal sun and shade). Several non-vegetated breaks along the left bank from cattle (still with non-restricted access to the stream) and a tractor crossing at the upper end of the sample reach. Moderate to high quality instream habitats exist here, including extensive high gradient riffles, chutes, and bedrock shelves, separated by slower runs and pools. Fine silts occur along the slower edges of the stream and cover most of the rocky substrates in runs and pools. No apparent habitat changes have occurred since 2013. 2018 fish community - A diverse assemblage of fish was collected here in 2018, including three pollution intolerant species [Smallmouth Bass (n=1), Kanawha Minnow (n=1, new record, state listed - Special Concern), and Kanawha Darter (n=38, state listed - Significantly Rare)]. Changes in species composition since the last assessment (6 gains and 3 losses) are likely influenced by the close proximity to the river. However, trophic stability remains good here, with most metrics (8 of 10) showing maximum scores of 5, and the highest overall NCIBI score at this location to date. Species with young of year cohorts in 2018 - Brown Trout (n=2), Central Stoneroller (n=1), Mottled Sculpin (n=6), Bluehead Chub (n=2), Warpaint Shiner (n=1), and Western Blacknose Dace (n=1). 2008- 2018 - There are now 23 known fish species from this tributary to the South Fork New River. Notwithstanding the continued agricultural pressures on this watershed, this site has rated Good on 3 occasions, indicating biological stability.

Species lost since 2013 - Appalachia Darter (1 collected in 2013, pollution intolerant, state listed - Significantly Rare). Data Analysis Watershed - Small watershed that drains part of south-central Alleghany County; a tributary to the Little River. This site is less than 100 feet upstream of the creek's confluence with the river. Habitat - Good riparian corridor here, with mostly trees and shrubs, and good canopy shading throughout most of the 600 foot sample reach. Instream habitats are primarily rocky riffle run complexes with bedrock veins, side pools, and plunge pools within the steeper gradients. One scour pool with vertical clay banks and exposed tree roots is located mid-reach, and one large run-pool is located at the upper end of the reach. No apparent habitat changes have occurred here since the 2013 fish survey. 2018 fish community - A diverse and highly abundant fish assemblage (n=819 in 2018 vs. 323 in 2013, and 673 in 2008) for this small watershed. The only notable difference over the last basin cycle was the loss of the intolerant Appalachia Darter (state listed - Significantly Rare), which resulted in a 2 point decline for 2018. This creek is managed as NCWRC Hatchery Supported Trout Waters. Accordingly, 1 stocked Brown Trout (224 mm TL) and 2 stocked Brook Trout (257 and 276 mm TL) were collected and released. Species with young-of-year cohorts in 2018 include wild Brown Trout (n=11), White Sucker (n=1), Bluehead Chub (n=14), Redlip Shiner (n=33), Mountain Redbelly Dace (n=9), Rosyside Dace (n=2), Highback Chub (n=1), Tessellated Darter (n=2), Largemouth Bass (n=1, only specimen collected), and Western Blacknose Dace (n=6). 2008- 2018 - There are 17 known fish species from this location, with 14 of these taxa present in all 3 basin samples collected here. The Little River confluence, located just downstream, clearly provides good recruitment opportunities to this lower section of Pine Swamp Creek, and is likely at least partly the reason for the diversity and abundance here. Along with stable water quality parameters measured over three basin surveys, this site continues to support a trophically balanced fish community, with consistent Good NCIBI ratings.

Species lost since 2013 - Redlip Shiner (1 collected in 2013), and Rainbow Trout (1 collected in 2013). Data Analysis Watershed - Drains west-central Alleghany County and is a tributary to the South Fork New River (~750 feet downstream of the sample site). Habitat - The riparian corridor remains thin here, with hay fields bordering the left bank (and outside both upstream banks as well), and a residence bordering the right bank. Much of the stream's upstream riparian vegetation is thin or non-existent, as the stream runs through numerous pastures and crops. Instream habitats are 100% cobble and boulder riffle-run series here, with small boulder pools throughout. No apparent habitat changes have occurred here since 2013. 2018 fish community - A species rich and abundant (n=705) fish community was collected, including 5 intolerant species, three of which are state listed [Kanawha Rosyface Shiner (Significantly Rare), Kanawha Minnow (Special Concern), and Kanawha Darter (Significantly Rare)]. First DWR collections here for Green Sunfish (n=1), Bigmouth Chub (n=7), and Greenside Darter (n=2). Overall, the 6 point increase and rating improvement seen in 2018 was due to the increase in total species richness, including 2 additional darter species and 3 additional cyprinids (minnows). Prathers Creek is managed as NCWRC Hatchery Supported Trout Waters. Accordingly, 2 species of stocked trout were collected in 2018 - Brown Trout (246 and 262 mm TL), and Brook Trout (228 mm TL). Species with young-of-year cohorts in 2018 - Longnose Dace (n=3), Northern Hogsucker (n=3), Central Stoneroller (n=14), Bluehead Chub (n=15), Warpaint Shiner (n=11), Largemouth Bass (n=3, only specimens collected), Mottled Sculpin (n=21), and Mountain Redbelly Dace (n=24). 2008-2018 - There are now 24 fish species known from this location, with the nearby South Fork New River confluence functioning as good recruitment source for this site. However, the fish community here is still dominated by the herbivorous Central Stoneroller, and the omnivorous Bluehead Chub, as specific conductance remains slightly elevated from agricultural non-point enrichment in the upstream catchment. Even so, the NCIBI improved in the 2018 assessment, and the site gained its first Good fish community rating.

Species lost since 2013 - Greenside Darter (1 collected in 2013), and Rainbow Trout (3 collected in 2013). Data Analysis Watershed - Drains southeastern Ashe county, with this site located just 0.3 miles upstream from the creek's confluence with the South Fork New River. Habitat - One tree wide riparians are bordered by pastures on both sides of the stream in this lower section of the creek. Cattle are mostly restricted from the channel here, with one fenced access point located in the middle of the sample reach. Instream habitats are primarily cobble/gravel riffle-run series throughout, with one deeper run-pool at the bridge where the left bank is armored with boulder. No obvious habitat changes have occurred since the 2013 assessment. 2018 fish community - A species rich and abundant fish assemblage was collected in 2018, including 3 new species records [White Sucker (n=1), Tennessee Shiner (n=1), and Saffron Shiner (n=1)], and 3 intolerant species (Rockbass, Smallmouth Bass, and the significantly rare Kanawha Darter, all 3 present in past assessments here). With an additional 4 minnow species present, 2018 marked the highest NCIBI score to date, and the site's first Good rating. Roan Creek is managed as NCWRC Hatchery Supported Trout Waters. However, only one wild Brown Trout was collected in 2018. Species with young-of-year present in 2018 include Bluehead Chub (n=12), Northern Hogsucker (n=1), Central Stoneroller (n=5), Western Blacknose Dace (n=3), Mottled Sculpin (n=25), Fantail Darter (n=1), and Mountain Redbelly Dace (n=4). 2008-2018 - The overall fish community abundance remains quite high here (n=604 in 2018), despite a substantial drop from previous surveys (n=1273 in 2008, and 1138 in 2013). The close proximity of the South Fork New River surely provides good recruitment opportunities at this location. There are now 21 known fish species at this site, many of which are nonindigenous taxa, but few that are tolerant to pollution. Water quality parameters have remained relatively unchanged over 10 years at this location, and despite the prolific agricultural land use in the catchment's lower elevations, the fish community here continues to suggest stable water quality. Most Abundant Sp. 05/19/08 2008-41 14 48 Good Mottled Sculpin (n=178, 30%).

Non-Native Sp. Species Change Since Last Cycle Species gained since 2013 - Creek Chub (n=1, new record), and Appalachia Darter (n=4, 3 collected in 2008, state listed - Significantly Rare). Species lost since 2013 - White Sucker (2 collected in 2013), Rock Bass (3 collected in 2013), Tonguetied Minnow (3 collected in 2013), and wild Rainbow Trout (1 collected in 2013). A Watershed - Drains west-central Ashe County and is a tributary to the North Fork New River. Site is about 0.8 miles upstream of the creek's confluence with the river. C;Tr;ORW surface water classification. Habitats - Relatively thin riparian corridor at this location, with roads bordering both sides of the stream (lumber mill on the left), but still providing good canopy shading. Instream habitats include mostly riffle-run series, with some deeper runs and pools with slower velocities, and frequent bedrock shelves with plunges and chutes. No apparent habitat changes since the last assessment. 2018 fish community - Two fewer species collected compared to past assessments here, but still moderate species diversity and abundance, including two pollution intolerant darters [Kanawha Darter (n=21), and Appalachia Darter (n=4), both state listed - Significantly Rare]. Three Top Creek is NCWRC hatchery supported trout waters. Accordingly, 8 stocked Brown Trout (203 - 352 mm TL), four stocked Brook Trout (268 - 370 mm TL), and two stocked Rainbow Trout (242, and 380 mm TL) were collected and released. Species with young-of-year present in 2018 - Brown Trout (n=28), Western Blacknose Dace (n=3), and Mottled Sculpin (n=11). This relatively oligotrophic, high gradient catchment continues to support a high percentage of insectivores (93%) and a low percentage of omnivores+herbivores (5%) and remains unrateable with the NCIBI. 2008-2018 - There are 17 known fish species from this location. Water quality parameters measured over a 10 year period at this regional reference site are all similar, indicating no apparent issues. Although not rateable, water quality in this higher elevation ORW watershed seems unchanged. Most Abundant Sp.Fantail Darter (n=90, 28%), and Mottled Sculpin (n=81, 26%). Non-Native Sp.
