HomeMy WebLinkAboutTAR 2017 Fish Community TemplatesSpecies Change Since Last Cycle Species gained since 2012 - Northern Hogsucker (2, last collected in 2006), Bluegill (9, last collected in 2006), and Yellow Bullhead (first collection at this location). Species lost since 2012 - Pirate Perch (1 collected in 2012), Creek Chubsucker (4 collected in 2012), Notchlip Redhorse (1 collected in 2012), Blacktip Jumprock (2 collected in 2012), Roanoke Bass (Sig. Rare, 1 collected in 2012), Bull Chub (2 collected in 2012), Mimic Shiner (Sig. Rare, 4 collected in 2012), Creek Chub (4 collected in 2012), and Glassy Darter (1 collected in 2012, and in most other previous samples). Data Analysis Watershed - Fishing Creek drains central Granville County, including the town of Oxford. This site is located about 3.5 miles upstream of the creek's confluence with the Tar River. Habitat - The riparian corridor at this location is mature and provides good shading given the >10 meter width of this stream. Instream habitats are high quality, extremely rocky Carolina Slate Belt types including frequent pools of mixed sizes and velocities, frequent shallow rocky riffles, and rocky runs. No apparent changes in instream or riparian habitats since the last basin monitoring cycle. 2017 - Moderate species diversity and abundance was observed. However, 2017 showed the lowest number of species at this location (n=17, same as 1997), with 6 fewer collected than in 2012. However, all lost species were represented by 4 or fewer individuals in 2012. Late season sampling at this site may be contributing to the slightly lower total species number due to post-spawn seasonal movement of some species out of this 600 foot reach. The total NCIBI score would have advanced to 54 (rating of Excellent), with just a few more individual fish collected. No disease was observed and the only young of year collected in 2017 were Largemouth Bass. 1992 - 2017 - This location has been sampled six times over the last 25 years, alternating between Good and Excellent NCIBI ratings. Overall, the fish community at this location on Fishing Creek indicates good water quality as it remains robust and trophically balanced. The few noticeable changes in fish species composition in 2017 are unlikely related to changes in water quality. Most Abundant Sp.Satinfin Shiner (136, 24%).Non-Native Sp.

Species lost since 2012 - Creek Chubsucker, Eastern Silvery Minnow, Pinewoods Shiner, Bluehead Chub, and Golden Shiner. Data Analysis Watershed - Drains northwest Franklin and southeast Vance counties. This site is located about 1.1 miles upstream of the creek's confluence with the Tar River. Habitats - The riparian floodplain here is wide, mature, and intact with coastal plain characteristics on account of it's close proximity to the Tar River (stream was out of its banks into the floodplain on June 20, 2017). Instream habitats are primarily sandy runs with abundant woody debris, frequent snag pools (some scoured at channel bends), no gravel/cobble riffles, but infrequent stick riffles and a few log chutes. No noticeable changes in riparian or instream habitats since last basin monitoring cycle. 2017 - The fish community continues to exhibit high diversity and abundance at this location and is dominated by insectivorous species (95%) including two intolerant darters (Chainback Darter and Roanoke Darter), which have been present during all DWR assessments. A majority of the 22 fish species showed multiple age classes in 2017 including 11 species with young of year cohorts. 1992 - 2017 - The fish community here continues to be dominated by intermediately tolerant insectivorous fish species, and only two exotic species ever collected. This site has shown similar metric scores and consistent Good bioclassifications in the last five basin assessments. Overall, Lynch Creek continues to support a stable fish community and shows no changes in water quality since the last basin cycle. Most Abundant Sp.Satinfin Shiner (30%)Non-Native Sp.

Species lost since 2012 - Creek Chubsucker (23 collected in 2012), V-Lip Redhorse (3 collected in 2012), Mountain Redbelly Dace (1 collected in 2012), and Rosyside Dace (14 collected in 2012). Data Analysis Watershed - The Middle Creek catchment is located just west of Franklinton and drains northwestern Franklin County. This site is about 0.3 miles upstream of the creek's confluence with the Tar River. Habitat - The riparian corridor at this location is mature and wide, and provides good canopy and shading to the stream. Instream habitats are primarily lower quality shallow sandy runs, side undercut pools under trees, and gravel riffles and chutes. A moderate amount of woody debris is also mixed into the shifting sandy channel. There are no apparent changes in instream or riparian habitats since 2012. 2017 - A highly diverse and relatively abundant fish community was collected here in 2017 including 3 insectivorous species considered to be intolerant to pollution (Pinewoods Shiner, Chainback Darter, and Roanoke Darter). Most of the 22 species collected here showed multiple year classes including seven that were also represented by young of year cohorts. The total NCIBI score of 52 is at the upper end of Good and would likely be advanced to Excellent (metric score of 54 - 60) with the occurrence of one more species such as the V-Lip Redhorse (sucker species present in 2012). 2002 - 2017 - Beginning in 2002, Middle Creek has been sampled at this location during 4 consecutive basin cycles and has rated either Good or Excellent each time indicating stable, high quality water.

Species lost since 2012 - Creek Chubsucker (3 collected in 2012), Largemouth Bass (2 collected in 2012), Highfin Shiner (1 collected in 2012), and Creek Chub (1 collected in 2012). Data Analysis Watershed - Red Bud Creek drains northeastern Franklin and northwestern Nash counties and is a tributary to Sandy Creek eventually Swift Creek. Habitat - Riparians are wide and intact at this location, providing good canopy and shading to the stream. The right riparian appears to be in regrowth following logging activities that occurred in the early 2000's. The stream channel in this reach of Red Bud Creek is straight with primarily shallow runs and several bedrock veins that create short cascade riffles. There have been no apparent changes in habitats since the 2012 fish community assessment. 2017 - A relatively diverse and moderately abundant community of fish was collected, with similar species composition as in past assessments including the presence of three intolerant species (Pinewoods Shiner, Chainback Darter, and Roanoke Darter). The trophic structure continues to be skewed towards a high percentage of insectivores, as in 2002 and 2007. Three species were collected here for the first time in 2017 during the site's 4th assessment (see below). Metric scores and the overall rating of Good in 2017 would have been advanced to Excellent with just a few more total fish collected. 2002 - 2017 - The fish community continues to exhibit good diversity and stability with three of four fish-community-based water quality assessment ratings of Good. No apparent changes in water quality are occurring in this regional reference site. Most Abundant Sp.Redbreast Sunfish (41, 20%)Non-Native Sp.

Species lost since 2012 - Golden Shiner (1 collected here in 2012), Chain Pickerel (2 collected here in 2012), and Brown Bullhead (1 collected in 2012). Data Analysis Watershed - Shelton Creek is located in the Tar River headwaters just west of Oxford, NC and drains west-central Granville County. This site is about 3 miles upstream of the creek's confluence with the Tar River. Habitat - The riparian corridor at this reference location is mature, intact, and provides a good canopy and shading to the stream. Instream habitats are primarily pools and runs of varying sizes and depths with infrequent, short, shallow riffles. No noticeable changes in instream or riparian habitats since the 2012 assessment. 2017 - The fish community here showed relatively high diversity in 2017 including two sucker species, six sunfish species (although 3 of 6 are non-native), largemouth bass, four minnow species (including the intolerant Pinewoods Shiner), one catfish species, and three darter species (including the intolerant Roanoke and Chainback Darters). The fish community here retains good trophic balance with the NCIBI showing only 3 of 12 metrics with less than maximum possible scores. 1992 - 2017 - Water quality remains high in this primarily forested headwater catchment, and there no apparent shifts in the fish community since 2012. NCIBI scores and ratings have remained stable here over the past 25 years, with 5 of 6 fish community ratings of Excellent. Most Abundant Sp.Bluehead Chub (51, 18%), and White Shiner (50, 17%).

Data Analysis Watershed - Drains southwestern Vance and western Granville counties including the I-85 and US-1 corridors. This site is about 1.7 miles upstream from the creek's confluence with the Tar River. Habitat - Mature, forested riparians provide good shading to this reach of Tabbs Creek. Moderate quality instream habitats including mostly shallow sandy runs and pools with an abundance of coarse woody debris in the channel, including several large logs. The habitat score was diminished mostly due to the dominant sand substrates and lack of functional riffles in the sample reach. However, no noticeable changes to the riparian or instream habitats in the last 5 years. 2017 - The fish community showed high species diversity and abundances, including good numbers for three intolerant species, and no diseases observed. About 70% of the fish collected in 2017 were represented by multiple age classes, and four species included young of year cohorts (including Chainback and Roanoke Darters, both intolerant). 1992 - 2017 - Tabbs Creek continues to be dominated by tolerant insectivorous fish species. However, consistent NCIBI metric scores and ratings of Good have been repeated here over several basin cycles. Good water quality remains noticeably unchanged in this Tar River headwater catchment.
