Slow Creek Restoration

Post-Construction Sampling

PROJECT SITE
The Slow Creek Restoration Project is in Cherokee County, NC and is in the mountain
ecoregion of North Carolina. The creek flows into Peachtree Creek and then into the
Hiwassee River and is within the Hiwassee River Basin. Slow Creek watershed above
the project site has a total drainage area of 1.75 square miles and is located in the eight
digit hydrologic unit code (HUC) 05020002. The stream is located east of Murphy off
US 62 between Hwy. 141 and Canyon Road loop (Figure 1).
The restoration site is near the headwaters of Slow Creek. The creek becomes a third
order creek at the confluence of the unnamed tributary at the half-way point of the
project. The project restored 1,320 feet of Slow Creek (Figure 2). The creek flows
through fallow fields, utility right of way and wooded banks. An unnamed tributary joins
with Slow Creek in the middle of the project, but is not a part of the restoration.
Preconstruction conditions can be seen in the photographs of the project site (Appendix
A).
' The property was formerly used for pasture and hay production. It is presently lying
fallow and has been sold as part of a small tract. The new owner has no plans to use the
area for livestock. There has been some additional soil work in the areas of the old
r channel where it was too wet initially to do final grading. The current owners are
leveling the old channel when conditions are dry.
t REFERENCE SITE
An upstream site on Slow Creek was utilized for a reference site for the restoration
project. The site was located on the upstream side of the Canyon Road bridge over the
creek. This section is wooded and flows between Highway 141 and a wooded slope.
Further upstream, Slow Creek flows through pasture areas that are currently being used to
pasture cattle.
METHODS
Standard quantitative collection methods were used for the reference site and two sites
within the project reach as the drainage area was >1.0 square miles in size. This
collection method consists of two kick net samples, three dip net samples, one leaf-pack
sample, two fine-mesh rock and/or log wash samples, one sand sample and visual
collections. Insects were picked/separated from the rest of the sample in the field.

' Organisms were picked roughly in proportion to their abundance, but not all organisms
were collected. If a species was identified, then only 10 individuals were collected. Pre
' and post construction samples were taken at three sites - above Canyon Road (reference
site), within the upper restored sinuosity area and near the end of the project reach (See
attached project site map). The reference site and the middle site were both above the
' confluence of the unnamed tributary. All taxa were picked and sent to a certified lab for
identification. The certified lab of Pennington and Associates, Inc. in Cookeville, TN
was used for the identification of the invertebrates.
' Cross section surveys were performed at two riffle areas and two pool areas.
Longitudinal profile was surveyed for the entire project. Pebble counts were taken at all
' cross section locations and a reach-wide pebble count was also sampled.
' RESULTS
Pre Construction Monitoring October 2002
t Benthic Macroinvertebrate Monitoring
The attached preconstruction results show all three sites experiencing some impairment
' to the biological community with similar biotic index values (Appendix A). The
reference site results showed similar values (EPT, No. of taxa) or even lower values
(Biotic index) than the project sites downstream. The lower site where the stream was
' experiencing the least instability had similar percentages of EPTs to the middle site
where the stream was experiencing more instability.
11
Pre-construction observations of the stream showed less riffle and pool sequences in the
upper reach than the downstream half. Overhanging vegetation along the stream bank
provided sources for woody structures and leaf packs in the stream. Sediment deposits
were noted in the creek. There was little to no vegetation immediately adjacent to the
waters edge. Due to the incised nature of the stream banks, root material at water level
was absent.
Vegetation Survival Plots 2003
Construction and plantings were completed in February 2003. Vegetation plots were
established, trees flagged and live stakes counted during the summer of 2003. Initial
results are shown in Table 1. Herbaceous cover was documented as initial conditions
after construction. Photo documentation of the vegetation plots can be found in
Appendix B.

Post Construction Monitoring March 2004
' Cross Section and Longitudinal Profile
' Post construction surveys of the restored channel were made in March 2004.
Longitudinal profile and four cross sections were surveyed. Pebble counts for the four
cross sections and one reach-wide section were documented. Data from the surveys can
' be seen in Appendix C. Photographs in Appendix C show as built construction
conditions in the restored stream.
' Post construction restored riffles and pools in the upper reach and vegetation was planted
along the stream banks. Sediment deposits were observed in the reach and the reference
site due to upstream impacts outside the project area.

Post Construction Monitoring October 2004-March 2005
Benthic Macroinvertebrate Monitoring
Vegetation Survival Plots
Cross Section and Longitudinal Profile
Bank Erosion Estimates
Pebble Counts
Sampling was not performed in September 2004 due to the high rain events from
hurricane remnants that crossed the region. Benthic macroinvertebrate monitoring,
vegetation survival, photographic documentation, bank erosion estimates and longitudinal
profiles were performed in October 2004. Cross section surveys were rained out twice
and were finally completed in March 2005.
Benthic Macroinvertebrate Monitoring
Benthic sampling results are shown in Appendix D for October 2004. The results in
Table 2 show all three sites experiencing some improvement to the biological community
with increases in numbers of organisms, taxa, EPT organisms and EPT Taxa. NC Biotic
Index showed improvement in the Reference Site and Middle Site between 2002 and
2004. There was a decrease in Biotic Index values for the Lower Site between 2002 and
2004, despite the increase in EPT numbers and taxa. In 2002, the lower site was
experiencing the least instability and so it may be the slowest to show improvement with
the restored stream design.
Vegetation Survival Plots
Vegetation was surveyed during October 2004 for live stakes, tree plantings and
herbaceous cover in the monitoring plots. The results for 2004 are show in Table 1. All
soil was stabilized and had established cover. Many volunteer trees and shrubs were
present. Many of the planted trees had poor survival and it appeared that the area had
been bush hogged after the trees had been planted. Volunteer tree and shrub species were
growing and replacing the initial plantings as can be seen in the photographs in Appendix
D.

Cross Section and Longitudinal Profile
Four cross sections and the longitudinal profile were surveyed and plotted in October
2004 and March 2005 and are shown in Appendix D. The longitudinal profile is shown
plotted over the previous profiles for tracking changes. There were some shifting of
7
L
pools and riffles between the first two years as shown in the longitudinal profile. No
major headcutting was observed and it appeared that the stream channel was adjusting to
a stable condition. All cross sections appeared to be stable as shown in the photographs
in Appendix D.
Bank Erosion Estimates
All of the banks appeared stable through most of the project area. Some minor bank
undercutting was occurring in the areas just downstream of the installed stream
structures. Some of the initial erosion around the pool bank pins may have been due to
the soil settling in the rock and root wad structures. No visible signs of bank erosion was
seen at the cross sections as shown by the photographs in Appendix D.

Cross Section #2 Riffle 0.00 0.00
Cross Section #3 Riffle 0.00 0.00
Cross Section #4 Pool 0.00 0.15'
Bank Erosion Hazard. Index was rated as Low for Slow Creek.
Pebble Counts
Pebble counts at each cross section and one reach wide count was done in March 2004
and March 2005. Results are shown in Appendix D. All sites showed the presence of
larger pebbles in 2005 than in 2004, but the overall component of Slow Creek was fine
gravels to silty clay particles.
FUTURE SAMPLING
Post construction sampling will be performed in September 2005, 2006, 2007 and 2008.
