Benthic Monitoring
Introduction:
This project involved the relocation and restoration of a smaD, unnamed tributary to East
Fork (UT -East Fork). East Fork. is a major headwater tributary of the South Fork of the
New River. The project site is east - southeast of the Town 0 . atauga County,
NC. Construction of the relocated reach was comp May of2ool.
UT -East Fork is a first order stream with a drainage area 0 app Xiinately 100 acres. The
Restored Reach is located at the mouth of the stream where it ftows into another first
. order stream approximately 100 meters above East Fork. The Reference Reach is located
approximately 300 meters above the Restored Reach; the drainage area of the Reference
Reach is approximately 60 acres. . .
This is the year-2 sample and analysis. The next sample will be collected in April of
2004.
Procedures:
The Qual-4 methods outlined in the SOP and Technical Guidance were followed in the
collection of samples. The Reference Reach was sampled 5/01103, the Restored Reach
was sampled 4/22/03, both samples were preserved in 95% ethanol and shipped to
Pennington and Associates for analysis on 5/12/03. The sampling team consisted of John
Vilas, Adam Williams and At Childers, all with E'p.V Environmental Consulting Services
Inc.
Results:
Pennington and Associates analyzed collected benthos samples for both the Restored
Reach and the Reference Reach, results were returned July 8, 2003 and are included in \ , ~.
this report. A summary of these results follows: tPOUJ . {~
1. Overall abundance and richness for the Reference site are 314 and 24 ~ /
respectively, wbereas these same values fur the Restoted reach are 81 and 14.
2. EPT abundance and richness for the Reference site are 281 and 13 respectively,
these values for the Restored reach are 58 and 5 (see Benthic Analysis).
3. The Biotic Index value for the Reference reach is 4.16 (good water quality) and
for the Restored reach is 5.69 (good-fuir water quality).
4. Stoneflys (pleCoptera) and Caddisflys (Trichoptera), non-tolerant species, were
more prevalent in the Reference reach versus the Restoredreacb. Total P1ecoptera
abundance (taxa) in the two reaches are 36 (4) and 1 (1) respectively. Total
Tricoptera abundance (taxa) in the two reach are 76 (2) and 1 (1).

5. The Biotic Index value for the Reference reach changed from a 2.9 in 4/01 to a
4.16 in 5/03.
6. Habitat Assessment Forms completed for both sites also show the Reference
reach to have a higher quality aquatic habitat (Reference score=82; Restored
score=71) (see Habitat Assessment Forms).
7. The Reference reach is a B4 stream type with a D50 of approximately 4mm
(5/21/01). A pebble count was not performed on the Reference reach this year.
The Restored reach, an E5 stream type, had a D50 of <0.062 mm in 9/01, and a
more recent D50 of 0.17 mtn (4/03) (see pebble counts).
Discussion:
The results of the benthic analysis performed on the Restored site and the Reference site
indicate a significant difference in 18ctors relevant to macrobenthos colonization, survival
and population dynamics between the two reaches. There does not seem to be a clear
indication of which 18ctor or 18ctors are most . significant. The most likely candidates to
explain the. variation in sampled results, in our opinion, include: .fr
vd f .uJC ..(
. Relative age and maturity of reach .U _I' ~~f~
. Mean particle size l -tf ~ 5 O~.
. Stream type . c? '\ LJ:>ff
. Water quality influence from watershed "tJ
. Sampling error, influence from recent rain event
The relative age and maturity of the reaches we feel is higbly significant in that the
Restored reach is still in a period of adjustment. This adjustment period is likely to be at a
maximum for priority-one type restorations (complete new clumnel construction) as
opposed to priority-two or three type restoration where the disturbance to the existing
streambed during construction is sporadic (priority-two) or limited (priority-three). The
type of adjustment most likely to afiect macrobenthos recolonization and survival is the
sorting of particles in the stream bed and the tl1}~ing of the excess fines left over ftom
construction. This process will continue until a sufficient number ofbankfull events
occurs such that an equilibrium is reached between the energy in the channel and the
available sediment. Other significant fi1ctors related to the age and maturity of the
channel are the lack of embedded and established large organic matter (logs and sticks)
within the channel and the lack of habitat niches such as undercut banks or debris snags.
As noted in the previous paragraph, the Restored reach is still in a period of adjustment
with respect to mean particle size in the bed. An increase in the size ofD50 was noted on
the Restored reach ftom 9/01(<0.062 rom) to 4/03 (0.17 rom). It is anticipated that this
reach will continue this trend and become coarser over time; we expect that as the bed
becomes more coarse benthos abundance and richness values will increase. It is not
expected that the Restored reach will become as course as the R.efurence reach given that
the Referenee reach is a much steeper B type channel Our expectation is that the
Restored reach will eventually have a consistent D50 between the current value of
0.17mm and the D50 measured for the Impact reach, O.8mm. The DSO measured in the

Reference reach (4mm.) is significantly larger than even the Impact reach and we feel that
this difference, if maintained over time, will be sufficient to limit overall richness and
most significantly EPT richness in the Restored reach.
Stream classification, as defined in Rosgen, 1996, is based on a system of ordered sets of
specific hydraulic and sediment relationships within and between rivers. The
measurement of elements of a given stream reaches' dimension, pattern, profile and
sediment cbaracteristics allows for that reach to be classified along a continuum of
defined stream types. The Reference reach is a B4 type stream, slope between 2% and
4%, more oxygen rich waters, less sinuosity, narrow sloping floodpJain, and streambed
dominated by small gravel The Restored is an E5 stream type, slope less than 2%, highly
sinuous, broad floodplain, and a streambed dominAted by sand. The most significant
differences between the two stream types with respect to macrobenthos are slope and
mean particle size. Particle size bas been discussed in the previous section. We feel slope
is significant in that channels with steeper slopes often have coarser bed material and are
domimlted by riftle and run sections with shorter pools. Channels with flatter slopes often
have finer bed material, and are more evenly split between riftles and runs and pools and
glides. While these differences may not necessarily affect overall abundance and
richness, we feel they may influence the general makeup of the population such that
certain species that thrive in theB4 stream may not do as wen in the E5 stream. If the E5
stream was recentlyconstrueted, recolonization would be primarily through drift, a
process limited by the upstream population. It may require additional time for the newly
constructed channel to be introduced to species, not prevalent in the upstream reach, that
are better able to thrive in the new habitat.
Water quality, particularly high sediment loads from upstream, we feel may be a :fBctor
influencing the benthos population in the Restored reach. The area. of stream that lies
between the Reference and Restored sites (the Middle reach) bas severe bank. erosion,
deep incision, and severe entrenchment. This reach is a 04/5, which is an inherently
unstable stream type frequently associated with accelerated bank. erosion and bed scour.
Land use along the Middle reach consists primarily of a trailer park and apartments on
the right bank and low density residential on the left bank. When surveying/sampling
(4/03), the Restored. stream was Jittered with trashcan lids, plant pots, newspaper, and
other trash from the land uses along the Middle reach. By contrast the Reference stream
is dow1mated by bay-fields and pasture, undeveloped land, and low-density residential
development. There was no trash or non-organic debris noted in the Reference stream.
The net effect ofbank instability, impervious runo1l: and human inftuences (trash,
mowing grass) from the Middle reach, may possibly reduee the numbers of some
intolerant benthic species present (ie: stonefly) in the Restored site while others may
remain present (ie: mayfly).
Sampling error is always a possibility and we make every reasonable attempt to avoid
such error. For this sample we do not have any reason to suspect any error associated the

actual collection, preservation or analysis of the samples. However, we feel that the
timing of the collections and the antecedent weather could be a :fBctor. The Restored
reach was sampled on 4/22/03. On 4/17 there was a 2.4-inch rain event and on 4/10 there
was another 2.4-inch rain-on-snow event. It is possible that the Restored reach bad not
sufficiently recovered from two heavy rain ev~ one of which was 5 days prior to the
sampling. The Reference reach was sampled on 5/1/03. On 4130 there was a O.4-inch rain
event but no other rain since the large rain of 4/17. In undeveloped watersheds in the
mountains a O.4-inch ra.in generally results in only minimal increases in stream flow. It is
possible that the heavy rains of early spring may be in part responsible for the change in
Biotic Index calculated for the Reference reach.
Key Questions for 2004 Sample:
1. Will Biotic Index for Reference reach decline toward the previous level? Will
controlling for optimal sampling conditions affect this?
2. Will the stream bed in the Restored reach continue to coarsen?
3. How much of amctor is the Middle reach?
4. Will the proposed construction of the Assisted Living Facility impact stream quality?
