4.0 Reference StreamBasin Creek, located in Wilkes County in Doughton State Park, was used as the reference stream (Figure5). It was surveyed by a team of NRCS and NCWRC personnel (Angela Jessup, Dick Everhart, GregGoings, Jerry Pate and Joe Mickey) and by an NC SRI crew (Dan Clinton, Jan Patterson, Louise O’Haraand Jon Williams) in 1998. The original survey data from both surveys was acquired from the NC SRI.The data generated from those surveys was compared and used for design purposes. Biohabitats reviewedthe stream in the field in May 2007 and determined from a walk of the stream from the downstreamboundary of Doughton Park to above the confluence of Cove and Basin Creeks (approximately 2 miles ofstream), that it was a stable, suitable reference reach.4.1 Watershed CharacterizationThe Basin Creek watershed was delineated (see Figure 6) and the land uses within it are summarizedbelow. The watershed is approximately 98% forested, and less than 1% developed.Land Use In Basin Creek Watershed (Reference)Land Use Acreage %Deciduous Forest 3,963.2 91.3Mixed Forest 139.2 3.2Evergreen Forest 119.9 2.8Pasture/Hay 59.2 1.4Developed Open Space 20.7 0.5Shrub Scrub 20.0 0.5Woody Wetlands 13.6 0.3Developed Low Intensity 6.2 0.1Totals 4,342.0 1004.2 Channel ClassificationBased on the data collected in the field by both survey crews, the channel has a Rosgen Stream TypeClassification of C4.4.3 Discharge (bankfull, trends)The reference bankfull discharge, estimated from the N.C. Mountain Regional Curve isapproximately 425 cfs, and estimated from the N.C. Piedmont Regional Curve is approximately 300cfs. The NRCS survey discharge estimate using Mannings Equation is approximately 375 cfs. Thevery high percentage of forest land cover in the watershed (98%) serves to stabilize and maintainbankfull discharge quantities, which in theory should remain unchanged unless the developed areawithin the watershed increases, generating more stormwater runoff that reaches the channel.4.4 Channel Morphology (pattern, dimension, profile)The reference channel has a sinuosity of 1.1, a riffle bankfull cross-sectional area of 57 square feetand an average slope of 0.014 (see Table 4).
4.5 VegetationThe forest canopy is dominated by yellow poplar (Liriodendron tulipifera), white pine, red maple(Acer rubrum), hemlock (Tsuga canadensis) and sycamore (Platanus occidentalis). The understory isdominated by rhododendron and smooth alder along the stream. This community is most closelyrelated to a Rich Cove Forest classification (Schafale and Weakley, 1990).21
