the rate of degradation is slow. The photographs also show examples of channel hydraulics, vegetative growth, old logjams, bankline slopes, stable and eroding bankline sediments, and the bedding material in the general channel. The sixth photograph shows the mass of sand sized sediment captured above an approximately eight foot high Beaver dam in Deep Creek. The hydraulic observations were then used by WWE to define the Manning's characteristics of the Deep Creek channel. The average discharge from the approximately four square mile drainage area is estimated at 1,900 acre feet/year. The maximum flood rates are 55.6 cfs (cubic feet per second) for 2-year recurrence, 114.1 cfs for 5-years, and 180 cfs per 100-years. The June 19, 2000 field observations determined the Manning's roughness coefficient (n) for this reach of Deep Creek to be approximately 0.065. This "n" correlates well with informatioin summarized in the USGS Water- Supply Paper #1849, titled "Roughness Characteristics of Natural Channels". The summary tabulation of hydraulics characteristics is presented within the report: The 2-year discharge is 55.6 cfs, in a channel averaging 9 feet wide, 1 foot deep, and sloping at 0.049 ft/ft. These characteristics project a average subcritical flow rate for Deep Creek of 5.1 ft/sec. The final section of the WWE report projects sediment yield for the observed reach of Deep Creek. The projections were analyzed using methods described by John G. Elliott, "Regionalization of Mean Annual Suspended-Sediment Loads in Streams, Central, Northwestern and Southwestern Colorado," a 1988 U.S. Geological Survey, Water - Resources Investigations Report 87-4193. Based on a mean annual runoff of 1,900 acre-feet (2.62 cfs), a mean basin elevation of 8460 feet amsl, and a drainage basin of 4 square miles, sediment load is predicted to vary from 330 tons/year to 660 tons per year. John Elliott recommends that these high and low values be averaged, which projects an average sediment yield of 495 tons/year. This yield is equivalent to a sediment load of 0.32 acre-feet/year or 0.08 acre-feet/square mile/year at a unit weight for sediment of 70 pounds/cubic foot. As the report summarizes; "Deep Creek between the Upper and Lower gaging stations is characterized by awell-incised channel with cobble- to boulder-sized rock common along the streambed. The stream transports significant volumes of sandy sediments, especially during peak flows, as evidenced by the large buildup behind the
