Abstract

Stream-discharge data collected from May 1982 through October 1985 and sediment data collected from March 1985 through October 1985 at stream flow-gaging station 09041500 Muddy Creek at Kremmling, Colorado, were used to determine total-sediment discharge into the proposed Wolford Mountain Reservoir. The data were divided on a seasonal basis, and statistical relations between suspended-sediment discharge and stream discharge were determined for the rising stage, falling stage, and base-flow period. One statistical relation between bedload discharge and stream discharge was determined from all collected data. These relations were used with 3 years of daily stream-discharge data to estimate total-sediment discharge. Total-sediment discharge was largest prior to the annual peak stream discharge during the study period and decreased thereafter. At least 97% of the total-sediment discharge was suspended sediment. Mean annual total-sediment discharge in Muddy Creek near Kremmling was estimated to be 83,000 tons per year for the 1983 through 1985 water years. Water-storage capacity of the proposed Wolford Mountain Reservoir at site C would decrease 10% after 100 years at this rate of mean annual total-sediment discharge. (USGS)
