Sediment Discharge in Fortification Creek and the Effect of Sedimentation Rate on the Proposed Rampart Reservoir, Northwestern Colorado

摘要

The report presents estimates of the total-sediment discharge in Fortification Creek at the proposed Rampart Reservoir site and the sedimentation rate of the reservoir. Sediment (suspended and bedload) and stream-discharge data collected at streamflow-gaging station 09246920, Fortification Creek near Fortification (hereinafter referred to as the Fortification Creek gage), during water years 1985-87 were used to estimate the total-sediment discharge at the proposed reservoir site. The Fortification Creek gage is located about 1 mi downstream from the damsite.
