Previous work at the site included a fish <br /> <br />passage structure at the diversion dam to enhance migration. Colorado pikeminnow migrate <br /> <br />primarily in late June, July, and August. The razorback sucker migrates earlier than the Colorado <br /> <br />pikeminnow, typically in May and June. These migration times coincide with the irrigation <br /> <br />season. The purpose of this fish screen project will be to prevent or reduce the loss of <br /> <br />endangered fish in the canal. <br /> <br />Hvdrology <br />River flow data used in the design of the fishscreens was obtaiq.ed from the Concept <br /> <br />Development Report. The river flows in the vicinity of the GVIC diversion were determined <br /> <br /> <br />from gaging station information from the United States Geological Survey (USGS), flow data <br /> <br /> <br />provided by the Colorado Division of Water Resources, flow data provided by the Orchard Mesa <br /> <br /> <br />Irrigation District (OMID), and information from Reclamation and GVIC. The flows obtained <br /> <br /> <br />from these sources were used by Flo Engineering to determine the average monthly flows. <br /> <br /> <br />Monthly flow data was obtained for the years from 1965 to 1996, excluding 1984 and 1985. The <br /> <br /> <br />flows of interest in the design of the fishscreen are the average monthly flows during the <br /> <br /> <br />irrigation season. River flows used in the design of the fishscreens are near the location of the <br /> <br />bypass outlet. This will be downstream from the Orchard Mesa Irrigation District (OMID) <br /> <br />powerplant return flows. These flows are shown in the table on Sheet 1 of Appendix C. <br /> <br />5 <br />
