The Colorado Water Conservation Board <br />has requested the CDOW to provide an analysis on the recommended Instream flows for Rock Creek <br />based on the stream habitat improvement work completed by Queen of the River Fisheries Consultants on <br />property owned by Table Rock Ranch. <br /> <br />Rock Creek is located in western Colorado, approximately 1 mile north of the Town of McCoy. The CWCB <br />currently holds a 10 cfs year-round Instream flow water right (Case No. 5-77W3624) from the confluence of <br />Gore Creek to the confluence with the Colorado River, a distance of approximately 15 miles. The reach of <br />stream covered by this flow-sharing proposal begins Y. mile upstream of the confluence of Rock and Egeria <br />Creeks and extends to the lower Table Rock Ranch property boundary, a distance of approximately 2.3 <br />miles. The Colorado Division of Wildlife (CDOW) collected additional stream cross section data on Rock <br />Creek in August 1985 and September 2004. Rock Creek is classified as a medium stream (between 20' to <br />35' wide) above the confluence of Egeria Creek and a large stream (between 36' to 59' wide) below the <br />confluence with Egeria Creek. Fishery surveys indicate the stream environment of Rock Creek supports a <br />self-sustaining brown, rainbow and brook trout fishery. Rock Creek also supports populations of Mottled <br />sculpins, Longnose suckers and White suckers. <br /> <br />Rock Creek Data Summary <br />The stream cross section data was analyzed using the R2CROSS program. The R2CROSS output was <br />evaluated using the methods described in Nehring (1979) and Espegren (1996). The CDOW selected three <br />different sites for stream cross section data collection in 2004, in addition to the two cross sections sites <br />selected in 1985. Two sites, X-Sections 1 & 2, were located on Rock Creek upstream of the confluence with <br />Egeria Creek and three sites, X-Sections 3 - 5 were located on Rock Creek downstream of the confluence <br />with Egeria Creek. X-Section #3 was located downstream of the proposed Oxbow Diversion but upstream <br />of the Oxbow Diversion return flow, X-Section #4 was located downstream of the Oxbow Diversion return <br /> <br />DEPARTMENT OF NATURAL RESOURCES, Russell George, Executive Director <br />WILDLIFE COMMISSION, Philip James, Chair.
