Colorado 8021 a <br />Telephone (303) 2QT., 1 92 <br /> <br />REFER TO <br /> <br />. <br /> <br /> <br />. <br /> <br />Mr. John Hamill <br />U.S. Fish and Wildlife Service <br />Box 25486 - DFC <br />Denver, CO 80225 <br /> <br />FE".bruary 24,1992 <br /> <br />Re: Ruedi Reservoir Water Releases <br /> <br />. <br /> <br />The 20,000 acrefeet of water released from Ruedi'Reservoir in <br />1991 fell within our guidelines for angler acceptance and within <br />IFIM guidelines for providing good fish habitat. The data ~rom <br />Fish and Wildlife Service indicate that maximum flows in the <br />Fryingpan River remained below the 250 cfs limit that Barry <br />NGhring established as a fishable upper limit. The flow range of <br />150-250 cfs provides beneficial habitat for fingerling, juvenile <br />and adult life stages of brown trout, rainbow trout and brook <br />trout. Flows below 100 cis and above 300 cfs should be avoided. <br />The Bureau of ReClamation indicates that lake levels remained <br />within historic levels of the past five years. <br /> <br />The data from FiSh and wildlife Service indicate that the Ruedi <br />releases were measured in the Grand Valley and in some cases the <br />releases were 20% of the total flow in the river, which is very <br />significant. Some re-regulation of reservoirs in the upper basin <br />may have significant positive effects on Big River fishes; <br />however, it is important to keep such activities from damaging <br />existing fisheries. <br /> <br />Sincerely, <br /> <br />~j;-~ <br />Robert H. -~a~iey <br />Regional Manager <br /> <br />co.
