<br /> <br />• 2 <br />In a high gadient stream such as Canyon Creek, maintaining depth is critical for providing <br />sufficient usable physical habitat over the winter months. This flow will also insure that <br />most of the pools associated with the main channel aze filled and that there is mobility <br />between pool environments. <br />Relationship to Management Plans. The Glenwood Springs Resource Management Plan <br />specifies that BLM will closely monitor Canyon Creek to insure that the fishery is maintained in <br />stable condition. BLM monitoring efforts over the last decade have concluded that habitat <br />limitations in the stream are mostly related to large flow events and large substrate size rather than <br />management of gazing and other uses in the creek corridor. The BLM is very interested in <br />protecting stream flows because Canyon Creek has natural barriers that make it an excellent <br />candidate for reintroduction of Colorado River Cutthroat Trout of high genetic quality. <br />The BLM requests that the Board recognize that this recommendation is based only upon the <br />minimum flows necessary to support cold-water fishery values. BLM may wish to work with the <br />Board and/or through the Colorado water rights system to appropriate flows to optimally protect <br />fish values and to protect other water-dependent values specified in BLM Resource Management <br />Plans. <br />Data sheets, R2Cross output, fishery survey information, and photographs of the cross section are <br />enclosed to support this recommendation. We thank both the Division of Wildlife and the Water <br />• Conservation Board for their cooperation in this effort. <br />if you have any questions regarding our instream flow recommendation, please contact Roy Smith <br />at 303-239-3940. <br />Sincerely, <br />~~~/(~ <br />James E.
