<br />... <br />, <br /> <br />2 <br /> <br />31. This flow will provide a transition period between snowmelt runoff flows and the very <br />low flow period from late summer through winter. <br /> <br />1.20 cubic feet per second is recommended from August 1 through February 28. BLM <br />analysis of flow regimes on the Uncompahgre Plateau shows that this is the amount of water <br />typically available in the stream during this time period. This flow will allow fish to survive <br />in pools and will prevent the riparian environment from being seriously stressed. <br /> <br />Water Availability - BLM is not aware of any surface diversions in the surveyed reach. Since there <br />are no gages on this stream reach, we recommend using the synthetic hydrograph methodology <br />developed by BLM for the Uncompahgre Plateau to obtain an estimate of water availability. <br /> <br />Relationship to Management Plans - BLM is engaged in a multi-year effort with other agencies and <br />partners to improve wildlife habitat conditions on the Uncompahgre Plateau. BLM's objectives for <br />Dry Creck include improving the health of an already diverse riparian community, and reducing <br />erosion from the surrounding landscape so that spawning and feeding conditions on the stream <br />substrate are improved. <br /> <br />BLM requests that the Board recognize that this recommendation is based only upon the minimum <br />flows necessary to support cold-water fishery values. BLM may wish to work with the Board andlor <br />through the Colorado water rights system to appropriate flows to optimally protect fish values and to <br />protect other water-dependent values specified in BLM resource management plans. <br /> <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 /> <br />[fyou have any questions regarding our instream flow recommendation, please contact Roy Smith at <br />303-239-3940. <br /> <br />:)ce:el~'t 1111 <br />rfVI '-'U/^ /1 (hL/t~~iL <br /> <br />Linda M.
