<br />.' <br /> <br />2 <br /> <br />Water Availability - BLM is nol aware of any decreed surface diversions within the proposed reach, <br />but as mentioned previously, there are numerous surface diversions located upstream. BLM <br />recommends using USGS stream flow gage 09173500, operated from 1942 to 1951, as an indicator of <br />water availability. When using this data, adjustments should be made for the fact that the gage is <br />localed high in Ihe watershed and that several tributaries enter the creek between Ihe stream gage <br />location and the uppcr terminus of the proposed reach. <br /> <br />Relationship to Management Plans - This stream segment is important to BLM because the agency <br />manages much of the lands along the upper San Migael River corridor. Horsefly Crcek provides an <br />important spawning habitat for the San Miguel River fishery, and the stream is not heavily fished <br />because of difficult accesS. The riparian community along Horsefly Creek is in good condition for the <br />same reason, difficult acccss. The stream is part of BLM's Special Recreation Management Area <br />along the San Miguel River corridor, and it provides a resting spot for the numerous boaters who float <br />the San Miguel River. <br /> <br />The BLM requests that the Board recognize that this recommendation is based only upon the <br />minimum flows necessary to support cool and cold-water fishery values, BLM may wish to work <br />with the Board and/or through the Colorado water rights system to appropriate flows to optimally <br />protect fish values and to protect other water-dependent values specified in BLM resource <br />management plans. <br /> <br />,I <br /> <br />Data sheets, R2Cross output, fishcry 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 />If you have any questions regarding our instream flow recommendation, please contact Roy Smith at <br />303-239-3940. <br /> <br />~ /If ~<Aa <br /> <br />Linda M.
