It is staffs <br />opinion that the 12 years of stream-flow data analyzed is representative of average water-years. <br /> <br />Existing Water Right Information <br /> <br />Staff has analyzed the water rights tabulation and consulted with the Division Engineer Office to <br />identify any potential water availability problems. There are no decreed surface diversions within <br />this reach of stream. Based on this analysis staff has determined that water is available for <br />appropriation on Cottonwood Creek, from Headwaters to the East Canyon Creek, to preserve the <br />natural environment to a reasonable degree without limiting or foreclosing the exercise of valid <br />existing water rights. <br /> <br />CWCB Staffs Instream Flow Recommendation <br />Staff recommends the Board form its intent to appropriate on the following stream reach: <br /> <br />SeQment: Slaughter Spring Gulch to Anderson Ditch <br /> <br />Upper Terminus: Slaughter Spring Gulch at <br />(Latitude 390 32' 11") (Longitude 107002' 15") <br />Lower Terminus: Anderson Ditch at <br />(Latitude 390 34' 02") (Longitude 107002' 09") <br />Counties: Eagle <br />Length: 2.2 miles <br />USGS Quad(s): Cottonwood Pass <br />Flow Recommendation: 1.70 cfs (May 15t - October 31 5t) <br />1.30 cfs (November 1 st - April 30th) <br /> <br />Cottonwood_Creek_ISF _RPT_ vI.doc <br /> <br />- 5 - <br />
