Existing Water Right Information <br />Staff has analyzed the water rights tabulation and contacted the Division Engineer Office (DEO) <br />to identify any potential water availability problems. There are no decreed surface diversions <br />within this reach of stream but the reach ends at the head gate of two water rights: Mesa Ditch <br />(88.0 cfs, 1877/1884/1888/1917 /1949/1961 appropriations) and Big Rock Ditch (17.5 cfs, 1970 <br />appropriation). Staff has determined that water is available for appropriation on Cochetopa <br />Creek, between the confluence with Nutras Creek and the Mesa Ditch Headgate, to preserve the <br />natural enviror vent to a reasonable degree without limiting or foreclosing the exercise of valid <br />existing water rights. <br />CWCB Staffs Instream Flow Recommendation <br />Staff recommends the Board form its intent to appropriate on the following stream reach: <br />Segment: Confluence with Nutras Creek to Mesa Ditch Headgate <br />Upper Terminus: CONFLUENCE WITH NUTRAS CREEK <br />(Latitude 38° 03' 22.43 "N) (Longitude 106° 48' 25.26 "W) <br />UTM North: 4213595.32 UTM East: 341463.57 <br />NW SW S19 T44N R2E NMPM <br />140' East of the West Section Line; 2680' South of the North Section Line <br />Lower Terminus: MESA DITCH HEADGATE <br />(Latitude 38° 8' 8.56 "N) (Longitude 106° 45' 38.01 "W) <br />UTM North: 4222336.89 UTM East: 345707.16 <br />NW NE S28 T45N R2E NMPM <br />2420' West of the East Section Line; 1160' South of the North Section Line <br />Watershed: Tomichi (HUC #: 14020003) <br />Counties: Saguache <br />Length: 8.98 miles <br />USGS Quad(s): Elk Park, Cold Spring Park <br />Flow Recommendation: 11.3 cfs (May 16 — August 15) <br />7.5 cfs (August 16 — September 30) <br />4.5 cfs (October 1 —November 15) <br />2.75 cfs (November 16 — March 15) <br />5.0 cfs (March 16 — May 15) <br />-7- <br />
