<br />It is staff's opinion that the 8 years of stream-flow data analyzed is representative of slightly <br />above 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 <br />(DEO) to identifY any potential water availability problems. There are four decreed surface <br />diversions within this reach of stream (Green Gulch Ditch, Marfitano Ditch, Shonyo Ditch and <br />Mundlein Ditch #2). According to the DEO, downstream senior water rights should pull enough <br />water through the proposed reach to satisfY the recommended instream flow in most cases. <br />Based on this analysis staff has determined that water is available for appropriation on Green <br />Creek, between the confluence of an unnamed tributary and the confluence with the South <br />Arkansas River, to preserve the natural environment to a reasonable degree without limiting or <br />foreclosing the exercise of valid existing water rights. <br /> <br />CWCB Staff's Instream Flow Recommendation <br />Staff recommends the Board fonn its intent to appropriate on the following stream reach: <br /> <br />Seament: Unnamed Tributary to South Arkansas River <br />Upper Terminus: Confluence Unnamed Tributary at <br />(Latitude 380 29' 27"N) (Longitude 1060 13' 21"W) <br />UTM ~ 42 60 773N 13 3 93 381E <br /> <br />Lower Terminus: Confluence South Arkansas River at <br />(Latitude 380 31' 39"N) (Longitude 106009' 09"W) <br />UTM ~ 42 64 771N 13 3 99 539E <br />NW SW Sl T49N R7E NMPM <br />385' East of West Section Line 2215' North of South Section Line <br /> <br />Watershed: Arkansas Headwaters (HUC#: 11020001) <br />Counties: Chaffee <br />Length: 4.7 miles <br />USGS Quad(s): Mt.
