The mouth of Salt Creek is located nine miles <br />sOutheast of Gateway, Colorado. Baseflow is furnished by several <br />small springs at or near the mouth of Sinbad Valley. High flow <br />COmes from snowmelt and rainfall runoff. Surface flow i.n Salt <br />Creek is ephemeral and subsurface flow is perennial, yielding <br />approximately 100 gallons of water per minute or 160 acre-feet <br />per year. Concentration of salts in this water is 61,200 mg/L, <br />resulting in a total salt yield of 13,317 tons annually. If the <br />flow from these springs could be kept from entering the Dolores <br />River, the result would be a reduction of salt concentrations of <br />1.11 mg/L at Imperial Dam. Total annual costs (updated to <br />July '81 prices) ,per mg/L reduction at Imperial is $288,000. <br /> <br />.1 <br /> <br />The BLM proposed a system of collecting water using a <br />barrier dam, and pumping the water via a pipeline a short dis- <br />tance to be evaporated in four ponds. The site proposed for <br />the ponds is located just south of the proposed collection site <br />so as to reduce the length of the pipeline. <br /> <br />Initial BLM budgeting figures for 1982 have identified <br />money for advanced planning in the Sinbad Valley Unit. <br /> <br />II <br />I, <br />!I <br />I <br /> <br />(updated 11/20/81) <br /> <br />DS:cs <br /> <br />-31- <br />
