<br />Cotton Creek Ditch, or in the natural channel of Cotton Creek) <br />suffers tremendous seepage loss, and it is for the purpose of <br />eliminating this seepage loss that the proposed project has been <br />planned. In the 1950's seepage loss was measured by using a <br />current meter in the mouth of the canyon and measuring the flow <br />in the ditch approximately 1-1/2 miles down the ditch. When 4.95 <br />cis was measured at the top all of the water was lost at 1-1/2 <br />miles down the ditch and of course none reached the end of the <br />ditch that day_ Another test was done in 1953 with 12.21 cts <br />measured in the canyon, 3.67 cis measured at the county road <br />approximately 2 miles down and 0.05 cts measured at the end of <br />the ditch. Thus, when 12 cfs is available in the canyon only a <br />trickle will reach the diversion point at the end of the ditch, <br />the rest being lost to seepage over the alluvial fan. The <br />project sponsors need to be able to deliver up to 30 cfs, even <br />during dry years. <br /> <br /> <br />r <br /> <br />~ <br /> <br />Diversion Structure and Headgate <br />Cotton Creek Ditch (and old Airline Ditch) <br />(Headgace is at arrow, left side of photo) <br /> <br />,...,b,1,ty of Rehabilitatioo ot the <br />Cotton Craak Airl1n.
