<br />. <br /> <br />. <br /> <br />. <br /> <br />OOiS1a <br /> <br />WEMINUCHE PASS DivERSlON <br /> <br />The Weminuche Pass Diversion would consist ofa ttansmountain <br /> <br />diversion from the Los Pinos River of the San Juan River Basin to the <br /> <br />Rio Grande Basin. The Rio Grande and Weminuche Pass Diversions. <br /> <br />of the San Luis Valley Project was authorized under House Document <br /> <br />693, 76th Congress, 3rd Session for a diversion of 20,000 Clcre-feet~. <br /> <br />The project was declared infeasible after a restudy. The uses on the <br /> <br />Los Pinos below Vallecito Reservoir reduced the amount of water that <br /> <br />wOl,lldbeavailable for the Weminuche Pass Diversion to that water <br /> <br />wl'\~ch would spill at the dam, or an annual average of'abbut 12,000 <br />, <br /> <br />acre-feet. This decrease in available water plus increased costs <br /> <br />made the proj ect uneconomical. <br /> <br />These potential upstream depletions for the 28 year period, 1928 <br /> <br />through 1955 are estimated by the Bureau of Reclamation to be as <br /> <br />follows: <br /> <br />Average Annual. <br />Depletions: in <br />Acre..Feet <br /> <br />San Juan-Chama Project, initial phase <br /> <br />105,100 <br /> <br />Pine River Project Extension, <br />ultimate development of. 69,000 acres <br /> <br />62,800 <br /> <br />Weminuche Pass Diversions <br /> <br />18,600 <br />186,500 <br /> <br />TOTAL <br /> <br />- '3v.- <br />18 <br />
