<br />3. ALLOCATIONS <br /> <br />By "Resolution Regarding the Allocation of the Yield of the Closed Basin <br /> <br /> <br />Project" dated February 19, 1985, the RGWCD allocated "that portion of the yield <br /> <br /> <br />of the Closed Basin Project that is subject to 104(b)(1) of the Reclamation <br /> <br />Project Authorization Act of 1972, in a manner that it determines will best <br /> <br /> <br />benefit the lands and people within the District". The allocation resolution is <br /> <br />attached in Appendix A. <br /> <br />4. PHYSICAL FEATURES <br /> <br />A. Sal vage Well s <br /> <br />The 170 water salvage wells that have been constructed constitute the core <br /> <br />of the Closed Basin Division. These wells are all completed in the unconfined <br />aquifer and range from about 85 to 110 feet in depth. As the authorizing <br /> <br />legislation prohibited penetrating the first persistent confining layer called <br /> <br /> <br />the "Bl ue Cl ay" that forms the upper boundary of the artesian aquifer, much care <br /> <br />was given to determining the depth of the wells. The wells constructed under <br /> <br /> <br />the first contracts were physically logged to determine the maximum depths to <br /> <br /> <br />the top of the Blue Clay layer. Later contracts included the drilling of pilot <br /> <br />wells. Gamma-ray and resistivity logs were made of these pilot wells and analy- <br /> <br />sis made it possible to determine depth to the top of the Blue Clay layer, <br /> <br /> <br />establish well depths, length of screen, and depth of surface casings before <br /> <br />construction of the salvage wells. Individual wells yield water at rates <br /> <br /> <br />varying from 0.75 to 2.25 cubic feet per second (ft3/s). <br /> <br />Each well has been equipped with a waterproof, electrically driven, deep <br />well pump and enclosed in a concrete vault below ground. Gate valves permitting <br />discharge adjustment and flow rate meters have been provided. The discharge <br /> <br />5 <br /> <br />r.- - -~ ," ,..... <br />'v'..... ...... "'-1 tJ ~ <br />
