<br />. <br /> <br />December 12, 2005 <br />Page 7 of 15 <br />Working Draft for Discussion <br /> <br />Conditions of Use of les by T)'pe of Augmentation <br /> <br />Direetl}' Imported \\,Tater to the Colorado Rinr System <br /> <br />. <br /> <br />Descriotion <br />The sources ofwater that have been currently identified as water <br />augmentation through direct importation ofwatcr to the Colorado River <br />system include groundwater from non-tributary basins in Nevada. The <br />Coyote Spring Valley project would convey water through the Muddy <br />River to Lake Mead. The Three Lakes and Tikaboo Valley Groundwater <br />Project and the Northern Nevada Groundwater Development Project <br />(White Pine and Lincoln Counties) would convey water directly to <br />northeast Las Vegas, then enter Lake Mead via Las Vegas Wash return <br />flow. <br /> <br />Conditions <br />1. Recovery of imported water accumulated in Lake Mead would be <br />subject to a reduction to benefit the system. The amount of the <br />reduction would be equal to no more than 5% [or other amount to be <br />determined later] of the augmented amount. Once recovered from <br />Lake Mead, imported water becomes "mainstream water" for Decree <br />accounting purposes, including the determination of return flow <br />credits. <br /> <br />. <br /> <br />2. Permission to use ICS would be suspended during shortage <br />declarations; however, the Secretary would reduce the shortage in a <br />state to account for the amount of water imported by that state during <br />shortage conditions. <br /> <br />7 <br />
