<br />000858 <br /> <br />Dam Safety Office in Denver has concluded that any operations above elevation <br />240 and up to elevation 251 exceed guidelines for static and seismic risks. The <br />installation of a filter blanket is believed to be able to allow Senator Wash to <br />operate at elevation 240. <br /> <br />Any repair that would leave Senator Wash out of operation for any prolonged <br />time period during the current drought should be deferred until additional water <br />management reservoirs can be constructed. The construction and funding of <br />additional water management reservoirs should be expedited. <br /> <br />AUTHORITY: (identify existing or new) <br />COST: <br />FUNDING SOURCE: <br />ENVIRONMENTAL DOCUMENT: (categorical exclusionlEIS/other) <br />ENVIRONMENTAL OR ESA ISSUES: <br />NEED FOR RULES AND REGULATIONS: <br /> <br />· Accelerate the development of the proposed additional Lower Colorado <br />water management reservoir(s). These re-regulating reservoirs are to <br />compliment or replace Senator Wash Reservoir and can conserve up to 300,000 <br />acre-feet of water per year and are currently scheduled to be completed by 2008. <br />A joint Reclamation / California agencies evaluation of alternatives is nearly <br />complete. <br /> <br />AUTHORITY: (identify existing or new) <br />COST: <br />FUNDING SOURCE: <br />ENVIRONMENTAL DOCUMENT: (categorical excIusionlEIS/other) <br />ENVIRONMENTAL OR ESA ISSUES: <br />NEED FOR RULES AND REGULATIONS: <br /> <br />· Improve coordination of daily water supply operations. There are <br />opportunities through improved coordination of daily operations between <br />Reclamation and water users for water users to adjust their daily operations, <br />within certain limits, to benefit overall water operations thereby conserving <br />system water. With respect to the lower Colorado River, the three-day travel time <br />for water released from Parker Dam to reach Imperial Dam, coupled with minimal <br />regulating storage capacity in this reach of the River, presents a challenge to <br />Reclamation staff in meeting scheduled deliveries precisely. This should be <br />undertaken as a Reclamation initiative in conjunction with water users. <br /> <br />-3- <br />
