<.0 ~15T1NG FACILmES - HAMMOND PRO.JECT (CONTINUED> 2 D. Capability for enlarging storage capacity: Not Applicable E. Assessment of whether water conservation measures, other efficiency measures, or operational changes could make water available: I) Opportunities for "saving" water: . As part of the Colorado River Water Quality Improvement Program, about 28 miles ofthe Project distribution system will be lined to reduce the amount of water lost through seepage. Construction will begin in fiscal year 1997. See the Salinity Control Section for details. . Approximately 75 percent of Project farmland is currently under sprinkler irrigation. Conversion of the remaining farmland to sprinklers irrigation would reduce the water diversion requirements. Because much of the Project land is divided into small tracts, implementing typical outdoor urban/suburban water conservation measures such as efficient lawn sprinklers or xeroscaping would reduce the amount of water used. 2) How much: . About 5,600 acre-feet of water will be "saved" annually by lining distribution system. There are no estimates of the amount of water which could be saved by conversion of the remaining farm land to sprinkler irrigation or other conservation measures. 3) When . The water "saved" by lining the distribution system will be available during the historic irrigation season after construction is complete. The estimated completion date is the fall of2003. Much of the water that is currently lost through seepage from the canal system returns to the San Juan River and is presently available for use. Water conserved by other measures would also be available during the historic irrigation season. 4) Where: . The water would be available in the San Juan River at the existing point of diversion (Hammond Diversion Dam) or downstream. 5) Unresolved Issues: * * 1/10/97 - PR~UMINARY - SUBJECT To REVISION - FOR DISCUSSION PURFt051tS ONLY *.
