Although not an exhaustive list, the study identifies 21 potential water conservation measures and evaluated their potential water savings. Structural and on-farm water conservation projects which are evaluated include canal concrete lining, lateral interceptors, regulating reservoirs, tailwater return systems, drip irrigation, sprinkler irrigation and greater delivery flexibility. The on-farm programs would be implemented by willing landowners on a voluntary basis. The extent of potential landowner participation remains to be determined. The report also evaluates the potential conservation opportunities associated with the reclamation or reuse of eflluent, drainwater, groundwater and water from the New and Alamo rivers as well as from the Salton Sea. The report does not quantify the water savings potential from crop rotation, idling or fallowing of farmland. The final phase of the study addresses two issues: 1) the estimated quantity of water that can be conserved and made available for future use and/or transfer; and 2) the identification of potential environmental concerns and mitigation strategies related to the water conservation projects. The study concludes that environmental impacts of each identified conservation measure appears to be either minimal or can be fully mitigated. The Draft Water Requirements and Availability Study is available for review in public libraries around Imperial County and in the District's Community Relations office, 333 E. Barioni Blvd., Imperial. Copies are available for $10 by calling 339-9426. Public comments on the document will be taken until Feb. 22. All written comments that are received will be addressed in the Final Study, which will be presented to the Board for approval in March. # # #
