The <br />water is used when it is available and not when the crop needs it. <br /> <br />Other Agricultural Water Managemant <br /> <br />Controlled release rates from the reservoir storage will reduce <br />high water tables and induce ground water recharge which would be an <br />incidental effect of the project. <br /> <br />Nonagricultural Water Hanagemant <br /> <br />Public recreational and public fish and wildlife developmant are <br />objectives of the sponsors. Preliminary study of watershed yield indicates <br />there is not sufficient water to provide a full water supply to the <br />total irrigated acres. Recreation storage can be included in the plan <br />if a sponsoring group agrees to pay the construction and water cost for <br />this additional storage. The present stream flow down to about Saguachei <br />provides an excellent year-round sport fishery. <br /> <br />The reservoir storage for irrigation without recreational develop- <br />ment will provide incidental recreational opportunities to the public. <br /> <br />/ <br /> <br />~Iater Rights <br /> <br />Saguache Creek is a tributary to no stream, nor has it any compact <br />commi tmants. The owners of surface flow rights will have to change these <br />rights to storage rights through the court. <br /> <br />There are irrigation wells below the Town of Saguache which supplemant <br />the direct flow rights. These wells are good producers and continued <br />use is expected. <br /> <br />Character and Scope of Project <br /> <br />Structural Measures Needed <br /> <br />Although three sites have been surveyed, only one major site has <br />been considered. <br /> <br />Project measures needed include a multi-purpose irrigation stol"age <br />and floodwater retarding structure and about 40 miles of stream and <br />canal rehabilitation for irrigation water management. <br /> <br />/' <br />( <br /> <br />The reservoir will have a total capacity of about 15,250 acre-feet <br />of which 9,000 acre-feet is irrigation storage; 5,500 acre-feet is flood- <br />water retention storage; and 750 acre-feet is sediment storage.
