The depletion rates for a 100 percent water <br />supply computed by the Blaney-Criddle method were decreased to allow for <br />anticipated irrigation shortages. The following shows the derivation of <br />project stream depletions. <br /> <br />. <br /> <br />100 percent water supply <br />Cropped lands <br />Incidental areas <br />Total <br />95 percent water supply <br />Cropped land and <br />incidental areas <br />New evaporation from <br />reservoir basin <br />Total new stream <br />depletion <br />11 ' Based on project area <br /> <br />Stream depletion <br />Acre-feet <br />per acre of <br />cropped lands <br /> <br />Total <br />acre-feet <br /> <br />0.84 <br />.20 <br />1.04 <br /> <br />0.99 <br /> <br />Y3,560 <br /> <br />270 <br /> <br />3,830 <br />of 3,600 acres <br /> <br />A.gricu1.tuTaJ. Economics <br /> <br />Crops that can be successfully grown under irrigation farming are <br />limited by climatic conditions to meadow hay and pasture, usually native <br />grasses, small grains, and some hardy garden vegetables. The principal <br />agricultural enterprise in the project area consists of beef cattle and <br />sheep raiSing with forage produced as feed on irrigated farm lands to <br />supplement the grazing on surrounding range lands. Beef cattle predol!li- <br />nate but a few operators have both cattle and sheep. <br /> <br />The present type of farming would not be expected to change mate- <br />rially with proj ect development. Increased crop prod--.lction would, however, <br />permit an increase in the number of livestock in the area. Range permits <br />are fully subscribed under present conditions and the project would not <br />affect range feed production nor utilization. <br /> <br />A fa:rm budget ano.lysis \las made fOT a beef type farm which is <br />assumed to be representative of the type that could be expected with proj- <br />ect development. Anticipated payment capacity and irrigation benefit <br />determinations were based on this representative farm budget., <br /> <br />. <br /> <br />The budget analYSis was made on the basis of the long-term pro- " <br />jected price level of 215(1910-14=100). Data on crop yields, prices, <br />land use, farm practices, and land development costs were obtained from <br />local interviews in the project area and neighborinG areas having approxi - <br />mately the same climate, elevation, rainfall, and growing season.
