<br />Evaluation area D includes 1,190 acres of land with various soil conditions, <br />located in the river valley adjacent to the Florida River. These lands will <br />receive a smaller increase in water supply than will those in evaluation <br />areas A, B, and C. <br /> <br />Soils <br /> <br />Basic soils data were obtained from individual farm soil surveys previously <br />made in the regular activities of the Soil Conservation Service. These <br />surveys were augmented where addi tional information was needed. Soil surveys <br />also were supplemented by detailed soil profile descriptions and analytical <br />data on representative soils of the project. Copies of the Bureau of Recla- <br />mation land classification field sheets for the project were supplied to the <br />Field Party. <br /> <br />The 7,020 acres in evaluation area A are in land capability class II. !I <br />The 9,820 acres in evaluation area B are in capability class III. Ninety- <br />three percent of the 1,u20 acres in evaluation area C is capability class <br />IV, and seven percent is capability class III. Evaluation area D comprises <br />1,190 acres of which 50 percent is in capability class IV, 25 percent in <br />capability class III, and 25 percent in capability class II. <br /> <br />It is concluded that the 19,450 acres of lands designated as the Florida <br />project are suitable for culUvation under irrigation. <br /> <br />Irrigation Supplies and Requirements <br /> <br />Several studies of irrigation requirements have been made in the general <br />vi dni ty of the Florida project. These data, wi th additional information <br />supplied by personnel familiar with the area, were used in determining <br />i rri gation water requirements. In the past, water-supply shortages have <br />been in excess of 50 percent of requirements during years of low runoff. <br /> <br />Based on a weighted average net seasonal consumptive use of 1.28 acre-feet <br />per acre, and an estimated weighted average farm irrigation efficienqy of <br />53 percent, the average water requirement at the farm headgate will be 2.42 <br />acre-feet per acre. <br /> <br />Based on a period comparable to 1928-1956, whi ch was selected as the pre- <br />project study period, the proposed facilities will deliver an average of 2.28 <br />acre-feet of irrigation water at the farm headgate, thus meeting 94 percent <br />of the average water requirements of the project lands. A 100 percent water <br />supply will be available for project lands on an average of 7 out of 10 years. <br /> <br />!I Land capability classes are in accordance with the national land capa- <br />bility classification, Soil Cbnservation Service Soils Memo No. 22, <br />May 19, 1958. <br /> <br />iii <br />
