This reevaluation was necessary due to plan changes <br />and the presence of new standards for benefit evaluation. Irrigation <br />benefits were evaluated in the preceeding section. A summary of benefits <br />for other purposes to be served are presented below. <br /> <br />Flood Control <br /> <br />At the time of the 1973 llefinite Plan Report, flood control benefits <br />provided by the Corps of Engineers' April 10, 1969 letter were estimated <br />to be $1,599,000 annually. <br /> <br />Since that time, the Corps of Engineers has reevaluated the flood <br />control benefits. The current evaluation recognizes changes in <br />hydrology on the South Platte River downstream of Bijou Creek and changes <br />in their guidelines for computing benefits. On that basis, flood control <br />benefits have been reduced to $800,000 annually. <br /> <br />I' <br /> <br />---~. <br /> <br />The benefits are summarized in the Corps of Engineers' letter of <br />March 28, 1975, which is appended to this report. <br /> <br />18 <br />
