<br />. <br /> <br />PRIOR STUDIES <br /> <br />A number of flood control and flood plain management studies of <br /> <br /> <br />variDUS kinds have been published by different agencies for the Cache <br /> <br />la Poudre River basin. Table 3 lists these studies in brief summary <br /> <br /> <br />form. <br /> <br />In addition to the Corps of Engineers other Federal agencies <br /> <br /> <br />involved in flood plain management activities include the Federal <br /> <br /> <br />Insurance Administration, under the Federal Emergency Management <br /> <br /> <br />Agency, and the Soil Conservation Service. <br /> <br />Survey reports study a wide range of water resources problems. <br /> <br /> <br />Section 205 and Section 14 reports involve small ,projects for flo.od <br /> <br /> <br />control or streambank protection. The special studies are flood plain <br /> <br /> <br />information studies done under the Corps' Technical Assistance Program. <br /> <br />Other reports have been prepared by private consultant.s, local <br />governments, or universities. <br /> <br />FLOOD DAMAGE REDUCTION MEASURES <br /> <br />PHYSICAL IMPROVEMENTS <br />The Cache la Poudre River basin is laced with a complex system of <br />diversions, canals, and reservoirs. There are about 70 reservoirs Df <br />varying sizes, most in the plains region. Except for two large reser- <br />voirs on the North Fork Cache la Poudre River, storage reservoirs are <br />generally located on small tributaries or offstream and have little <br />individual effect on decreasing floodflows. Almost all reservoirs in <br />the basin are for irrigation or water supply; the exceptions are the <br />SCS dams on Boxelder Creek which were designed for flood control. The <br />operation of the reservoirs results in their being nearly full about <br />June, and there is little extra storage available during the flood <br /> <br />8 <br /> <br />. <br /> <br />season. <br />
