<br />1.3 <br /> <br />These objections are discussed qy means of a series of dia- <br />grams. Chart VIII shows a multi-purpose dam authorized by the recent <br />Flood Control Act. The scale is distorted, of course, in order to keep <br />the drawing within reasonable bounds. The length of the reservoir is <br />about 50 miles. Three water storage spaces are provided: <br /> <br />1. Dead storage of 890,000 acre feet necessary to get <br />head enough to operate the generating units. <br /> <br />2. Power storage of 1,400,000 acre feet used to regu- <br />late the river for power production. <br /> <br />.3. Flood storage space of 416,000 acre feet supposed <br />to be held empty for floods. <br /> <br />This project illustrates most of the objections to the multi- <br />purpose dam as a means of contro:uing floods. <br /> <br />1. It does not afford complete protection to the area <br />below. Over 2,500,000 acre feet of flood control <br />space would be needed to do that. It should be <br />noted that ir the dam were to be constructed solely <br />for flood protection, reasonably complete pr9tec- <br />tion could be afforded. <br /> <br />2. About 80,000 acres of land would be pernanently <br />flooded and removed from agricultural production <br />and about .30,000 acres flooded occasionally. <br /> <br />.3. Towns, railroads and highways would be flooded out. <br /> <br />4. The temptation would be present to encroach on the <br />flood control space for power production. <br /> <br />5. The reservoir would not be desirable from a recrea- <br />tion standpoint, because the large power drawdown <br />would expose an unsightly beach. <br /> <br />Chart IX shows how the multi-purpose project will act during <br />floods. As the flood control space will not completely control floods, <br />
