The severity of the problems associated with <br />the Safe Drinking Water Act are also increasing since many <br />rural areas are gaining from out-migration from urban areas. <br /> <br />Problem Area 5, ASA 1302 (Texas), 1303, and 1305. Flood <br />Problems and Hurricanes. <br /> <br />Flooding occurs when streamflow exceeds the channel <br />capacity. Historical1y,throughout the State of Texas, floods <br />have resulted in the loss of human life, as well as caused ser- <br />ious economic damages to urban areas, to agriculture, and to <br />transportation and utilities industries. Because of the wide <br />variations in climate and physiography of Texas, the magnitude <br />and character of floods differ widely, both within and among <br />the major river basins. <br /> <br />In the cen~ral and western portions of the Rio Grande in <br />Texas (ASA 1302, 1303, and the upper part of 1305), ground <br />and tree cover is sparse. Stream slopes vary from steep to <br />moderately steep. During periods of intense rainfall, runoff <br />is rapid, with high peak flows, high stream velocities and <br />shorter periods of land inundation. Flood frequency and esti- <br />mated damages are documented by the U.S. Corps of Engineers. <br /> <br />Estimated Flood Damages in the Rio Grande Basin in Texas <br /> <br /> Damage Dollars <br />Year Watershed Category (Value at time <br /> of Damage) <br />1950 Rio Grande (City of E1 Total $ 450,000 <br /> Paso <br />1954 Devi1's River (Cities of Agriculture 1,033,000 <br /> Ozona, Juno, Lake Walk Urban/Suburban 3,700,000 <br /> Other 866,000 <br />1955 Rio Grande (City of El Urban/Suburban 1,680,000 <br /> Paso (1972 dollars) <br /> <br />64 <br /> <br />., ",. , ~~ <br />, : . ," :..,.,) <br />'-" .......... <br />
