Show more than 10 billion kilowatt-hours in the year end- ing June 30, 1945. The tabulation below shows present capacity of the TVA system, including the Alcoa and Cumber- land plants on the Cumberland River. Table 3 indicates the ultimate capacity at individual exist- ing plants. The aggregate total will ultimately be nearly 4 million kilowatts.

Source: Tennessee Valley Authority. Water Supply There are 262 public water supplies in the Tennessee River Basin, serving a population of about 850,000 as well as associated industries. Ap- proximately one-third of these supplies, serving a population in excess of 650,000, obtain water from surface so-urces. Only 8 cities with populations over 5,000> obtain their sources from ground water alone. Large ground water supplies are generally limited to the western part of the basin, which is predominantly agricultural. Industri s\ water needs in the basin are larger than domestic requirements. While much of the water used by industry is for cooling purposes, sizable quantities, frequently involving higher quality, are required in manufacturing processes. Industrial needs have been growing during the last two decades as textile, chemical, pulp and paper, and food- processing plants have increased or expanded in the valley. The present population and industrial growth indicate an increasing demand for public and in- dustrial water supply. Although the quantity of surface water available for industrial and public needs in the basin is generally adequate, the quality of surface waters is being damaged by the increasing discharge of industrial and municipal wastes into the streams. Municipal and industrial pollution causes exten- sive damage to public and industrial water supplies. The damage includes bacterial pollution, offensive taste, color, odor, and increased hardness. Water resources developments for other purposes have had both beneficial and detrimental effects on water supplies. Generally, except for direct dam- ages to plants or intakes, the effects are beneficial. An exception was the reversal of flow in the Emory River due to temperature changes caused by releases from Norris Reservoir, which resulted in contami- nated water being carried to the water intake for the city of Harriman. Reduction in the fluctuations of flow and improvements in water quality are gen- erally regarded as beneficial. Federal river development in the basin has not had municipal water supply as one of its purposes, although reservoir construction has improved the supply for adjacent areas. Generally, provision for water supply is recognized as a community re- sponsibility, the Federal interest in municipal water supply being expressed through the Public Health Service and TVA acting in an advisory capacity. Malaria Control Malaria in the Southern States has long been a severe drain upon the health and vitality of the region. Malaria is especially prevalent in the South because of the frequent rains, the many swamps and lowlands, the number of sluggish streams, and the high temperatures. Although malaria is endemic throughout the South, deaths from the disease are most frequent in the broad flats along the lower reaches of sluggish rivers. The most important of all these is the flood plain of the lower Mississippi, extending up the valleys of its tribu- taries, including the Tennessee. 728 |
