<br />11ater Supply.--II/ater supply and operation studies for the Savery-Pothook Project
<br />
<br />were made for the 24-year period 1929 throuph 1952. Durinp: this ti~e the water
<br />
<br />supply with the project constructed would very nearly be adequate to meet require-
<br />
<br />ments as indicated. An averap:e irrigation shortage of 4.2 percent of demand would
<br />
<br />occur. This shortage results from shortapes of a much more substantial nature in
<br />
<br />several years, and no shortage in several other years, Rather serious shortages
<br />
<br />would have occurred in three years, 1934, 1936, and 1940, with the shortages being
<br />
<br />51, 10, and 23 percent, respectively. Lesser shortages ranying from one to five
<br />
<br />percent would have occurred in 1939, 1941, 1943, and 1944. II/hen the water-supply
<br />
<br />studies were extended five additional years to 1957, an additional year of shortage
<br />8/
<br />(about 10 percent) occurred in 1955.-
<br />
<br />If water-supply studies were extended through 1963, it is quite likely that
<br />
<br />additional shortages would be revealed. The frequency of rather severe water
