<br />:JO <br />[" <br />,- <br />....' <br />~ <br /> <br />The 1950 spring run-off into Lake Mead was considerably below <br />normal. Thus to guarantee water supplies for downstream irriga- <br />tion in current and future years, water releases for power produc- <br />tion were decreased from those of last year to assure some hold -over <br />storage. The generation schedule adopted at the beginning of the <br />year called for producing 4,416,000,000 kwh at transmission volt- <br />age. The project actually produced 4, 386, 293, 000 kwh as compared <br />to 6,036,830,000 kwh produced last year, a reduction of some 27%. <br />All water releases were passed through the power plant turbines. <br /> <br />Comparison with last year of the maximum usable storage con- <br />tent of Lake Mead follows: <br /> <br /> Maximum Date of Water <br />Operating Acre-Feet Maximum Surface <br />Year Stored Storage Elevation <br />1951 20, 862, 000 July 24, 1950 1,177.54 feet <br />1950 23,474,000 July 31, 1949 1,196.61 feet <br /> <br />Since the maximum usable storage capacity of Lake Mead <br />reservoir at elevation 1,229 feet is 29, 151, 928 Qcre-feet, approx- <br />imately 7.5 million acre-feet of the flood control reserve capacity <br />was not utilized this year, as compared to some 5 million acre-feet <br />last year. <br /> <br />Comparison with last year of the minimum usable storage <br />content of the lake follows: <br /> <br /> Minimum Date of Water <br />Operating Acre-Feet Minimum Surface <br />Year Stored Storage Elevation <br />1951 16,483,000 May 11, 1951 1,141. 19 feet <br />1950 17,477,000 April 13, 1950 1, 150 feet (approx.' <br /> <br />Wale", $<<1JfJ4 <br />e~~ ami <br />tl/ed ()H <br />VJIood e()Ht~ <br />ami fJlJ4dudioH <br /> <br />11 <br /> <br />--_.,._~~.._~..........,<~~--=--= .. - _.~ <br />
