Show available gauge reading March 1 1947 showed the lake below n0" but 55 feet above the level for the sane period of 1946 14 study of ten selected stations on the Wasatch Front shows that during the ten year period since 1936 the average precipitation has been approximately 8$ above average for A stations over the thirty-fiv-e year period 1898- 3 1932 5 Hence a rather close correlation between precipitation and lake oscillation is demonstrated In spite of the 1941-4- 6 gradual rise of the lake the writer sees little prospect that it will reach its high levels of the 1870’s or even the 1920 ’s Of course a radical change in climatic conditions could bring this about However past history has shown that rise and fall follow relatively definite cycles of approximately ten years duration each If this pattern is repeated again the lake may soon be expected to come to the end of its present cycle of rise With the increase in capacity of the various irrigation storage reservoirs virtually the only water of any real significance that reaches the lake is that of spring flood waters In relatively dry seasons these reservoirs the same are almost completely drained 14 Letter from M T requiring practically all Wilson Geological Survey March 4 1947 15 See Table III p 273 Salt Lake District Manager |
