Show salt by weight of saturation in the south arm of the lake. Vast amounts of salts would precipitate and collect on the bottom of the lake. Zone 2. Elevation 4192- 4196 feet. The lake probability analysis indicates this would be in this zone 7.6 percent of the time. Historically, the lake was in this zone briefly in 1902, and from 1934 to 1946 ( except 1937 to 1939 and 1943 to 1945, when the highs exceeded 4206), and from 1960 to 1968. While in this zone, the lake would be characterized with an average surface area and volume of 677,900 acres and 10,301,100 acre- feet, respectively. Access to the lake would still be difficult for recreational and industrial purposes because of extended mudflat areas and low lake elevations. The salinity of the lake would range from 17 to 24 percent salt by weight in the south arm but would be at saturation in the north arm. Large amounts of salts would be precipitated in the north arm of the lake while in this zone. Zone 3. Elevation 4196- 4200 feet. The probability analysis indicates the lake would be in this zone about 23 percent of the time. Historically, the lake was in this zone from 1902 to 1906, from 1932 to 1939, from 1942 to 1951, from 1954 to 1959 and from 1969 to 1972. While in this zone, the lake would be characterized with an average surface area and volume of 890,000 acres and 13,422,000 acre- feet, respectively. Access to the lake should range from a problem at the lower part of the zone to a more normal nature in the rest of the zone. The salinity of the lake would range from about 12 to 17 percent salt by weight in the south arm and 24 percent to saturation in the north arm. Salts would begin precipitating in the north arm of the lake in the upper part of this zone and build up to large amounts as the lake level approached the lower part o the zone. Zone 4. Elevation 4200- 4204 feet. The probability analysis indicates the lake would be in this zone about 33 percent of the time. The 1851 to 1994 average ( south arm) level of the lake is 4201.3 feet. Historically, the lake was in this zone from 1851 to 1853, from 1858 to 1863, from 1891 to 1901, from 1907 to 1921, from 1927 to 1931, from 1952 to 1953, from 1973 to 1982, and from 1991 to 1994. While in this zone, the lake would be characterized with an average surface area and volume of 1,175,000 acres and 17,641,000 acre- feet, respectively. Access to the lake would be good in the lower part of the zone but may start to be a problem in the upper part of the zone due to the high nature of the lake. Recreation, wildlife and other activities/ facilities that operate close to the lake have experienced some flooding/ damage in this zone. The salinity of the lake would range from about 9 to 12 percent salt by weight in the south arm and 20 to 24 percent salt by weight in the north arm. Zone 5. Elevation 4204- 4208 feet. The probability analysis indicates the lake would be in this zone about 25 percent of the time. Historically, the lake was in this zone from 1863 to 1866, from 1880 to 1890, from 1922 to 1926, 1983, and from 1989 to 1990. While in this zone, the lake would be characterized with an average surface area and volume of 1,330,000 acres and 22,541,900 acre- feet respectively. This zone should also be characterized as the zone where major flooding and 28 |
