The probability of the historical data indicates the percent of time the lake elevation would be in each zone. Each agency having responsibilities on the lake would develop their planning and management activities for each of the seven four- foot zones. The information would be assembled by zone to provide plans and management options for a full range of lake levels. A general description of each zone is given below. Zone 1. Elevation 4188- 4192 feet. The probability analysis indicates the lake would be in this zone about 1.4 percent of the time. Historically the lake was in this zone during the low levels in 1961, 1962 and 1963. While in this zone, the lake would be characterized with an average surface area and volume of 564,200 acres and 7,868,300 acre- feet, respectively. Access to the lake would be extremely limited for recreational and industrial purposes. A vast mudflat would be exposed around the lake. Managed wildlife areas around the lake may continue to operate, but other wildlife habitat may be severely impacted in this zone. These low lake levels and high salinity may either help or hurt mineral industries, depending on their location and salts they are harvesting. The salinity of the lake would be at saturation ( 27 percent salt by weight) in the north arm of the lake and would vary from about 24 percent 27 |
