SJRWMD lowering Lake Griffin for dam maintenance
The St. Johns River Water Management District (SJRWMD) is beginning to lower the water level of Lake Griffin to the minimum desirable level for the Moss Bluff Dam rehabilitation work.
The plan is to soon start discharging water at a rate of 150 cubic feet/second at the dam to gradually lower the lake water level by mid-April. Some water will be let into Emeralda Marsh Area 3 to raise it to lake level in preparation for later reconnection to the lake. The current lake level is 57.64 ft. and the target elevation is 56.96 ft., so the water level will be reduced by 0.68 ft. Construction is expected to last into mid-summer, when the lake level should recover during the typical rainy season.
