Water Level Fluctuation--It's Effects on Vegetation Control and Fish Population Management
The fluctuation of water level as a lake management practice in Louisiana is explained using three lakes as examples. These lakes vary from 1,000 to 2,600 acres and are scattered over the state. Anacoco Lake, a 2,600 acre impoundment in central Louisiana, was fluctuated primarily for aquatic vegetation control. The vegetation was reduced 90% over a period of three years.
