Louisiana Department of Wildlife and Fisheries (LDWF) has requested the Department of Transportation and Development close the Lake Bistineau water control structure on or about November 20 in order to conclude this year’s drawdown. The drawdown, which began July 31, was conducted to control the expansion of the invasive aquatic plant Giant Salvinia.
The drawdown is a necessary component of LDWF’s integrated management plan to control overabundant aquatic vegetation growth to improve Lake Bistineau sport fishery.
An annual cycle of high and low water fluctuation can provide beneficial effects similar to a natural overflow lake system.
Closing the gates at this time should allow the lake to reach full pool stage for traditional recreational activities in the spring.
