Lake Bistineau drawdown announced
A drawdown of Lake Bistineau has been scheduled
to begin May 1 for giant salvinia control, organic reduction and fish habitat
improvement, according to an announcement by the state Department of Wildlife
and Fisheries (LDWF).
Summertime temperatures promote maximum growth
of the salvinia and the drawdown is designed to reduce further expansion of the
pesky plant. Giant salvinia is growing rapidly on the lake despite efforts by
LDWF contractors who have treated more than 5,000 acres since Feb. 20.
LDWF officials estimate the plant covers 3,349
acres of the lake based on an aerial survey conduced March 23. Spray efforts
are ongoing in areas of the lake that will not lose water during the drawdown.
Intensive herbicide applications will continue during the drawdown.
Bistineau should drop at a rate of four to six
inches per day and the lake will be lowered to a maximum drawdown level of
eight feet below normal pool state. The control gates are scheduled to close on
Nov. 30 to allow the lake to refill for winter and early spring recreational
During the drawdown an estimated 10,000 acres
of water will remain in the lake. Boaters will be able to access the lake at
Port of Bistineau public boat launch, the Bossier Parish public launch, Grice’s
and Bayou Dorcheat public launch.
Boat lanes on the lake will not provide normal
clearance of underwater obstructions during the low water period and boaters
are urged to use caution.
Officials said the drawdown is a necessary
component of the LDWF integrated management plan to control overabundant
aquatic vegetation growth and to improve sport fishing on Lake Bistineau. An
annual cycle of high and low water fluctuation can provide beneficial effects
similar to a natural overflow lake system.
