The public will be notified as soon as an exact date is determined. Due to the lake’s large watershed and giant salvinia’s rapid growth capability, the likelihood of an effective drawdown is reduced with a later start date. However, during the summer, salvinia growth is at its peak.
LDWF’s Lake Bistineau Waterbody Management Plan is designed to provide as much use of the lake as possible prior to water levels dropping. The water control structure is tentatively scheduled to be opened sometime between July 15 and July 31, 2019, depending on nuisance vegetation conditions on the lake. The drawdown will additionally benefit fisheries production by improving aquatic habitat and reducing the amount of organic matter on the lake bottom. Press release from Louisiana Wildlife and Fisheries: The Louisiana Department of Wildlife and Fisheries has scheduled a drawdown of Lake Bistineau in Webster, Bossier, and Bienville parishes for the purpose of reducing further expansion of giant salvinia.
