About Grand Bayou Reservoir
Grand Bayou Reservoir covers a stretch of water in Louisiana and is classed as a reservoir.
We read the level from USGS gauge 07352820, listed as Grand Bayou Reservoir at spillway nr Coushatta, LA. Wind and weather come from the National Weather Service grid cell over the lake, so the numbers describe open water rather than the nearest airport.
Reservoir levels move with releases and inflow, so ramps and beaches can change week to week. The water level page tracks that day by day.
The go or no-go calls above are a starting point, not a guarantee. Read how we score conditions, and always check local rules and posted warnings before you launch.
