A crisp, open sky after dark, with a kind N breeze on the water and the barometer heading up. Most of the action on Grand Bay should come off banks where bait gets pushed by the flow. The forecast backs the stretch from the day. Ride the conditions while they last. Cooling water has fish active and on the move.

Grand Bay falls in Concordia Parish, part of Louisiana. It sits at 46 feet above sea level. At about 153 acres, a day is enough to walk the shoreline properly. The bank runs about 2.0 miles all the way round, so one visit can cover most of it. For supplies, Simmesport is 9.3 miles out. For a city, Baton Rouge is 53 miles off. The boundary is close enough to be worth checking before you fish.
Our records hold no depth for this water. Look for the band where the shallows give up and the bottom falls away. Read the surface for the wind lane, then fish the edge of it. Public wildlife records from this area list flathead catfish, black carp, silver carp and bighead carp. The list reflects reported sightings and surveys rather than what is stocked. On Grand Bay the quiet end is the one worth the extra effort.
In an average year July sits at 82°F and January at 48°F. The year never really closes; it just gets uncomfortable in summer. March through May is the strongest run, with autumn a second stretch. Autumn steadies things again once the heat lets go. Keep it in mind when planning a trip to Grand Bay.
We have no record of the rules that apply on this bank. Records list it as a natural water body rather than an impoundment. Public mapping records no formal access here, so plan for a walk and soft ground. For the catfish, fish bottom baits into the deeper holes and let them sit. A phone call first saves an afternoon. Where parking is tight, arriving early solves most problems. Moreau Lake at 0.9 miles is the sensible second choice. Nothing on Grand Bay should be assumed from this page alone.
