About the Bayou Manchac
Bayou Manchac runs east from the Mississippi River batture near Baton Rouge to the Amite River, and it carries more history than almost any water its size in the state. It was once a navigable distributary of the Mississippi and served as an international boundary in the eighteenth century, when it separated British West Florida from Spanish Louisiana. The head was closed off from the Mississippi long ago, so what remains is a slow drainage channel fed by runoff and backwater rather than by the big river.
Hydrologically it behaves like a long shallow slough. Current is weak and frequently reverses, because the lower end is influenced by stage on the Amite and, beyond that, by tide in Lake Maurepas. Water is usually stained, the bottom is soft, and cypress, willow and laydown timber line much of the bank. After heavy rain the whole system rises quickly and pushes fish into the flooded edges, then drains back over several days.
The fishing is classic slow water bayou fishing. Largemouth bass hold against laydowns and the cypress knees and take soft plastics and spinnerbaits worked slowly. Bluegill and redear sunfish are dense and are the most reliable target for anyone fishing simply, particularly around the cypress in late spring. Channel and blue catfish use the deeper sections of the channel, and bowfin and spotted gar are common, strong and worth catching on purpose rather than treating as a nuisance.
Access is better than it used to be. Bayou Manchac Park on the East Baton Rouge side provides public frontage and a launch suited to kayaks and small boats, and the Alligator Bayou area at the western end reaches the connected wetlands. The bayou is narrow and often obstructed, so a kayak or a small jon boat is the right craft. Much of the bank away from the parks is private, and the water is the practical right of way.
Time of year matters more than technique. Spring is the strongest period, with bass on the shallow cover and bream bedding around the cypress. Summer is hot, low and often oxygen poor in the backwaters, so the main channel fishes better than the sloughs. Fall cools things off and improves the bass bite again. Winter concentrates fish in the deeper holes and is the best catfish period of the year.
