About the Chocolate Bayou
Chocolate Bayou rises on the coastal prairie south of Alvin and runs southeast to Chocolate Bay, a shallow arm of the upper Texas coast system behind West Galveston Bay. The name describes the water honestly, which is a fair introduction to a bayou that is more productive than it is pretty. The gauge near Alvin reports both discharge and stage, and it is one of the few bayous in this set where a real flow number is available, because this upper reach still behaves like a prairie stream rather than a tidal channel.
The bayou changes character along its length. Above the tidal influence it is fresh, narrow and often slow, running between prairie and scattered woodlot, and it holds largemouth bass, bluegill, catfish and gar. As it drops toward the coast the channel widens, salt works in, and the fishery shifts to redfish, speckled trout, flounder, black drum and sheepshead. The transition zone moves upstream and down with rainfall and tide, and the most interesting fishing is often found right where the two fisheries overlap.
Structure is bank wood, cut banks, shell in the lower reaches and the mouths of drains and cuts through the marsh grass. Bottom is the soft mud the bayou is named for. Wind and rain both change conditions quickly, and the discharge reading is genuinely useful for judging how much fresh water has pushed the salt line down, which in turn tells an angler whether to rig for bass or for redfish before leaving the house.
Industrial development sits near the lower bayou, but the marsh between the highway and the bay remains largely intact and fishes well.
Access runs through Alvin and the bay side ramps, and the bayou is small enough through its middle reach that a kayak is often the most practical boat.

Seasons
Spring: warming water brings bass onto shallow spawning flats and redfish up into the lower bayou.
Summer: trout work the lower grass edges, while the fresher upper reach fishes best at first light.
Fall: flounder run toward the bay and redfish school, making this the strongest season.
Winter: fronts drop levels and fish stack in the deeper channel bends, with drum most reliable.
