About the Dickinson Bayou
Dickinson Bayou runs east across Galveston County from the prairie near Alvin to Dickinson Bay and the western side of Galveston Bay. It is short, it is shallow, and it is tidal for a great deal of its length, which makes it one of the more accessible pieces of genuine bay fishing available without a boat capable of crossing open water. The upper reach near the FM 517 gauge is fresh, the lower reach is brackish, and the boundary moves with weather.
The lower bayou is the draw. Redfish use the shorelines, the marsh drains and the shell along the deeper bends, and they are catchable year round with the best fishing on a moving tide. Spotted seatrout push up the bayou when salinity allows, particularly in the cooler months, and hold over the deeper holes. Southern flounder stage at the creek mouths and cuts and are the fall target. Black drum work the shell and the bridge pilings.
The upper reach is a different fishery. Above the salt line it is a stained freshwater bayou with laydown timber and cut banks holding largemouth bass, bluegill and channel catfish. Alligator gar are present throughout and reach substantial size in the deeper middle sections. After a heavy rain the fresh water pushes far down the bayou and the whole fishery slides toward the bay for a week or two, which is the single most useful thing to know before making the drive.
Access is unusually good. Public ramps and park frontage serve the bayou in Dickinson and along the lower reach, the farm road crossings give bank and kayak access through the middle, and the bayou is narrow enough that a kayak is a genuinely competitive way to fish it. Paul Hopkins Park and the county frontage provide reliable public water, which is worth knowing in a part of Texas where bank access is often the limiting factor.
Seasonally, fall is the best period, with the flounder run through the lower bayou and redfish feeding hard ahead of winter. Spring is strong for trout and for bass in the upper reach. Summer is hot and the lower bayou can go low in oxygen in the back sloughs, so the main channel and the moving tide matter more. Winter concentrates trout and redfish in the deeper holes and fishes well on warm afternoons.
