About the Bastrop Bayou
Bastrop Bayou drains the flat coastal prairie of Brazoria County and empties into Bastrop Bay, one of the shallow back bays behind Galveston Island’s southern end. It is a modest water body by length but a productive one, and it belongs to the band of Texas coastal bayous that fish far better than their appearance from a road crossing would suggest. The gauge at County Road 288 reports stage, which is the number that matters on a bayou whose level is governed by tide and rainfall rather than by any upstream release.
The bayou divides naturally into two fisheries. The lower reach, from the bay up through the marsh, is tidal and brackish, and it holds redfish, speckled trout, flounder, black drum and sheepshead moving with the tide through the grass edges and the drains. This is shallow-water fishing, often done from a skiff or by wading, and it rewards anglers who read a tide line and a mud boil. The upper reach runs fresher, tannic and narrow between prairie and woodlot, and there largemouth bass, bluegill and catfish take over.
Bottom is soft coastal mud and shell, with oyster reef appearing toward the bay. Marsh grass, cordgrass edges and the mouths of small drains concentrate bait, and that is where fish set up. Wind matters enormously because the water is shallow and colors up fast, and a hard southeast blow can turn a clear grass edge into chocolate in a single afternoon.
Much of the surrounding marsh sits inside or adjacent to Brazoria National Wildlife Refuge, which keeps development modest and the habitat intact, and the refuge lands also open a good deal of the surrounding prairie and marsh to walk in anglers willing to cover ground.
Access runs through Angleton and Lake Jackson, with public ramps on the bay side and road crossings upstream.

Seasons
Spring: redfish and trout move up with warming tides and bass spawn in the fresher upper reaches.
Summer: hot and often calm early, with trout on the grass edges and flounder in the drains.
Fall: the best month range on this coast, as flounder run for the passes and redfish school heavily.
Winter: cold fronts push water out and fish deep, with redfish and black drum the steadiest targets.
