About the Mustang Bayou
Mustang Bayou crosses State Highway 6 near Alvin and runs southeast across the Brazoria County coastal prairie toward Chocolate Bay. It is the sort of water that sits in the middle of the fresh-to-salt gradient and refuses to commit to either end of it. At the gauge and above, it fishes as a freshwater bayou: largemouth bass, sunfish, catfish and gar in slow tannic water between grassy banks. Downstream, as it approaches the bay, the water turns brackish and the catch turns with it.
The gauge reports stage. On a prairie bayou this flat, stage responds to three separate things: rainfall over the watershed, tide pushing up from the bay, and wind stacking water in or pulling it out. None of them is reliably dominant, which makes the trace less straightforward to read than on a hill-country creek and means local knowledge counts for more than usual. The general rule holds, though, that a falling, clearing trace a day or two after rain is the best condition. A sustained onshore wind in late summer can hold the lower bayou high and salty for a week at a time, which changes what is catchable well above the bay.
What makes this bayou worth knowing is the overlap. In a dry summer with high salinity, redfish and flounder push a long way up, and it is entirely possible to take a largemouth bass and a redfish from the same stretch of bank within an hour. Access is from the highway crossing and the county road bridges along the course, and it is predominantly a bank and kayak fishery. Alvin is the nearest town with services, and Houston is close enough north to make this an easy half-day. Pressure is light for water this close to a major city, largely because most anglers passing through are on their way to the bay and never stop.

Access
Alvin - the town northwest of the crossing, with fuel, food, tackle and the nearest full services.
State Highway 6 bridge - the gauge crossing itself, with bank access on both sides and the obvious landmark.
County road crossings - the several bridges along the bayou's course, giving short stretches of bank access.
Chocolate Bay - the shallow bay the bayou eventually reaches, source of the flounder and redfish that run up.
West Galveston Bay - the larger bay system beyond, with the boat fishery this bayou's saltwater fish come from.
Hitchcock - the town southeast toward the bay, with additional access and launch options.
Houston - the city north, close enough to make this an easy half-day trip.
Seasons
Spring: the best freshwater window, with bass on the bank structure and sunfish spawning in the shallow margins.
Summer: warm and often low, with salinity climbing and redfish and flounder pushing up from the bay in dry years.
Fall: steadier water and the strongest overall fishing, with the flounder run bringing saltwater fish well upstream.
Winter: slow and weather-dependent, with catfish in the deeper bends and bass catchable on mild afternoons.
