What the Old Brazos River offers anglers
The Old Brazos River is a slower, meandering section of the Brazos that runs through Central Texas, primarily in Waller and Grimes counties between the main channel and oxbow lakes. It holds largemouth bass, catfish, and sunfish in a setting that feels removed from the faster current of the main river — the water moves gently through cypress-lined banks and shallow flats. Access is limited compared to the main Brazos, and much of the shoreline is private, which means you need to know where public entry points exist and what regulations apply before you fish.
The Old Brazos is not a destination for trophy hunting or high-volume catch days. It rewards patience and knowledge of structure — fallen timber, deeper holes, and the transition zones where the old channel meets backwater. The fishing is steadier in spring and fall when water temperatures favor active feeding, though catfish bite year-round in the deeper holes.
Key Takeaways
- Public access to the Old Brazos is limited; most entry points are private land or require permission, so scout access before planning a trip.
- Largemouth bass and catfish are the primary species, with bass favoring structure like fallen trees and deeper bends in spring and fall.
- Texas Parks and Wildlife regulations apply — you need a valid fishing license, and bass have a 14-inch minimum length limit with a five-fish daily bag.
- Water levels fluctuate with releases from upstream dams, so check current conditions before launching to avoid getting stranded.
- The Old Brazos is best fished from a small boat or canoe; wading is possible in shallow sections but requires knowledge of the bottom.
Access points and how to reach them
Public access to the Old Brazos is sparse. The most reliable entry is through private land where landowners permit fishing — this typically requires asking permission directly or knowing someone who has already established access. Some sections near Navasota have informal pull-offs along county roads, but these are not maintained public ramps and may be impassable after heavy rain.
The main Brazos River has more developed public access through parks and boat ramps, particularly near Bryan-College Station and downstream toward the Gulf. If you cannot locate safe access to the Old Brazos itself, fishing the main channel near the confluence points where the old channel rejoins is a practical alternative. Contact the Waller County Parks Department or local bait shops in Navasota for current information on where landowners are permitting access — this changes seasonally and year to year.
If you plan to launch a boat, bring a trailer suitable for rough ramps and shallow water. The Old Brazos has sections only 2 to 4 feet deep, so a shallow-draft boat or canoe works better than a deep-hulled center console. Launching at a main Brazos access point and paddling or motoring into the old channel is sometimes easier than finding a direct launch on the Old Brazos itself.
Bass fishing in the Old Brazos
Largemouth bass in the Old Brazos respond to the same structure-focused approach that works elsewhere in Texas — they hold tight to fallen timber, undercut banks, and the outside bends where the current (even slow current) scours deeper holes. Spring (March through May) and fall (September through November) are the most consistent seasons because water temperatures sit in the 65 to 75 degree range where bass feed actively throughout the day.
Summer fishing is possible but requires fishing early morning and late evening; midday heat pushes bass into the deepest available cover, which in the Old Brazos means the main channel holes and dense cypress root systems. Plastic worms, crankbaits that mimic shad, and topwater lures in low-light conditions all produce. The water is typically stained to muddy, so darker lure colors and those with vibration (rattles, vibrating jigs) outperform natural patterns.
Winter (December through February) slows the bite significantly, but catfish remain active. If you are targeting bass in winter, focus on the deepest holes and fish slowly — a jig-and-pig or a slow-rolling crankbait near the bottom will catch the few bass that feed during cold snaps.
Catfish and sunfish in slower water
Channel catfish and flathead catfish both inhabit the Old Brazos, and they bite consistently year-round in the deeper holes and along the main channel. Channel catfish respond to cut bait (shad, mullet, or chicken liver), live bluegill, and stink baits; flatheads prefer live bluegill or small shad and are most active at night. A simple three-way rig with a sinker and a circle hook works for both species in the slow current.
Sunfish — bluegill, redear sunfish, and longear sunfish — are abundant in the shallower sections and backwater areas. They bite readily on small jigs, inline spinners, and live crickets or worms. Sunfish are not the target for most anglers on the Old Brazos, but they provide consistent action for children or as a secondary species while waiting for bass or catfish to bite.
Water levels and seasonal conditions
The Brazos River system is managed by the Brazos River Authority, which operates dams upstream. Water releases from these dams affect the Old Brazos, particularly during spring runoff and after heavy rain. High water can make the old channel difficult to navigate and can push fish into the main channel; low water can strand boats and concentrate fish into deeper holes.
Before you fish, check the current water level and recent release schedule through the Brazos River Authority website or by calling their operations office. Local bait shops in Navasota or Bryan also track conditions and can tell you whether the Old Brazos is fishable on a given day. Spring (March through May) typically brings higher water; summer and fall are usually lower and more stable.
The Old Brazos is subject to flooding after heavy rain, particularly in the lower sections near the confluence with the main channel. If you leave a boat or vehicle at an access point, secure it well and be prepared for water to rise overnight.
Regulations and licensing
Texas Parks and Wildlife regulations apply to all fishing on the Old Brazos. You must have a valid Texas fishing license (available online through the TPWD website or at most bait shops). Largemouth bass have a 14-inch minimum length limit and a five-fish daily bag limit. Catfish have no minimum length but a 25-fish daily bag limit for channel catfish; flathead catfish have no bag limit. Sunfish have no minimum length and a 25-fish daily bag limit.
Trotlines and juglines are legal for catfish in Texas, but check current TPWD regulations for any seasonal restrictions or permit requirements specific to the Brazos system. Night fishing is permitted, which makes the Old Brazos attractive for catfish anglers targeting flatheads after dark.
Gear and tackle for the Old Brazos
A medium-power baitcasting or spinning rod (6 to 7 feet) works for both bass and catfish. For bass, 12 to 17-pound braided line or 12 to 15-pound monofilament handles the structure without excessive breakage. For catfish, 20 to 30-pound monofilament or braided line is more practical because catfish often run into heavy cover and require direct pressure to turn.
Bring a variety of lures: crankbaits in shad patterns, plastic worms in dark colors, topwater plugs for low-light conditions, and a selection of jigs and jig trailers. For catfish, a tackle box with circle hooks (2/0 to 8/0 depending on target size), three-way rigs, and a supply of cut bait or live bluegill covers most situations. A net, pliers, and a headlamp are essential; the Old Brazos has dense cover and low-light fishing is productive.
Frequently Asked Questions
Can I wade the Old Brazos?
Wading is possible in shallow sections, but the bottom is often soft mud and the water is stained, making it hard to see obstacles. If you wade, wear a life jacket, use a wading staff to probe ahead, and fish early morning when you can see the water better. Most anglers use a boat or canoe instead.
What is the best time of year to fish the Old Brazos?
Spring (March through May) and fall (September through November) are most consistent for bass because water temperatures favor active feeding. Catfish bite year-round, but summer and winter require more patience and specific techniques. Check water levels before you go — high water in spring can make access difficult.
Do I need a boat to fish the Old Brazos?
A boat or canoe gives you access to the best structure and deeper holes, but some sections near road crossings allow bank fishing. Access is limited, so scout the area first. Many anglers fish the main Brazos instead because public ramps are more developed.
What should I do if I get stranded by falling water?
Check the Brazos River Authority's water release schedule before you launch. If water drops while you are on the river, stay calm and pole or wade your boat to deeper water. Carry a phone with service and let someone know your planned return time. In an emergency, contact the Waller County Sheriff's Office.
Are there guides or outfitters for the Old Brazos?
Few guides specialize in the Old Brazos specifically because access is limited and the main Brazos is more popular. Local bait shops in Navasota can recommend anglers who know the water and may offer informal guidance. Your best resource is talking to other anglers who fish the area regularly.
