Catfishing the San Antonio River (Urban River) – practical guide for early fall
-
Seasonal snapshot (early fall): Current conditions in San Antonio show clear skies and comfortable temps around 75.9 °F with light winds (about 6.5 mph). Water temps are still warm enough to keep catfish active, but as evenings cool, feeding often picks up after sunset. Plan dawn or dusk sessions, and don’t neglect after-dark bites when air temps drop a bit. Weather calmness and clear water can mean longer, slower presentations, so be ready for longer waits between bites.
-
Where to fish it (San Antonio River): Look for current seams and depth changes near bridges, bends, and downstream eddies. Catfish love structure, so cast along under bridges, near fallen timber, and in deeper pools just off the main current. Quiet side channels and pockets behind pilings can hold holdover fish that cruise the river for an easy meal.

Bait, rigs, and tackle for river cats:
- Bait ideas: fresh-cut fish (shad, carp), chicken liver, or stink/punch baits are classics here. Live bait (small sunfish) can outfish cut bait in slow-water pockets.
- Rig options:
- Classic bottom rig: 2–3 oz slip sinker on the mainline, a 12–18 in fluorocarbon leader, and a circle hook in the 2/0–4/0 range. This works well for cut and stink baits.
- For snag-prone river banks, try a line-value Setup with a slightly heavier weight and a swiveld leader to reduce line twist when snagged.
- Tackle tips: use 15–30 lb mainline for strength and abrasion resistance; add a 12–18 in leader if you’re fishing near structure. A simple two-rod approach works on public banks where allowed; otherwise, keep it simple and patient.
-
Techniques that work here:
- Dead-sticking (let the bait sit on the bottom and watch the line for subtle takes) when water is clear and fish are picky.
- Night fishing with a gentle glow from a headlamp can dramatically improve bites as temps drop and cats get active again.
- Cast-and-wait: cast upstream slightly and let the bait drift naturally toward structure; sometimes the strike comes as the current diverts the bait toward a snag or undercuts.
-
Lures as a backup option:
- If the bite is slow, heavy swimbaits or large spoons can trigger curious cats or blues that cruise the river. See options like slow-sinking swimbaits and big rattling spoons as backups when bait is ignored.
-
Weather and river tips (early fall context):
- With clear days and moderate humidity, fish biomass remains active but bite windows tighten to cooler parts of the day and after dark. If a front passes and water gets murkier, switch to scent-based baits and stay patient.
-
Regulations and safety:
- Always check Texas freshwater regulations and daily bag limits for catfish before fishing urban rivers. Wear a PFD when wading or fishing from banks, and stay mindful of water levels after rain.

Bottom line: You’re in an urban river system with reliable catfish potential, especially during early fall’s comfortable temps. Go prepared, cast near structure, stay patient, and mix live bait with a sturdy bottom rig. You’ll likely hear that telltale lull followed by a strong bite as the river cools—then it’s on. Tight lines, and welcome to San Antonio’s river catfishing scene! 🐟💥
