Short answer: For rat (topwater rat) fishing in San Antonio, your best bets are the urban ponds and slow-moving sections of the San Antonio River plus small lakes with docks, grass and flooded timber. Think: Lake Calaveras, Woodlawn Lake, and stretches of the San Antonio River (River Walk / Confluence / Concepcion Park) — these hold hungry largemouths that love a noisy surface rat when conditions are right. 🐀🎣
Where to focus and why
- San Antonio River – Riverwalk / Confluence / Concepcion Park: lots of docks, overhanging brush and pocket water. Great for rat-l-trap style topwaters where bass key on bait pushed into tight cover. See city fishing action: Fishing The San Antonio Riverwalk (CITY FISHING).
- Lake Calaveras, San Antonio, Texas: good shoreline structure, docks and shallow humps — classic rat country when fish are shallow. (Video recon: lake calaveras san antonio tx).
- Woodlawn Lake, San Antonio, Texas: urban pond with cover and a lot of pressured fish — topwater rat bites can be explosive in the low-light windows. Urban spot rundown: Urban Fishing in Downtown San Antonio.

Tackle & lure picks
- Use a heavy fast-action rod (7’+), baitcaster, 50–65 lb braid with a 20–30 lb fluorocarbon leader (or straight braid if you prefer). This gives you hookset power and the backbone to slap fish off docks.
- Topwater rats and rat-style wake baits in natural or black/blue patterns shine here — consider the local favorites on Tackle.net: Rocker Rat (Pearl White) or Chocolate Swimbaits "The Rat". If you want a bigger kit, try a curated lure box like the Rapala Bass Boom Box on Amazon.
Techniques & timing
- Fish low light (dawn/dusk) or the warmest part of the day in early winter — bass will be sluggish otherwise. With current weather around 64°F and clear skies, target sunny shorelines and pockets that warm during midday; wind ~11 mph can help push bait into cover — fish the wind-blown side.
- Retrieve: walk, twitch, pause, then strip — vary cadence. In colder water slow things down: longer pauses and subtle twitches. Hit docks, riprap, lily edges and flooded brush; work the seams and the edges where deep meets shallow.
Practical tips
- Use strong, sharp hooks; replace trebles with big singles for better hookups around heavy cover.
- Scout from shore first — find structure and current seams, then cast tight to cover.
- Respect private property and local regs; many urban spots allow shore fishing but check signs.
Get out there and make some noise — a well-placed rat can produce some of the wildest topwater strikes in town. Tight lines and big splashes! 🐟🔥
