Texas Freshwater at 78°F: Catfish Hot, Post-Spawn Bass Going Deep
USGS gauge 08211200 recorded 78°F water and a moderate 41.3 cfs flow as of May 2 — warm enough to push Texas freshwater fishing squarely into early-summer patterns. Largemouth bass have largely completed their spawn at this temperature and are transitioning into post-spawn recovery, typically pulling back from shallow flats toward deeper adjacent structure and feeding more selectively. Catfish, by contrast, are in prime feeding mode as water climbs through the 75–80°F band. No Texas-specific charter, tackle shop, or agency reports came through in this cycle's angler-intel feed, so species outlooks here reflect seasonal baseline expectations rather than fresh on-water testimony. Worth flagging: Wired 2 Fish reports that crappie are staging heavily and generating heavyweight limits on comparable Southern reservoirs this week — similar conditions are typical on Texas impoundments at the full moon in early May, though local verification is always the smart move.

What's Biting
Largemouth Bass
finesse rigs near post-spawn cover, 6–12 ft depth
Crappie
deep brushpiles post-spawn with forward-facing sonar
Catfish
cut bait or live perch in river holes after dark
White Bass
spring tailwater run typically concluding by early May
What's Next
With water temps already at 78°F on May 2 and the full moon cresting tonight, the next 48–72 hours represent a transition window rather than a peak moment for most species — but catfish and post-spawn crappie are the clear exceptions.
**Catfish** are the strongest play right now. Flatheads and channel cats feed most aggressively once water clears 70°F, and the low, stable flow of 41.3 cfs at USGS gauge 08211200 suggests clear-to-lightly-stained conditions — ideal for fishing cut bait or live perch in deeper river holes and reservoir ledges. The full moon extends feeding windows well into the night; plan for an evening launch and fish through the dark hours for the best shot at a quality fish.
**Largemouth bass** in post-spawn mode are typically scattered and recovering near their spawning flats — laydowns, dock pilings, and submerged grass edges in the 6–12 foot range are reliable starting points. Reaction baits can trigger neutral fish, but slower finesse presentations tend to be more consistent this time of year when fish aren't chasing aggressively. Morning and evening windows remain most productive as midday heat climbs.
**Crappie** at 78°F have likely pushed through or are wrapping up their spawn. Post-spawn fish scatter to brushpiles and submerged timber in 10–15 feet of water. Wired 2 Fish reported this week that anglers on comparable Southern reservoirs are slamming heavyweight limits using forward-facing sonar over deep structure — a tactic worth applying on Texas impoundments with established brush piles. Early morning hours give the edge before boat traffic picks up.
Looking further out: as May deepens and surface temps edge toward the low 80s°F, topwater action on bass will improve. Early-morning poppers and walking baits become very productive once post-spawn fish begin actively chasing shad. Watch local shad spawn activity as your trigger — when bait is visibly flipping on the surface at dawn, topwater is the call.

Context
Early May in Texas typically marks the hard turn from spring spawn mode into early-summer holding patterns, and the 78°F reading from USGS gauge 08211200 is consistent with that timeline. On central and south Texas reservoirs, largemouth bass generally spawn from mid-March through April as water temperatures pass through the 62–72°F band. By the time temps climb into the upper 70s, most fish have completed spawning and shifted into recovery — meaning this week sits right at the expected post-spawn transition.
Crappie spawn timing aligns similarly in this region: fish typically move shallow in April and early May when water reaches the 60–68°F range. At 78°F on May 2, any lingering spawn activity should be wrapping up, and the population transitions to summer staging depths over the coming weeks. The full moon on May 2 is consistent with a final push of late spawners, which tracks with Wired 2 Fish's reporting this week of heavy crappie activity on Southern reservoirs during late-stage staging.
Catfish enter their most aggressive feeding window in Texas once water consistently exceeds 70°F, typically running strong from late April through June. The current reading sits squarely in that zone.
Flow at 41.3 cfs is a modest reading for a Texas river gauge in early May. Without multi-year comparison data for this specific site, characterizing it as above or below average is speculative — but a low, stable flow generally favors clear-water presentations and structure fishing over broad reaction-bait searches.
No Texas-specific comparative season reports appeared in this cycle's angler-intel feeds, so the context above draws on regional seasonal baselines rather than current on-water testimony. Conditions can vary significantly between east Texas timber impoundments and the hill country reservoirs or south Texas river systems — local tackle shops remain the fastest way to get targeted intel before you head out.
