Post-spawn bass active on Hill Country lakes as Memorial Day arrives

What's Biting

What's Next

**The next 48 to 72 hours**

With the First Quarter moon overhead, solunar activity on freshwater reservoirs tends to favor mid-morning and late afternoon feeding windows. For Travis, LBJ, and Buchanan, the practical takeaway: be on the water before 7 a.m. or after 6 p.m. Wired 2 Fish confirms post-spawn bass are at their most aggressive during low-light conditions when calm surface water lets topwater presentations work effectively. Hollow-body frogs, walk-the-dog plugs, and poppers near shallow timber and grass edges are worth targeting through the first hour of daylight.

**What should turn on soon**

As surface temps push into the upper 70s and low 80s, typical for late May on these reservoirs, fish will abandon mid-lake flats during peak heat and stack on structure. Creek channel drop-offs, submerged timber on the upper arms of Buchanan and LBJ, and mid-lake humps on Travis become productive mid-morning through early afternoon. Striped bass, which suspend in the water column rather than hugging the bottom, should be locatable on sonar over main-lake structure as bait schools condense. A mid-depth swimbait worked through the bait zone is the standard approach when fish are marking but not committing to the surface.

Guadalupe bass, Texas's native state fish and a resident of the Highland Lakes' rocky creek arms, tend to stage along current-swept rocky points and tributary mouths in late May. With Colorado River inflow running at a steady 372 cfs per USGS gauge 08158000, there should be enough current in the upper sections of Travis to activate feeding lies near rocky structure. Small finesse swimbaits and inline spinners worked tight to the bank are the go-to presentation for this species.

**Memorial Day weekend timing**

Heavy recreational traffic is all but guaranteed Saturday and Sunday. Wakes and noise will scatter shallow fish earlier than usual. Adjust your topwater window to pre-dawn if possible, then shift to deeper mid-lake structure by 9 a.m. The upper reaches of Buchanan, which see less recreational pressure than the lower chain lakes, may hold more consistent mid-morning action. My Canyon Lake Fishing confirms ramp access across the hill country region is fully operational heading into the holiday.

Context

Late May on the Highland Lakes chain, Travis, LBJ, and Buchanan, typically marks the end of the spawn and the beginning of the summer transition, one of the most productive stretches on the Texas calendar before intense heat locks fish into the deep thermocline. In a typical year, largemouth bass in these lower-elevation central Texas reservoirs complete bed activity by mid-month and enter an aggressive post-spawn feeding phase during the third and fourth weeks of May, which is exactly the window we are in now.

No comparative seasonal benchmark from a state agency is available in the current data feeds, making it difficult to gauge precisely how this year's season stacks up against historical norms.

What the available data does suggest is mildly encouraging. The Colorado River inflow at USGS gauge 08158000 is running 372 cfs, a moderate unflooded level consistent with late-spring conditions rather than the drought-stress lows that have affected these reservoirs in recent dry years. My Canyon Lake Fishing notes that Canyon Lake, in the nearby Guadalupe watershed, is sitting eight feet higher than this time last year, suggesting the Edwards Plateau received meaningful spring precipitation. If similar dynamics extend to the upper Highland Lakes, Buchanan and LBJ may be at or above recent pool averages heading into summer, a condition that historically pushes bass into newly flooded shoreline cover and timber, expanding productive habitat.

For anglers who fish these lakes year to year, the Memorial Day window has a well-earned reputation as a brief sweet spot: fish are hungry, water temps have not yet crossed the threshold that triggers full summer lockdown, and the post-spawn feeding windows are predictable. It is typically the last reliable week of consistent shallow-water bass action before the dog days arrive.
