Hill Country Post-Spawn: Bass on Top, Crappie Firing Strong

What's Biting

What's Next

The New Moon this weekend removes lunar surface light at dawn and dusk — historically the prime windows for topwater largemouth on all three Hill Country lakes. With Tactical Bassin reporting the bluegill spawn at or near its peak across the region, focus the next two to three mornings on shallow, sun-warmed flats and rocky points in two to four feet of water. Look for pale, fanned circles on gravel substrate where bluegill have cleared beds; largemouth will be patrolling the edges. A hollow-body frog worked through emergent cedar branches and over matted vegetation is the highest-percentage opener; when topwater action cools by mid-morning, Tactical Bassin's post-spawn transition coverage points to soft-plastic swimbaits and chatterbaits along the first depth break as the next reliable option.

Striper anglers on Buchanan should expect fish to push deeper as the sun climbs. Temperatures on the Highland Lakes are typically tracking the mid-to-upper 70s °F by the third week of May — still within striper comfort range but beginning to shove fish toward cooler thermocline water by late morning. Troll deep-diving shad imitations or present live shad on main-lake humps and channel edges in the 15–25 foot window. In the absence of local charter reports this week, lean on your sonar: baitfish marks are the most reliable real-time depth indicator on these open-water reservoirs.

LakeForkGuy's post-spawn crappie coverage describes fish staging near submerged timber and dock pilings at transitional depths right now. That habitat description fits the brush-heavy coves of Travis and the timber-lined arms of LBJ particularly well. A 1/16 oz jig in chartreuse or white on light spinning gear, fished at six to twelve feet, should produce throughout the day; the dark New Moon phase may also push crappie into slightly shallower feeding positions at first light.

White bass are most likely winding down from the spring spawning run, which peaks on the Colorado River tributaries through April and typically trails off through mid-May. Tributary mouths and shallow channel drops can still yield sporadic action over the next several days, but numbers will thin heading into late May. Plan the bulk of your effort around largemouth and crappie for the highest-percentage weekend outing on all three lakes.

Context

Mid-May is a hinge point on the Highland Lakes. In a typical year, water temperatures across Travis, LBJ, and Buchanan climb through the mid-to-upper 70s °F by the third week of May, pushing largemouth off their beds and into the first wave of sustained post-spawn feeding. Bluegill spawning activity — the shallow-water cue that Tactical Bassin identifies as a key topwater-bass trigger — typically spans mid-May through June at Central Texas latitudes, making this week one of the more historically productive topwater windows of the entire calendar year on these reservoirs.

Striper populations on Buchanan are maintained through TPWD stocking efforts, and Buchanan remains the primary striper destination among the three Highland Lakes. Spring striper action on the chain typically peaks April through May before summer thermocline stratification pushes fish into deeper, harder-to-reach water.

Lone Star Outdoor News reported that 2025 was a record year for Texas anglers, with numerous state fishing records set across Texas waters — a broad indicator of favorable fishery conditions heading into this season. Specific week-over-week comparative data for Travis, LBJ, or Buchanan is not available in this week's intel; My Canyon Lake Fishing noted in early 2025 that TPWD briefly paused its weekly fishing-report format, a gap in structured local intelligence that has made near-term data availability patchier than usual for Central Texas lakes. With the Colorado River running 728 cfs at USGS gauge 08158000 — moderate inflow, not a drought-stress low or a disruptive flood event — there is no hydrologic signal that would push the Hill Country season meaningfully off its historical mid-May cadence.
