Bluegill Spawn Fires Up Largemouth on Hill Country Reservoirs
The bluegill spawn is in full swing for Texas bass anglers this week — per Tactical Bassin, that means largemouth are locked on shallow heavy cover and will commit aggressively to topwater frogs and swimbaits. USGS gauge 08158000 logged Colorado River inflow into Lake Travis at 1,740 cfs as of early Sunday morning, a moderate but not flood-stage pulse that may cloud upper-lake creek arms while leaving main-basin visibility intact. Regional reservoir levels are running above last year's benchmarks: My Canyon Lake Fishing reports nearby Canyon Lake sitting eight feet higher than the same date in 2025, with conditions described as "ideal for boating and fishing." Tonight's New Moon sharpens dawn and dusk feeding windows, making the next two to three days some of the better low-light topwater opportunities of early summer. No direct on-water reports for Travis, LBJ, or Buchanan surfaced in this cycle; the conditions picture is built from regional and seasonal context.

What's Next
The New Moon tonight, combined with the ongoing bluegill spawn, creates a compressed but productive bite window for largemouth bass on Travis, LBJ, and Buchanan. Tactical Bassin documents big bass staging in heavy shallow cover during the bluegill spawn — frog patterns walked over submerged brush, timber, and rocky shoreline structure are the top call. Expect the pattern to hold through at least mid-week as bluegill continue bedding in the 1–4 foot range.
Colorado River inflow is running at 1,740 cfs per USGS gauge 08158000 as of early Sunday morning. That is a moderate flow — enough to push some turbidity into the upper lake arms and creek channels on Travis but not enough to blow out main-basin clarity. Anglers running the upper Colorado arms should work the clean side of stain lines; those on LBJ and Buchanan can expect clearer open-water conditions in the main basins.
Striper fishing on Lake Travis historically peaks before thermoclines lock in by late May or early June. No direct striper reports are available this cycle, but moderate inflow and above-average lake levels suggest fish have not yet retreated to strict summer depth structure. Subsurface presentations — white swimbaits and umbrella rigs — worked along the 20–35 foot transition zone near main-lake points and the dam section are worth exploring before that window closes.
Looking ahead to the Memorial Day weekend: late-May central Texas heat will push midday surface activity down sharply. Plan primary windows around dawn (6–8 a.m. CDT) and dusk (7:30–9 p.m. CDT). The New Moon transitioning to a waxing crescent through the week will tend to sharpen those low-light feeding edges further. Texas Fish & Game Magazine has highlighted electronics as the key tool for locating blue and flathead catfish on Texas impoundments — deep brush piles and main-channel bends fished at night with cut shad are productive through late May before summer heat fully sets in.
Check official lake-level pages for current pool elevations on Travis and LBJ before launching, as ramp access can vary with fluctuating levels.
Context
Mid-May on the Highland Lakes chain typically marks the close of the spawning period and the beginning of the summer feeding transition for largemouth bass. By the second week of May in most years, fish on Travis, LBJ, and Buchanan have moved off their beds and are staging on secondary points, channel edges, and mid-depth structure. The bluegill spawn — which peaks in central Texas from late April through early June at water temps in the 68–75°F range — is the defining forage event of this transition, reliably concentrating bass in predictable shallow locations, as Tactical Bassin's current coverage of the pattern confirms across Texas and neighboring states.
Lake-level context is measurably positive this year. My Canyon Lake Fishing reports nearby Canyon Lake running eight feet higher than the same date in 2025, a regional indicator that the Hill Country watershed came through the 2025–2026 wet season in better shape than the prior year. Lake Travis and the Highland Lakes have historically been vulnerable to significant draw-down during drought cycles — conditions that stressed fish populations and boat-ramp access in 2022 and 2023. Above-average storage heading into summer is a welcome reversal for anglers on all three reservoirs.
Lone Star Outdoor News notes this has been a record year for Texas anglers broadly, a signal consistent with improved lake conditions and stronger forage cycles across the state's freshwater systems. No direct comparative benchmarks for Travis, LBJ, or Buchanan are available in this cycle's intel pull to pin down specific catch rates versus prior years, but the regional indicators suggest conditions are on schedule or slightly ahead of a normal spring progression. Striper activity on Travis, which typically plateaus once the thermocline establishes in late May or early June, should still be accessible at this point — on track with historical timing for this week of the season.
