Post-spawn bass and crappie fire up on the Highland Lakes as bluegill beds peak
The Colorado River system checked in at 280 cfs at USGS gauge 08158000 on the morning of May 17 — a moderate late-spring flow for the Highland Lakes chain — though no surface temperature reading was available from local instruments. The dominant story across Texas right now is the bluegill spawn: Tactical Bassin reports bass locked into heavy cover and aggressively taking topwater frogs and poppers during peak bluegill bed activity, a pattern that translates directly to the shallow coves and rocky points of Lakes Travis, LBJ, and Buchanan. On the crappie front, LakeForkGuy is calling the current post-spawn window "the most aggressive crappie bite of the year," with fish relocating from spawning flats back to adjacent structure. Texas Fish & Game Magazine highlights electronics-driven targeting as the key to locating blue catfish over deep channel structure this season. Tonight's New Moon means minimal moonlight and compressed low-light feeding windows — first and last hour of daylight will be the prime time to be on the water.

What's Biting
Largemouth Bass
topwater frogs and poppers over shallow bluegill beds at first light
Crappie
tube jigs on post-spawn channel-bend structure at 8–14 feet
Blue Catfish
electronics to locate deep channel schools, then cut bait on the bottom
Striped Bass
mid-lake trolling with live shad in 20–30 feet
What's Next
The New Moon phase eliminates ambient moonlight for the next several nights, historically pressing bass onto shallower feeding flats and tightening the best topwater action into the first and last hour of daylight. Prioritize frogs and poppers over shallow coves with active bluegill beds — Tactical Bassin calls out that exact two-bait rotation during the bluegill spawn peak, with frogs working in heavy matted cover and poppers fishing better along more open water edges. When the sun climbs and the surface bite shuts down, transition to soft plastics and Texas-rigged creature baits worked along the first depth break off those same coves, where post-spawn bass stage to intercept bluegill moving off the beds.
Crappie should remain aggressive through the coming week. LakeForkGuy is flagging what they describe as the most aggressive post-spawn crappie bite of the season, with fish that have relocated from spawning shallows back to adjacent structure. On Lakes LBJ and Buchanan, brushy creek-channel bends and standing timber in the 8–14 foot range are the traditional post-spawn crappie highways — small tube jigs and a slip float are the proven producers at this transition stage.
For catfish, Texas Fish & Game Magazine makes the case for running sonar over deeper channel structure to pinpoint suspended blue catfish schools before anchoring, then presenting cut bait or large live shad on the bottom. This electronics-forward approach tends to pay off increasingly through May and June on Texas impoundments as water temperatures begin to stratify and catfish concentrate near the thermocline.
Striped bass — stocked in Lake Travis by TPWD — tend to push into open mid-lake water during late spring as forage concentrates. No striper-specific report for Travis is available in this data cycle, but the combination of post-spawn shad abundance and warming surface temperatures makes mid-lake trolling with live shad or umbrella rigs in the 20–30 foot range worth investigating once shallow-water action slows.
Lone Star Outdoor News — Fishing reports a record-setting year for Texas anglers broadly, a positive signal for lake productivity heading into Memorial Day weekend. Expect boat pressure on Lake Travis to spike sharply starting May 23 — plan early-morning launches to stay ahead of recreational traffic on the most accessible shoreline structure.
Context
Mid-May on the Highland Lakes sits at a classic inflection point: largemouth bass have typically completed their spawn and are entering the post-spawn recovery and aggressive feeding phase that dominates the next four to six weeks. The bluegill spawn — confirmed by Tactical Bassin as currently in full swing across Texas — historically trails the bass spawn by two to four weeks and serves as the first major post-spawn feeding trigger for large largemouth. If conditions are running on the typical seasonal curve, shallow arms of LBJ and Buchanan are likely approaching the 72–76°F range, with bass concentrating on flat transitions adjacent to active bluegill beds rather than on the primary spawning flats they occupied through April.
No direct water temperature reading was available from USGS gauge 08158000 in this reporting cycle, which limits precision on exactly where fish sit in that transition. It is also worth noting that TPWD briefly suspended its weekly fishing report series earlier this year, per My Canyon Lake Fishing, and the absence of state-agency intel in this cycle reflects that gap in the regional data pipeline. When TPWD regional reports resume, they will be the most reliable source for targeting guidance on Travis and the upper chain.
The current flow reading of 280 cfs at gauge 08158000 falls within a moderate seasonal range and does not suggest the kind of significant inflow event or rapid drawdown that can scatter fish off predictable structure. Stable lake conditions, even without a surface temperature confirmation, generally favor consistent pattern fishing over the reactive scramble that follows major weather swings or dramatic lake-level changes. No unusual seasonal signals — abnormal cool front, flood pulse, or severe drawdown — are evident in the available data for this report period.
