Lake Buchanan is Highland Lakes striper country that I keep meaning to get to. The combination of deep, clear water and a TPWD-rated striper fishery in that Hill Country granite setting is hard to resist.

Lake Buchanan Fishing Report
Updated October 2, 2026Synthesized from current fishing reports · Updated weekly
Lake Buchanan is running warm this week with water surface temperatures ranging from 84-86 degrees, and anglers are finding that fish are seeking cooler pockets and deeper structure to escape the August heat. The current conditions have fish scattered, but guides are reporting that staying mobile and keeping a sharp eye on the water is essential right now. Crappie catches are fair on deep timber and brush piles in the 30-35 foot of water range, though the fish aren't stacked tightly, so anglers need to move between locations to find them.
The bite has been strongest during the first two hours after daylight and again during the last two hours before dark, and this week anglers are finding topwater action to be one of the most productive patterns. Right now, the key to success is staying on the move and covering water while watching for surface activity. Schools of fish aren't holding in one spot for long, so anglers who keep their eyes peeled for breaking fish are putting more fish in the boat. Once the sun climbs high, the action slows considerably, making early morning and late evening the prime windows to fish.
Anglers are finding that downsizing presentations is making a noticeable difference this week, as fish are keyed in on smaller baitfish right now. Oversized topwaters and live bait that's too big are causing anglers to miss out on strikes. For crappie, minnow-tipped jigs have been a little better than jigs alone, though good technique with a jig alone will still draw strikes. The key this week is matching the hatch with smaller lures and baits, being prepared to move often, and capitalizing on those low-light windows when fish are most active.

Lake Buchanan Fishing Strategies by Species
Seasonal patterns and techniques by target species · Verified against official sources
Striped bass are the signature species at Lake Buchanan, with TPWD identifying it as one of the best striper fisheries in Texas: annual stockings since 1977 have built a strong population in the clear, deep Highland Lakes water. Spring is the most accessible season as stripers move into the upper Colorado River arm and surface schooling begins on the main lake points, while fall thermocline breakdown brings another round of surface action. White bass, largemouth bass, Guadalupe bass, and blue catfish round out the fishery, with the deep channel areas near the dam holding the largest blue catfish. TPWD statewide regulation for striped and hybrid bass: 18-inch minimum, 5-fish daily combined.
Lake Buchanan Striped Bass Fishing Report
Lake Buchanan is regarded by TPWD as one of the best striped bass fisheries in Texas. Annual TPWD stockings since 1977 have maintained a robust striper population in the lake's deep, clear Highland Lakes water. TPWD statewide regulation: striped and hybrid striped bass: 18-inch minimum, 5-fish daily combined bag. Verify at tpwd.texas.gov before fishing. Spring is the most accessible striper season on Lake Buchanan. Fish move from the deep main lake basin into the upper Colorado River arm and the tributary areas during warming water temperatures, making them easier to target with live bait and large swimbaits. Surface schooling activity on the main lake points in early morning from April through June produces exciting topwater striper fishing. Summer stripers suspend near the thermocline in 25 to 45 feet in the main lake basin. Downrigger trolling with large swimbaits and live shad produces fish when surface activity shuts down. The deep, cold water near the dam holds the largest stripers through the hottest months. Fall surface schooling returns as the thermocline breaks down: fish push shad to the surface on the main lake points and near the upper river arm in September and October.
Lake Buchanan White Bass Fishing Report
White bass are abundant throughout Lake Buchanan and provide excellent year-round fishing. The spring spawning run into the upper Colorado River arm and the major creeks is one of the most popular fishing events on the lake: from February through April, large schools of white bass concentrate in the current areas and can be caught rapidly on small spinners, jigs, and tiny crankbaits. TPWD statewide: 10-inch minimum, 25-fish daily bag. Summer and fall white bass school with stripers on the main lake, chasing shad in surface blitzes that are highly visible from a distance.
Lake Buchanan Largemouth Bass Fishing Report
Largemouth bass at Lake Buchanan are described by TPWD as "under-rated": the lake's clear, deep Highland Lakes water and rocky shoreline structure produce quality fish that receive less pressure than the striper fishery. Guadalupe bass: Texas's state fish: are also present throughout the rocky structure areas. TPWD statewide: largemouth/smallmouth 14-inch minimum, 5-fish daily combined all black bass; Guadalupe bass no minimum. Verify at tpwd.texas.gov. Spring largemouth fishing is best in the protected coves and the upper river arm where timber and brush provide spawning habitat. The granite rock points and ledges on the main lake produce fish through summer with finesse presentations in 12 to 20 feet. The clear Hill Country water rewards patient, accurate casting over power-fishing approaches.
Lake Buchanan Blue Catfish Fishing Report
Blue catfish dominate the catfish population at Lake Buchanan, per TPWD, with channel and flathead catfish also present. The deep channel bends and the rocky transitions near the dam area hold the largest blue catfish on the lake. Cut shad and skipjack herring fished on the bottom in 20 to 40 feet of water near the main channel structure produce trophy-class blue catfish. Summer night fishing from the bank access areas near the upper Colorado arm also produces consistent channel catfish through warm months. Verify current TPWD catfish regulations at tpwd.texas.gov.
If you haven't replaced your braided line in a season or two, now's the time. Braid holds up better than mono, but abrasion from wood and rock adds up. Reaction Tackle is one of my favorite places to order from.

About Lake Buchanan
Lake Buchanan has been on my Texas radar for a while. The Highland Lakes granite country is stunning, and the idea of targeting striped bass in that setting is genuinely appealing. It's one of those Texas lakes where I'd want to spend a full weekend, not just a day trip.
Lake size and location. Lake Buchanan covers 22,211 acres on the Colorado River in Burnet and Llano counties, west of the city of Burnet in the Texas Hill Country. Buchanan Dam, completed in 1937 by the LCRA (Lower Colorado River Authority), created the largest of the six Highland Lakes that stretch from Austin northwest into the Hill Country. Maximum depth is 132 feet. The lake's granite outcroppings and cedar-juniper terrain are characteristic of the Llano Uplift geology.
TPWD striped bass program. TPWD has stocked striped bass in Lake Buchanan annually since 1977. The program has produced one of the most consistent striper fisheries in Texas: TPWD specifically identifies Buchanan as one of the best striped bass lakes in the state.
Regulations (verify at TPWD). Statewide TPWD regulations apply. Striped/hybrid striped bass: 18-inch minimum, 5/day. Largemouth/smallmouth bass: 14-inch minimum, 5/day combined all black bass. White bass: 10-inch minimum, 25/day. Guadalupe bass: no minimum. Always verify at tpwd.texas.gov before fishing.
Highland Lakes chain. Lake Buchanan is the uppermost and largest of the six LCRA Highland Lakes on the Colorado River. The chain from north to south: Buchanan → Inks Lake → LBJ → Marble Falls → Travis → Austin. Each lake has distinct fishing character: Buchanan's size and depth make it the premier striper and blue catfish fishery in the chain.
