Lake Buchanan is a 23,000-acre reservoir built for power generation, not recreation—but it holds striped bass, largemouth bass, and catfish worth the trip

Lake Buchanan sits at the top of the Highland Lakes chain, about 40 miles northwest of Austin near Burnet. The lake is long and narrow, shaped by the Colorado River that feeds it, and the water level swings hard with power demand and drought. That volatility makes it different from the lakes below it: the shoreline changes, the structure shifts, and the fish move in response. If you know how to read those changes, Buchanan rewards you. If you don't, you'll spend a day casting at empty water.

The striped bass fishery is what draws most people here. Stripers were stocked decades ago and now reproduce naturally in the Colorado River arm. They school in deep water during the day and move shallow to feed at dawn and dusk. Largemouths live throughout the lake in the usual places—brush, rock, timber—and run smaller than you'll find in clearer Hill Country lakes, but they're plentiful. Catfish are everywhere and bite all day, which makes them a solid backup plan when the bass aren't cooperating.

Key Takeaways

  • Striped bass are the main draw; they school deep during midday and move to shallow structure at sunrise and sunset.
  • Water level changes frequently due to power generation, so check the current level before you launch and adjust your fishing depth accordingly.
  • The Colorado River arm holds the most stripers; the main lake body holds largemouths and catfish throughout.
  • Launch ramps are at Burnet Park, Inks Dam, and Tow, each with different amenities and access to different parts of the lake.
  • Summer heat and afternoon wind make early morning and late evening the most productive times to fish.

Where the Fish Live and How Water Level Changes Affect Them

Lake Buchanan's depth varies dramatically. The Colorado River arm—the northern section that feeds the lake—runs 60 to 80 feet deep in places and holds the densest population of stripers. The main lake body is shallower and more open, with depths ranging from 20 to 40 feet. Largemouths scatter throughout both sections, but they concentrate around the few rock outcrops, submerged timber, and creek channels that break up the otherwise featureless bottom.

Water level is the single most important variable. The lake can drop 10 to 15 feet in a few weeks during summer when power demand is high, or rise just as fast when heavy rain hits upstream. When the lake drops, fish move deeper and tighter to structure. Shallow flats that held bass in spring become barren. When it rises, fish spread out and move into flooded brush and timber. Before you fish, check the current level at the Lower Colorado River Authority (LCRA) website or call their water information line. That one piece of information will save you hours of unproductive casting.

Stripers follow a predictable daily pattern. During the day, they hold in the deepest water they can find—often 40 to 60 feet down in the river arm. They're not feeding; they're resting in cool water. At sunrise and sunset, they move shallow to hunt shad and herring. That's when you fish for them. Largemouths don't follow the same pattern; they stay shallow and active throughout the day, but they're more selective about structure. A pile of rocks or a submerged tree matters more than depth.

Striped Bass Tactics and Timing

Stripers at Buchanan respond to live bait and to vertical jigging. Live shad or herring, suspended under a float or on a three-way rig, works well when you're fishing the deep river arm. Drop your bait to 40 to 50 feet and let it sit. Stripers will find it, especially in the hour after sunrise and the hour before sunset. If you're jigging, use a white or chartreuse shad-pattern jig in the 1/2-ounce to 1-ounce range. Work it vertically over deep structure, or cast it toward shallow points and retrieve it with a steady lift-and-drop rhythm.

The Colorado River arm is your best bet for stripers. Launch at Burnet Park or Tow and head north into the river section. The water is clearer there, the structure is more defined, and the fish are more concentrated. The main lake body holds stripers too, but they're more scattered and harder to locate. If you're new to the lake, start in the river arm and learn the deep holes and channel breaks. Once you know where the fish live, you can predict where they'll be at different times of day.

Summer heat changes the game. By July and August, stripers go deep and stay there most of the day. Your window for shallow-water fishing shrinks to the first hour after sunrise and the last hour before sunset. Afternoon fishing is possible if you're willing to fish deep structure with live bait, but most anglers call it a day by mid-morning and return in late afternoon. Winter is the opposite: stripers stay shallower and bite throughout the day, but the water is cold and the fish are less aggressive.

Largemouth Bass and Catfish

Largemouths at Buchanan are a different hunt than stripers. They don't school as tightly, and they don't move as predictably. What they do is hold tight to cover. Rock piles, submerged timber, and the few brush patches that survive the water-level swings hold bass all year. Fish these spots with soft plastics—Texas-rigged worms, creature baits, or small swimbaits—and work them slowly. The bass here aren't aggressive; they're opportunistic. A bait that sits still or moves slowly will draw more strikes than one that zips past.

The main lake body is better for largemouths than the river arm. Launch at Inks Dam or Tow and work the rocky shoreline and the few creek channels that cut into the lake. Early morning and late evening are productive, but unlike stripers, largemouths will bite throughout the day if you're fishing the right structure. Water clarity is moderate—you can see 4 to 6 feet down—so natural colors work better than bright ones.

Catfish are the easiest fish in the lake and the most forgiving. They bite on cut shad, chicken liver, or stink bait, and they bite all day and all night. Fish the deeper holes in the river arm or the main lake body, use a simple three-way rig with a sinker and a short leader, and wait. Catfish at Buchanan run 5 to 20 pounds, and they're strong fighters. If the bass aren't cooperating, catfish will keep you busy and fed.

Launch Ramps, Facilities, and Where to Start

Burnet Park is the main public launch on the north end of the lake, near the town of Burnet. It has a concrete ramp, parking for trailers, and basic facilities. From here, you have direct access to the Colorado River arm, which is the best water for stripers. The ramp can get crowded on weekends, and the parking lot fills early.

Inks Dam is on the south end of the lake, near the town of Burnet as well, and offers access to the main lake body. It has a concrete ramp and parking, and it's less crowded than Burnet Park. If you're targeting largemouths or want to explore the main lake, start here.

Tow is a smaller launch on the east side of the lake. It has a concrete ramp and limited parking. It's a good option if the other ramps are full, and it gives you access to both the river arm and the main lake body. All three ramps charge a small day-use fee. Check current conditions and any closures with the LCRA before you go.

Seasonal Patterns and What to Expect

Spring (March to May) is when stripers move shallow to spawn. They're aggressive and bite readily. Largemouths are also active, and the water level is usually stable. This is the best time to learn the lake if you're new to it.

Summer (June to August) is hot and the water level drops. Stripers go deep and bite only at dawn and dusk. Largemouths slow down. Catfish remain active all day. If you can handle the heat, fish early and late.

Fall (September to November) brings cooler water and more stable conditions. Stripers move shallower again, and largemouths become more active. The lake can be beautiful in October and November, and the fishing is often excellent.

Winter (December to February) is mild by northern standards, but the water is cold. Stripers stay shallower than in summer and bite throughout the day. Largemouths slow down. This is a good time for patient anglers who don't mind the cold.

Gear and Tackle for Buchanan

For stripers, bring a medium-heavy spinning rod or baitcasting rod in the 6.5- to 7-foot range. Pair it with 12- to 20-pound braided line for better sensitivity when jigging deep. A conventional reel works well for live-bait fishing. Bring shad-pattern jigs in white and chartreuse, 1/2-ounce to 1-ounce. Bring a cooler with live shad or herring if you plan to fish live bait.

For largemouths, a medium-power spinning rod or baitcaster in the 6.5-foot range works well. Use 10- to 15-pound monofilament or braided line. Bring a selection of soft plastics: Texas-rigged worms in natural colors (green pumpkin, watermelon), creature baits, and small swimbaits. A few crankbaits in shad patterns are useful for covering water quickly.

For catfish, any medium-power rod will work. Use 15- to 20-pound monofilament. Bring a three-way rig setup, sinkers, and cut shad or stink bait. A headlamp is useful if you plan to fish at night.

Frequently Asked Questions

What's the best time of day to fish Lake Buchanan?

For stripers, sunrise and sunset are most productive. For largemouths, early morning and late evening are best, but they bite throughout the day if you're on good structure. Catfish bite all day and all night. Summer heat makes midday fishing unproductive for stripers and largemouths, so most anglers fish early and return in late afternoon.

Do I need a boat to fish Lake Buchanan?

A boat is helpful because the lake is large and fish are often in deep water, but you can fish from the shore at the launch areas and along the rocky banks. Shore fishing for catfish and largemouths is possible, but you'll have limited access to the stripers that hold in deep water.

What's the water level usually like, and does it affect fishing?

Water level changes frequently due to power generation and rainfall. It can drop 10 to 15 feet in a few weeks or rise just as fast. Lower water concentrates fish in deeper holes; higher water spreads them out into flooded brush. Check the LCRA website before you go to know what to expect.

Are there any restrictions on what I can keep?

Texas Parks and Wildlife sets the rules. Striped bass have a daily limit and a minimum size; largemouths have a daily limit and a minimum size; catfish have a daily limit. Check the current regulations on the TPWD website before you fish, as rules change.

Is Lake Buchanan good for beginners?

Catfish make it beginner-friendly because they're easy to catch and forgiving. Largemouths are moderate in difficulty. Stripers require more knowledge of depth, structure, and timing, so they're better for anglers with some experience. Start with catfish or largemouths to learn the lake, then move to stripers once you understand how the water and structure work.
