What Lake Bastrop Offers

Lake Bastrop is a 918-acre impoundment on the Colorado River in central Texas, about 30 miles southeast of Austin. The lake sits in a transition zone between the Hill Country and the coastal plains, which shapes both the fish you'll find and the way the water behaves through the year. It's a working reservoir — the City of Bastrop draws water from it — so water levels drop noticeably in summer and fall, exposing stumps and creating shallow flats that concentrate fish.

The lake holds largemouth bass, catfish, and sunfish. Largemouths are the main draw, and they run smaller here than in some Texas reservoirs — most fish you'll land fall between 1 and 3 pounds, though 4- to 5-pounders show up regularly. The lake also holds a solid population of channel catfish and flatheads, plus bluegill and other panfish that make for good light-tackle fun if bass aren't cooperating.

Bastrop is a town lake, not a destination lake. That means it's less crowded than major reservoirs to the north and west, but also less developed. There's no full-service marina, no tackle shop on the water, and no resort. You'll need to bring what you need or make the 30-minute drive back to Bastrop or Austin.

Key Takeaways

  • Lake Bastrop holds largemouth bass averaging 1 to 3 pounds, with occasional fish to 5 pounds, plus catfish and panfish in a 918-acre impoundment on the Colorado River.
  • Water levels drop significantly in summer and fall, concentrating fish in deeper holes and creating shallow flats that hold bass in early morning and late afternoon.
  • The lake has two public boat ramps — one at Bastrop State Park and one at the city park — but no marina, fuel dock, or on-water services.
  • Spring (March through May) and fall (September through November) produce the most consistent fishing, while summer requires early starts and deep-water focus.
  • Largemouths respond to topwater lures, soft plastics, and crankbaits in shallow water; catfish take cut bait and live bluegill in deeper holes year-round.

Where to Launch and What to Bring

The main public boat ramp is at Bastrop State Park on the north shore. It's a single-lane concrete ramp in decent condition, and there's a small parking area. The ramp can get crowded on weekends, especially in spring. The city also maintains a smaller ramp at Bastrop City Park on the south side of the lake, which is less trafficked but also less developed — no amenities, just the ramp and a small lot.

Neither ramp has fuel, ice, or tackle. The nearest gas station is in Bastrop proper, about 5 miles from the state park ramp. Bring everything you'll need for the day: water, snacks, sunscreen, and a full tank. If you're planning to fish catfish at night, bring a headlamp and tell someone where you're going — the lake has no night lighting and cell service can be spotty on the water.

A 14- to 17-foot bass boat or center-console works well here. The lake is shallow in many areas — average depth around 15 feet — so a boat with a shallow-water jack plate or a kayak gives you access to flats and coves that deeper-draft boats can't reach. If you're launching a kayak, both ramps work, though the state park ramp is more stable for loading.

Spring and Fall: The Prime Seasons

March through May and September through November are when Lake Bastrop fishes best. Water temperatures sit in the 60s and 70s, bass move shallow to feed, and you can catch fish throughout the day. Spring is the most predictable: bass spawn in the coves on the north and east sides of the lake, and they'll hit topwater lures and soft plastics aggressively as they move to and from deeper water.

In spring, focus on the creek channels and the deeper edges of the flats. Bass use these as highways between shallow spawning areas and deeper holding zones. A 1/4-ounce jig with a crawfish trailer or a 4-inch soft plastic rigged Texas-style will catch fish consistently. Early morning — first light through 9 a.m. — is most productive, but you can catch fish all day if you stay near structure.

Fall fishing mirrors spring in many ways, but the water cools faster and bass move deeper sooner. By November, most fish are in 12 to 20 feet of water, relating to the old creek channel that runs down the middle of the lake. Switch to deeper-diving crankbaits or Carolina-rigged soft plastics, and fish slower. The bite is still there, but you have to work for it more deliberately.

Summer: Early Starts and Deep Water

June through August is the hardest time to fish Lake Bastrop. Water temperatures climb into the 80s and 90s, the lake level drops as the city draws water, and bass move to the deepest holes they can find. The bite is concentrated in early morning — you need to be on the water before sunrise and off by 10 a.m. — and again for an hour or two at dusk.

Target the deeper holes along the old creek channel, particularly where it intersects with the dam. Bass will suspend 15 to 25 feet deep, so a deep-diving crankbait or a drop-shot rig with a small soft plastic works better than topwater. Catfish, by contrast, bite all day in summer. They move to the deepest holes to escape the heat, and they'll take cut shad or live bluegill fished on the bottom with a simple three-way rig.

If you're fishing summer, plan to fish early, take a break during the heat of the day, and return for an evening session. The water is clearer in summer than in spring, so use smaller lures and lighter line — 8- to 10-pound test for bass, 12- to 15-pound for catfish.

Winter: Slow and Deliberate

December through February is slow but fishable. Water temperatures drop into the 40s and 50s, and bass become lethargic. They stack up in the deepest holes and move very little. The bite is short and subtle — you'll feel a light tap rather than an aggressive strike — so use light line and pay close attention.

A 1/4-ounce jig or a small soft plastic fished very slowly on the bottom will catch fish, but you'll work hard for every one. Catfish are more reliable in winter; they don't feed as actively as in summer, but they'll still take bait if you give them time. Fish the deepest holes with cut bait and patience. Winter is a good time to fish if you want solitude and don't mind a slow bite.

Tackle and Techniques That Work

For largemouth bass, bring a 6- to 7-foot medium-power spinning rod with 10- to 12-pound braided line. Topwater lures — poppers and walking baits — work well in spring and early summer in shallow water. Soft plastics rigged Texas-style or on a jighead are your bread and butter year-round. Crankbaits in the 2- to 3-inch range work in spring and fall when bass are active; switch to deeper-diving models in summer and winter.

For catfish, a 6- to 7-foot medium-heavy rod with 15- to 20-pound monofilament is standard. Use a simple three-way rig with a 1- to 2-ounce sinker and a 12-inch leader to a circle hook. Cut shad, live bluegill, or chicken liver all work. Fish the deepest holes you can find, set the rod in a holder, and wait. Catfish bite best at dusk and through the night.

Panfish — bluegill and other sunfish — respond to small jigs, inline spinners, and live crickets or worms. A light spinning rod with 4- to 6-pound line is all you need. Fish the shallow flats and around any visible cover — fallen trees, brush, or dock pilings — in early morning or late afternoon.

Rules, Permits, and What to Know Before You Go

You'll need a Texas fishing license to fish Lake Bastrop. You can buy one online through the Texas Parks and Wildlife Department website, at any Walmart or Academy Sports, or at the Bastrop State Park office. A one-day license costs less than a full-year license if you're just visiting.

Bass have a 14-inch minimum length limit and a five-fish daily bag limit. Catfish have no size limit and a 25-fish daily bag limit. Panfish have no size or bag limit. These rules can change, so check the current regulations on the TPWD website before you fish.

The lake is open to the public, but Bastrop State Park charges a day-use fee (currently around $5 per vehicle). The city park ramp is free. No gas motors are allowed on the lake — only electric trolling motors or paddle power. This keeps the lake quiet and the water relatively clean, but it also means you'll be moving slowly and covering less water than on a lake with gas engines.

Frequently Asked Questions

Can I fish from shore at Lake Bastrop?

Yes. Bastrop State Park allows shore fishing along parts of the north bank, and the city park has some shoreline access. Shore fishing is slower than boat fishing because you can't reach the deeper holes where bass hold in summer, but it's a good option if you don't have a boat or want to fish light and mobile.

What's the best time of day to fish?

Early morning — first light through 9 a.m. — is most productive year-round. The second-best window is the last hour or two before dark. Midday fishing is slow except in spring and fall when water temperatures are moderate. In summer, fish early morning only unless you're targeting catfish, which bite all day.

Do I need a guide to fish Lake Bastrop?

No. The lake is small enough and well-known enough that you can fish it on your own with a map and basic knowledge of bass behavior. If you're new to the area or want to learn the deeper structure quickly, a local guide can save time, but it's not necessary.

Is the water safe to drink or swim in?

The lake is a municipal water supply, so it's treated and monitored. Swimming is not allowed. Drinking the water directly from the lake is not recommended — bring your own drinking water.

What should I do if I hook a large catfish?

Catfish over 20 pounds are common in Lake Bastrop, especially flatheads. Use a net if you have one, and keep your rod tip up to avoid losing the fish. Catfish have sharp spines on their pectoral fins, so handle them carefully or use a lip gripper. If you're keeping the fish, a stringer works, but a cooler with ice is better for quality.
