What you'll find at McKinney Falls

McKinney Falls State Park sits about 13 miles southeast of downtown Austin and holds two separate fishing zones: the upper falls area on Onion Creek and the lower falls area downstream. The upper falls is a natural limestone cascade where the creek pools before dropping, and that pool holds smallmouth bass, catfish, and sunfish year-round. The lower falls area, accessible by a separate parking area, offers deeper pools and slower current that attract larger catfish and occasional largemouth bass pushed upstream from the Colorado River system.

The creek runs clear most of the year, which means you'll see what you're casting to — a real advantage when the water level is stable. Spring and early summer bring the highest flows, when the falls themselves run strong and the pools deepen. By late summer and fall, the creek drops to a more manageable level, and the pools concentrate fish in smaller areas, making them easier to locate.

Key Takeaways

  • McKinney Falls has two distinct fishing areas — the upper falls pool and the lower falls area — each requiring separate parking and offering different species and conditions.
  • Smallmouth bass, catfish, and sunfish are the primary species; the upper pool is shallower and clearer, while the lower area holds deeper water and larger catfish.
  • Spring and early summer bring high water and strong current; fall and winter offer lower, clearer pools where fish concentrate in predictable spots.
  • The park charges a day-use fee and requires a Texas Parks and Wildlife Department fishing license; no special permit beyond the standard license is needed.

Tackle and technique for each pool

The upper falls pool responds well to small topwater lures and soft plastics in the 3- to 4-inch range for smallmouth bass. Cast near the base of the falls where current breaks, and work the edges of the pool where the water slows. Catfish in this pool run smaller than downstream — typically 1 to 3 pounds — and will take chicken liver, cut shad, or prepared stink bait fished on the bottom with a simple slip sinker rig.

The lower falls area demands heavier tackle. Catfish here run 5 to 15 pounds regularly, and you'll want 20- to 30-pound braided line on a medium-heavy rod. Fish the deeper holes with 3- to 4-ounce sinkers to keep bait on bottom in the current. Largemouth bass in the lower pool prefer larger swimbaits and crankbaits that mimic the shad and bluegill that move through the creek. Early morning and late evening are most productive; midday heat pushes fish into the deepest holes.

When to fish and water conditions

Spring (March through May) brings the most water volume and the strongest current. The falls run hard, and fish feed aggressively in the turbulent water. This is excellent for smallmouth bass but can make catfishing difficult because bait drifts too quickly. If you fish the spring, use heavier sinkers and shorter casts to keep bait in the strike zone.

Summer (June through August) sees lower flows and clearer water. The upper pool becomes very shallow and clear, which makes fish spooky but also makes sight-fishing possible. Fish early and late; midday sun drives fish deep. Fall (September through November) offers the most stable conditions — moderate water level, clear visibility, and active feeding as fish prepare for winter. Winter (December through February) slows the bite, but catfish remain active, and the lack of crowds makes it a good time to learn the creek's structure.

Access, parking, and park rules

McKinney Falls State Park has two separate parking areas. The main parking lot near the visitor center provides access to hiking trails and the upper falls area; a second lot serves the lower falls and additional trails. Day-use entry costs a small fee per vehicle (the exact amount varies by season). The park is open from sunrise to sunset for day-use fishing.

You must have a valid Texas Parks and Wildlife Department fishing license. You can purchase a license online through the TPWD website, at most sporting goods stores in Austin, or at the park office. No special permit beyond the standard license is required. The park prohibits alcohol, and swimming is not permitted in the creek itself, though wading for fishing is allowed. Catch-and-release is encouraged, but you may keep fish within state limits.

Getting there and what to bring

From downtown Austin, take US-183 south toward Bastrop, then turn east on McKinney Falls Parkway. Follow signs to the park entrance. The drive takes about 20 to 25 minutes depending on traffic. Parking is available at both the main lot and the lower falls lot; arrive early on weekends, as spaces fill by mid-morning.

Bring plenty of water — the creek is not a reliable drinking source, and the park has limited shade. Wear sturdy shoes with good grip; the limestone rocks around the falls are slick, especially after rain. Sunscreen and a hat are essential, and insect repellent helps during summer and early fall. If you're fishing the lower falls area, bring a headlamp or flashlight for early-morning or evening sessions, as the trail can be dark.

Nearby water and alternative options

If McKinney Falls is crowded or conditions aren't right, the Colorado River runs through Austin and holds largemouth bass, catfish, and stripers. Lady Bird Lake (also called Town Lake) in central Austin offers easier access and year-round fishing for largemouth bass and catfish, though it's more urban and less scenic. Barton Springs Pool, also in Austin, is a natural spring-fed pool that stays around 68 degrees year-round, but it's primarily a swimming destination and fishing is not permitted.

For a longer drive, Lake Travis and Lake Austin both sit within 30 minutes of downtown and offer larger reservoirs with more species variety and deeper water. If you want creek fishing similar to McKinney Falls but with fewer crowds, Walnut Creek in north Austin and Bear Creek in southwest Austin both hold smallmouth bass and catfish, though neither has the scenic falls or developed park infrastructure.

Seasonal patterns and what to expect

Spring is the busiest season at McKinney Falls, with families hiking and fishing. The creek runs high and fast, and the falls themselves are dramatic. If you want solitude, fish early morning before the park fills up. Summer brings heat and lower water; the upper pool becomes almost stagnant in late July and August, which can stress fish. Fall is the sweet spot — moderate conditions, active fish, and fewer visitors than spring.

Winter is quiet and cold, but catfish bite consistently. The lower falls area remains fishable year-round because it holds deeper water. The upper falls pool can become too shallow to fish in late summer if drought conditions persist, so check park conditions before making the drive during extended dry spells.

Frequently Asked Questions

Do I need a license to fish at McKinney Falls?

Yes, you must have a valid Texas Parks and Wildlife Department fishing license. You can purchase one online through the TPWD website, at sporting goods stores in Austin, or at the park office. A license is required even for catch-and-release fishing.

What's the difference between the upper and lower falls areas?

The upper falls pool is shallower, clearer, and holds smaller smallmouth bass and sunfish. The lower falls area has deeper water, stronger current, and larger catfish. They require separate parking and offer different fishing experiences.

Can I fish at night?

The park is open sunrise to sunset for day-use fishing, so night fishing is not permitted. Early morning and late evening within park hours are your best times for active feeding.

What's the best time of year to fish McKinney Falls?

Fall (September through November) offers the most stable water levels, clear visibility, and active fish. Spring brings high water and aggressive feeding but also crowds. Summer is slow and hot; winter is quiet but catfish remain active.

Are there fish in the creek during drought?

During extended dry periods, the upper falls pool can become too shallow to fish effectively. The lower falls area holds deeper water and remains fishable. Check park conditions or call ahead if you're visiting during a dry spell.
