The Guadalupe River runs clear and cold from the Hill Country down through the coastal plains, holding largemouth bass, smallmouth bass, catfish, and sunfish across its 250-mile length

The Guadalupe is one of Texas's most accessible rivers for fishing, with public access points scattered throughout its course and a reputation for reliable catches year-round. The upper river near New Braunfels and Gruene flows fast and cold from Canyon Lake Dam, making it ideal for smallmouth bass and trout in cooler months. The middle section slows and warms as it moves southeast, favoring largemouth bass and catfish. The lower river near Gonzales and Cuero becomes wider and slower, holding larger catfish and occasional stripers.

What makes the Guadalupe distinct is the mix of access types: you can wade or float sections that are public, fish from parks and boat ramps, or hire a guide for specific stretches. The river is open year-round, but conditions and fish behavior change with the seasons and water releases from Canyon Lake.

Key Takeaways

  • The upper Guadalupe near New Braunfels holds smallmouth bass and trout in cold water below the dam; the middle and lower river hold largemouth bass and catfish in warmer, slower water.
  • Public access includes boat ramps at Gruene Park, Dunbar Park, and Gonzales Park, plus wading access at several county parks and low-water crossings.
  • Water releases from Canyon Lake Dam control flow and temperature; check the LCRA website before you go, because high water closes some access points and changes fish location.
  • Texas Parks and Wildlife regulations require a valid fishing license; no special stamps are needed for the Guadalupe itself, but check current creel limits for each species.
  • Spring and fall offer the most consistent fishing; summer heat pushes fish deeper and slower, while winter cold concentrates smallmouth in the upper river.

Upper Guadalupe: Cold Water and Smallmouth Bass

The 15 miles immediately below Canyon Lake Dam produce some of the coldest, clearest water on the river. This section holds smallmouth bass, rainbow trout, and brown trout stocked by Texas Parks and Wildlife. The water temperature stays in the 50s and 60s most of the year because it comes from the bottom of the lake, making this stretch productive even in summer when the rest of the river slows.

Smallmouth bass here respond to live shiners, small crankbaits, and soft plastics worked along rocky banks and drop-offs. Trout fishing is best from November through March; use small spinners, spoons, or live minnows. The current is strong enough that wading requires caution, and floating the section requires experience with current and obstacles.

Access points include Gruene Park near New Braunfels, which has a boat ramp and parking, and several low-water crossings upstream. The Guadalupe River State Park sits just downstream of this section and offers wading access and camping. Check water release schedules on the Lower Colorado River Authority (LCRA) website before you go; high releases make wading dangerous and change where fish hold.

Middle Guadalupe: Largemouth Bass and Catfish

From Dunbar Park south to Gonzales, the river widens and slows, water temperature rises, and largemouth bass become the primary target. This 40-mile stretch also holds channel catfish, flathead catfish, and sunfish. The bottom transitions from rock to sand and mud, and vegetation along the banks provides cover for bass.

Largemouth bass respond to topwater lures early and late in the day, and to soft plastics and crankbaits around submerged logs and vegetation. Catfish bite throughout the day on cut bait, chicken liver, or stink bait fished on the bottom. This section is popular with float trips; several outfitters in New Braunfels and Gruene rent canoes and tubes for day trips, though fishing from a tube is limited.

Dunbar Park near Sattler has a boat ramp and parking. Gonzales Park near Gonzales also has a ramp and is a common takeout point for float trips. Several county parks and private landowner access points exist along this stretch; ask locally or check with the Guadalupe River Alliance for current access information.

Lower Guadalupe: Large Catfish and Stripers

South of Gonzales, the river becomes wider, deeper, and slower, with tidal influence beginning near Cuero. This section holds large channel catfish, flathead catfish, and occasional striped bass. The water is warmer and more turbid than upstream, and the current is minimal except during high water.

Catfish fishing dominates here; use large cut bait, live bluegill, or prepared stink baits fished on the bottom at night or early morning. Stripers appear sporadically, especially in spring and fall; fish live shiners or small shad near deeper holes and current breaks. Sunfish and small largemouth are also present.

Gonzales Park serves as access for this section. Cuero Park near Cuero offers another ramp, though the river becomes increasingly influenced by tidal conditions and coastal habitat as you approach the coast. This lower section is less crowded than the upper river and offers a different experience for anglers targeting large catfish.

Seasons and Water Conditions

Spring (March through May) brings warming water, rising flows from spring rains, and active feeding across all species. Largemouth and smallmouth bass are most aggressive, and catfish bite consistently. Water levels can be high, which closes some access points but concentrates fish in deeper holes.

Summer (June through August) heats the water, especially in the middle and lower river. Fish move deeper and slower, and daytime fishing becomes difficult. Early morning and evening are best. Upper river sections near the dam remain cooler and more productive. Floating becomes popular for recreation, which increases pressure on fish.

Fall (September through November) cools the water and triggers aggressive feeding again. Smallmouth bass in the upper river become very active. Largemouth and catfish throughout the river bite well. Water levels typically drop, making wading easier and access more reliable.

Winter (December through February) brings cold water, especially in the upper river. Smallmouth and trout concentrate in deeper holes and move less. Largemouth and catfish in the middle and lower river slow down but still bite on the bottom. Floating is less popular, so fishing pressure drops.

Canyon Lake Dam releases water according to a schedule managed by the LCRA. High releases raise water levels, increase current, and can close wading access. Low releases expose more bank and make wading easier but concentrate fish. Check the LCRA website or call their water release hotline before planning a trip.

Regulations and Licensing

All anglers 17 and older must have a valid Texas fishing license. You can purchase a license online through the Texas Parks and Wildlife Department website, at sporting goods stores, or at many bait shops. Licenses are available as one-day, annual, or multi-year options.

Creel limits and size restrictions vary by species and change periodically. Largemouth bass typically have a 5-fish daily limit with a 14-inch minimum size. Smallmouth bass have a 5-fish limit with a 12-inch minimum. Catfish have no size restriction and a 25-fish daily limit. Sunfish have a 25-fish limit. Check the current Texas Parks and Wildlife regulations before you fish, as these limits are subject to change.

No special permits or stamps are required to fish the Guadalupe River itself. Public access areas may have parking fees or day-use fees; Guadalupe River State Park charges a day-use fee and offers camping. Private landowner access sometimes requires permission or a small fee.

Access Points and Facilities

The Guadalupe has established public access at several parks and crossings along its length. Gruene Park near New Braunfels sits in the upper section and offers a boat ramp, parking, and picnic facilities for anglers targeting smallmouth and trout. Guadalupe River State Park, located near Spring Branch just downstream, provides wading access, camping, and parking for those wanting to stay overnight or explore the upper river on foot.

In the middle section, Dunbar Park near Sattler and Gonzales Park near Gonzales both have boat ramps, parking, and picnic areas. These are the primary launch points for float trips and serve as takeout locations for canoe and tube rentals. Cuero Park near Cuero provides access to the lower river for anglers targeting large catfish and stripers. Several low-water crossings along the river provide free wading access, though parking is often limited; ask at local bait shops or check with the Guadalupe River Alliance for current access information and any changes to public areas.

Frequently Asked Questions

What is the best time of year to fish the Guadalupe?

Spring and fall offer the most consistent fishing across all species. Water temperatures are moderate, fish are actively feeding, and water levels are usually stable. Summer can be productive in the upper river near the dam, where water stays cool. Winter is best for smallmouth and trout in the upper section.

Can I float the Guadalupe in a canoe or tube?

Yes, floating is popular, especially in the middle section between Dunbar Park and Gonzales Park. Several outfitters in New Braunfels and Gruene rent canoes, kayaks, and tubes. Fishing from a tube is limited, but you can float and fish from a canoe or kayak. Always wear a life jacket and check water conditions before you go.

Do I need a guide to fish the Guadalupe?

No, the river is open to public fishing at designated access points. Guides are available if you want local knowledge or help targeting specific species, but they are not required. Local bait shops can provide current conditions and recommendations.

What should I do if water is being released from Canyon Lake Dam?

High water releases raise the river level, increase current, and can make wading dangerous. Some access points close during high water. Check the LCRA website or call their water release hotline before you go. If you are already on the river when a release begins, move to higher ground immediately.

Are there fish in the Guadalupe year-round?

Yes, but the species and location change with the season. The upper river holds trout and smallmouth year-round. The middle and lower river hold largemouth and catfish year-round. Summer heat and winter cold affect feeding activity, but fish are present and can be caught in every season.
