What Thorp Spring Park Offers
Thorp Spring Park sits on the western edge of Lake Granbury, about 15 minutes from downtown Granbury, and gives you access to a quieter stretch of water than the main marina areas. The park has a boat ramp, picnic grounds, and a small sandy beach, making it a straightforward launch point for bass and catfish. The lake here runs shallower and warmer than the deeper channels near the dam, which changes what you'll catch and when.
The park itself is county-managed and free to enter. There's no entrance fee, and parking is available near the ramp. The facilities are basic but functional — you'll find restrooms, a few picnic tables, and shade structures. It's not a resort setting, but it's reliable and less crowded than some of the commercial spots around the lake.
Key Takeaways
- Thorp Spring Park has a public boat ramp and beach access on the western side of Lake Granbury, about 15 minutes from town.
- The water here is shallower and warmer than the main lake basin, which means different fish species and seasonal patterns than deeper areas.
- Spring and fall are the most productive seasons for bass; summer catfishing works well from the bank or boat in early morning and evening.
- The park is free to enter and has basic facilities including restrooms, picnic areas, and parking near the ramp.
- Bring your own tackle and bait — there is no tackle shop at the park, and the nearest one is in town.
Bass Fishing in the Shallows
The western shallows around Thorp Spring hold largemouth bass year-round, but spring (March through May) and fall (September through November) are when they feed most predictably. In spring, bass move into the shallows to spawn, and you'll find them in 3 to 8 feet of water around any structure — fallen trees, rock piles, or the old creek channel that runs through this part of the lake.
Throw crankbaits, soft plastics, and topwater early in the morning or in the last hour before dark. The water clarity here is usually moderate, so you don't need to go too deep or use subtle colors. Chartreuse and white work well. In summer, the shallows heat up and the bass move to deeper water or to the shade of docks and overhanging trees. If you fish summer, focus on early morning, and work the edges where shallow water meets the drop-off.
Fall is often the best season because the water cools and bass feed aggressively throughout the day. You'll catch fish on the same shallow structure you fished in spring, and the weather is more comfortable for a full day on the water.
Catfish and Bank Fishing
If you don't have a boat, Thorp Spring Park is one of the better bank-fishing spots on Lake Granbury. The beach area and the bank near the ramp give you room to cast, and catfish — both channel cats and blues — patrol the shallows, especially at night. Bring cut bait (shad or bluegill), chicken liver, or stink bait, and fish the bottom with a simple three-way rig or a slip sinker.
Catfish bite best from late spring through early fall, and night fishing is more productive than day fishing. Set up an hour before dark, and plan to stay until midnight or later. The park has lights near the parking area, so you won't be completely in the dark, but bring a headlamp and a cooler. Catfish can run large here — 20 to 40 pounds is not unusual — so use sturdy rod and reel, not light tackle.
In winter, catfish slow down but don't stop. You can still catch them during the day if you fish deep and move slowly. The shallows freeze out, so focus on any deeper holes or channels you can reach from the bank.
Seasonal Patterns and Water Conditions
Lake Granbury is a warm-water reservoir, and Thorp Spring Park sits in the shallowest, warmest part of it. Water temperature swings from the low 40s in January to the high 80s in July and August. This affects not just what bites, but where fish are and how active they are.
Spring (March–May): Water warms from 50 to 70 degrees. Bass spawn, and shad move into the shallows. This is prime time for both species. Crappie also bite well in early spring if you have a small boat or can fish from the bank near structure.
Summer (June–August): Water reaches 80+ degrees. Bass and most panfish move deep or to shade. Catfish and some stripers become the main target. Early morning and evening are essential.
Fall (September–November): Water cools from 75 to 55 degrees. Bass return to the shallows and feed hard. This is the second-best season after spring.
Winter (December–February): Water drops to 40–50 degrees. Fish are sluggish and deep. Catfish and some bass can still be caught, but success requires patience and slow presentations.
What to Bring and How to Get There
Thorp Spring Park is located on Park Road 17, off Highway 67 on the west side of Granbury. From downtown, take Highway 67 west about 10 miles, then turn north on Park Road 17 and follow signs to the park. It's about a 15-minute drive from the town square. Parking is free and usually available, even on weekends.
Bring your own tackle, rods, and bait. There is no tackle shop at the park. The nearest shops are in Granbury itself — about 15 minutes away — so plan ahead. If you're launching a boat, the ramp is concrete and well-maintained, but it can get crowded on weekends during spring and fall. Arrive early if you want a smooth launch.
The park has restrooms and picnic tables, but no food service. Bring water, snacks, and sunscreen. If you're staying late for catfish, bring a headlamp, bug spray, and a cooler for your catch. Cell service is spotty in some areas of the park, so don't rely on your phone for navigation once you're on the water.
Local Regulations and Licensing
Texas Parks and Wildlife Department (TPWD) sets the rules for Lake Granbury. You need a valid Texas fishing license to fish from the bank or boat. Licenses are available online at tpwd.texas.gov, at most sporting goods stores, and at some convenience stores in Granbury. 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 limit. Catfish have no size limit and no daily limit. Crappie and other panfish have a 10-inch minimum and a 25-fish daily limit. Check the current regulations before you fish — TPWD updates rules periodically, and it's your responsibility to know what's in effect.
The park itself has no special restrictions beyond standard lake rules. Alcohol is permitted in designated areas. Camping is not allowed at Thorp Spring Park, but there are RV parks and campgrounds nearby in Granbury if you want to stay overnight.
Frequently Asked Questions
Can I fish at night from the bank?
Yes. The park is open from sunrise to sunset officially, but night fishing for catfish is common and tolerated. Bring a headlamp and stay aware of your surroundings. The parking area has lights, so you won't be completely dark, but plan to leave before the park closes in the morning.
Is there a tackle shop at the park?
No. The nearest tackle shops are in Granbury, about 15 minutes away. Bring all your gear with you, or stop in town before heading to the park. If you forget something, you'll have to make the drive back.
What's the best time of year to fish here?
Spring (March–May) and fall (September–November) are the most productive. Bass bite well, the weather is comfortable, and you don't have to fish in extreme heat or cold. Summer works for catfish and early morning bass, but it's hot. Winter is slow but possible if you're patient.
Do I need a boat to fish Thorp Spring Park?
No. The bank and beach give you good access without a boat. Catfish and some bass can be caught from shore. A boat opens up more water and deeper structure, but it's not required to have a productive day.
What size catfish are in this part of the lake?
Channel catfish typically run 5 to 15 pounds, but 20 to 40 pounders are caught regularly, especially at night. Blue catfish can be larger. Use sturdy tackle and be prepared for a strong fight if you hook a big one.
