Beltzville Lake is a 949-acre reservoir in Carbon County that holds largemouth bass, smallmouth bass, walleye, and catfish

Beltzville Lake sits in the foothills of the Pocono Mountains near Lehighton, about 90 minutes north of Philadelphia. The lake is managed by the Pennsylvania Department of Conservation and Natural Resources as part of Beltzville State Park. It's a working reservoir—built to supply water to the Lehigh River—but it's open year-round to the public for fishing, boating, and swimming.

The lake holds a solid mix of warm-water species. Largemouth bass are the most common target, with fish running 12 to 16 inches typical and occasional fish over 4 pounds. Smallmouth bass are present but less abundant than largemouths. Walleye fishing can be productive in spring and fall, especially at dawn and dusk. Channel catfish and flathead catfish are there too, and catfish anglers often fish at night or early morning.

Water clarity varies by season. Spring runoff can cloud the water, but by summer it's usually clear enough to sight-fish in the shallows. Fall tends to be the clearest season overall.

Key Takeaways

  • Beltzville Lake requires a valid Pennsylvania fishing license, which you can buy online or at any sporting goods retailer before you arrive.
  • The lake has a public boat launch at the main park area, and you can also fish from shore at several access points around the perimeter.
  • Largemouth bass fishing is best in spring (April through May) and fall (September through October), when fish move into shallow water.
  • Walleye are most active at dawn and dusk in spring and fall; catfish bite throughout the year but are most predictable at night.
  • The lake sits at about 1,200 feet elevation and can be windy in afternoon hours, so plan your trip for early morning or evening.

Seasons and What Fish Are Biting

Spring (April through May) is the prime season for largemouth bass. Fish move out of deep winter holes into shallow bays and along weed lines. Throw topwater lures, soft plastics, and crankbaits in 4 to 8 feet of water. Walleye also bite well in spring, especially in the first hour after sunrise and the last hour before sunset. Live shiners or small crankbaits work best.

Summer (June through August) slows the bite for bass as fish move deeper to cooler water. Early morning and late evening are your best windows. Catfish remain active throughout the day and night. If you're targeting bass in summer, focus on deeper structure—drop-offs, submerged trees, and the channel that runs through the middle of the lake. Walleye fishing drops off as water warms.

Fall (September through October) is the second-best season. Bass return to shallower water as temperatures drop, and the lake becomes clearer. Walleye bite again in morning and evening hours. This is also when flathead catfish are most active; they prefer live baitfish and hunt at night.

Winter (November through March) is slow but not impossible. Some anglers fish for catfish through the ice or from shore. Bass fishing is unpredictable; when it happens, it's usually midday when the sun warms the water slightly. The lake does not freeze solid most years, but ice can form along the edges.

Access, Parking, and Boat Launch

Beltzville State Park has a developed boat launch on the north side of the lake, near the main park entrance. The launch is a concrete ramp with parking for about 40 vehicles and trailers. There is a small day-use fee—currently $7 per vehicle—payable at the park office or at an automated station. The launch is open dawn to dusk year-round.

Shore fishing is also available at several spots. The park has a fishing pier near the boat launch, and you can walk along parts of the shoreline. A second parking area on the south side of the lake (near the dam) offers additional access, though the shoreline there is rockier and less developed.

To reach Beltzville State Park from Lehighton, take PA-476 north and follow signs for the park. The address is 2950 Pohopoco Drive, Palmerton, PA 18071. Cell service is spotty in the park, so download directions before you arrive.

Regulations and Licensing

You must have a valid Pennsylvania fishing license to fish Beltzville Lake. Licenses are sold online through the Pennsylvania Fish and Boat Commission website, at any sporting goods retailer, and at some convenience stores. A one-day license costs less than a full-year license if you're visiting once. You do not need a separate permit for the lake itself—the state license covers all public waters in Pennsylvania.

Bass have a 12-inch minimum size limit and a daily creel limit of 6 fish (combined largemouth and smallmouth). Walleye are 15 inches minimum with a 6-fish daily limit. Catfish have no size limit and no daily creel limit. Check the current Pennsylvania fishing digest before you go, as regulations can change year to year.

If you're bringing a boat, Pennsylvania requires registration for any motorized vessel. Boats under 20 feet with an electric motor only do not need registration, but gas motors do. The boat launch staff will ask to see your registration when you launch.

What Tackle and Bait to Bring

For largemouth bass, pack a medium-power spinning or baitcasting rod with 8- to 12-pound monofilament or braided line. Bring a mix of topwater lures (poppers and walking baits), soft plastics (4- to 6-inch worms and creature baits), and crankbaits in natural colors. Bass at Beltzville respond well to crawdad-pattern baits, especially in spring.

For walleye, a 6- to 7-foot medium-light rod with 6- to 8-pound line works well. Live shiners (4 to 6 inches) are the most reliable bait. If you prefer lures, small crankbaits (2 to 3 inches) in silver or gold are effective, especially at dawn and dusk.

For catfish, bring a sturdy rod rated for 20- to 30-pound line and a conventional reel. Catfish will take chicken liver, cut shad, live bluegill, or prepared stink baits. Set up a rod holder and let the bait sit on the bottom. Flathead catfish prefer live baitfish over dead bait, so if you're targeting them specifically, bring live shiners or bluegill.

You can buy live bait at tackle shops in Lehighton and Palmerton, but it's often cheaper and more convenient to bring your own or catch shiners the day before in a nearby stream.

Nearby Amenities and Lodging

Beltzville State Park has a picnic area, restrooms, and a small concession stand (open seasonally). There is no on-site lodging at the park itself, but the town of Lehighton is 10 minutes away and has motels, restaurants, and a grocery store. Palmerton, closer to the park entrance, is smaller but has a few local options.

If you want to camp, the nearest state park campground is at Hickory Run State Park, about 20 minutes away. Several private campgrounds also operate in the area. Many anglers fish Beltzville as a day trip from the Lehighton area rather than staying overnight.

The lake is also popular for swimming and picnicking in summer, so expect crowds on weekends. Weekday mornings are quieter and better for fishing.

Common Mistakes and How to Avoid Them

The biggest mistake is fishing the middle of the lake in midday. Beltzville is relatively shallow—average depth around 30 feet—and fish move to structure and shade during bright daylight. Focus on early morning and late evening, and fish near weed beds, fallen trees, and the shoreline.

A second common error is ignoring the wind. The lake is exposed and can get rough in afternoon hours, especially in spring and fall. Launch early, fish the windward side in morning (where baitfish concentrate), and plan to be off the water by early afternoon if the forecast calls for wind.

Many anglers also underestimate how much the lake level fluctuates. As a working reservoir, water levels can drop 10 feet or more during dry spells or when the lake is being drawn down for maintenance. If you fished it last year, the shoreline and shallow structure may look different. Ask at the park office about current water levels before you fish.

Frequently Asked Questions

Do I need a boat to fish Beltzville Lake?

No. Shore fishing is productive, especially from the fishing pier near the boat launch and along the north shoreline. A boat gives you access to deeper water and more structure, but many anglers catch fish from shore, particularly in spring and fall when bass move shallow.

What's the best time of day to fish Beltzville?

Early morning (one hour before sunrise to mid-morning) and late evening (two hours before sunset to dark) are most productive. Midday fishing is slow except for catfish, which bite throughout the day and night. Overcast days are better than bright sunny days.

Can I fish in winter?

Yes, but it's slow. Some anglers fish for catfish from shore in winter. The lake rarely freezes solid enough for safe ice fishing. If you do fish in winter, wear a life jacket if you're near the water and tell someone where you're going.

Where can I buy a fishing license?

Online at the Pennsylvania Fish and Boat Commission website, at any sporting goods store (Dick's Sporting Goods, Cabela's, local tackle shops), and at some Walmart and convenience stores. A one-day license is cheaper than a full-year license if you're visiting once.

Is there a fee to fish Beltzville Lake?

There's a $7 day-use fee per vehicle to enter Beltzville State Park. This covers parking and access to the boat launch, pier, and shoreline. The fee is separate from your fishing license.
