PENNSYLVANIA - Pennsylvania is a premier destination for freshwater anglers, boasting everything from the massive Great Lakes to deep mountain reservoirs. As of 2026, the state's fishery management has seen a surge in "trophy-class" catches, particularly in the larger impoundments where diverse habitats support a wide variety of species.If you are looking for the biggest water to cast a line, here are the largest fishing lakes in the Commonwealth, categorized by their scale and geography.
1. Lake Erie: The Great Giant
While only a portion of Lake Erie belongs to Pennsylvania—about 512,000 acres of water and 77 miles of shoreline—it is undisputed as the largest fishing destination in the state.
- Primary Targets: Smallmouth Bass, Walleye, Yellow Perch, and Steelhead.
- Why Fish Here: It is globally recognized as one of the best smallmouth bass fisheries in the world. The "Steelhead Alley" in the tributaries during fall and winter is a bucket-list experience for fly-fishers.
2. Pymatuning Reservoir: The Inland King
Spanning approximately 17,088 acres, Pymatuning is the largest inland lake in the Commonwealth, though it is shared with Ohio.
- Primary Targets: Walleye, Muskellunge, Crappie, and Channel Catfish.
- Pro Tip: It is known for its high Walleye density. Because the lake is relatively shallow, averaging 15 feet, it warms up quickly in the spring, making for an excellent early-season bite.
3. Allegheny Reservoir (Kinzua Dam)
Tucked into the Allegheny National Forest, this reservoir covers about 12,000 acres at normal pool and extends across the border into New York.
- Primary Targets: Northern Pike, Walleye, Smallmouth Bass, and Muskellunge.
- The Draw: Its rugged, forested shoreline offers a wilderness fishing experience unlike the more developed suburban lakes. It is a top choice for those seeking "big water" Pike.
4. Raystown Lake: The Largest Entirely in PA
If you are looking for the biggest lake that doesn't cross a state line, Raystown Lake in Huntingdon County is the crown jewel. It covers roughly 8,300 acres and reaches depths of 200 feet.
- Primary Targets: Striped Bass, Lake Trout, Atlantic Salmon, and Largemouth Bass.
- Claim to Fame: Raystown is known as the "Striped Bass Capital of the Northeast." The current state record Striper, weighing over 53 pounds, was pulled from these waters.
5. Lake Wallenpaupack: The Pocono Powerhouse
Located in the Pocono Mountains, "The Pack" is a man-made reservoir covering 5,700 acres with 52 miles of shoreline.
- Primary Targets: Striped Bass (Hybrids and Pures), Smallmouth Bass, and Walleye.
- 2026 Outlook: Recent surveys show a booming population of hybrid striped bass, making it a favorite for night fishing during the summer months.
Honorable Mentions: The "Best of the Rest"
While they don't hit the 5,000-acre mark, these lakes are massive by Pennsylvania standards and offer exceptional fishing:
- Shenango River Lake (3,560 acres): A top-tier destination for Hybrid Striped Bass and Crappie.
- Lake Arthur (3,225 acres): Located in Moraine State Park, it is legendary for its Hybrid Striped Bass and massive Channel Catfish.
- Conneaut Lake (928 acres): Notable because it is the largest natural lake in Pennsylvania, offering a unique glacial ecosystem for Northern Pike and Bass.
Where Should You Fish PA?
If you want the challenge of big-water navigation and trophy Walleye, head to Lake Erie or Pymatuning. For those hunting for the thrill of a 40-pound Striped Bass in deep mountain water, Raystown Lake is your best bet.
