What Whalon Lake offers and who should fish it
Whalon Lake is a 42-acre impoundment in Will County, about 35 miles southwest of Chicago near the town of Lockport. The lake holds largemouth bass, bluegill, crappie, and channel catfish, making it a solid choice for anglers targeting panfish or bass in a smaller, less crowded setting than many other Illinois lakes. The water is relatively shallow and weedy in places, which concentrates fish and makes it easier to locate them, especially in spring and early summer.
The lake works best for bank fishing and small boats. There is a public boat launch on the north side, and the shoreline is accessible from several points. If you fish from shore, expect to wade or cast from the bank into water that ranges from 8 to 15 feet deep in most areas. The lake draws fewer anglers than Chain O'Lakes or Pistakee Lake to the north, so you will have more room to work and less pressure on the fish.
Whalon is a good destination if you want a half-day outing close to the Chicago area, or if you are new to bass or panfish fishing and prefer a smaller, more manageable water. It is not the place to come if you are after trophy-sized fish or looking for deep-water structure and open water.
Key Takeaways
- Whalon Lake holds largemouth bass, bluegill, crappie, and channel catfish in a 42-acre setting with public access via a boat launch and bank-fishing spots.
- Spring and early summer are the most productive seasons, when panfish move shallow and bass become active after spawning.
- You will need a valid Illinois fishing license, and the lake is open year-round, though winter fishing is limited by weather and ice.
- The lake is located in Will County near Lockport, about 35 miles southwest of downtown Chicago, with parking and facilities at the public access area.
- Bank fishing is productive here, especially along weedy margins and near the inlet on the north end, where current and structure hold fish.
Seasons and what fish are active when
Spring (March through May) is the prime season at Whalon Lake. Largemouth bass move into shallow water to spawn, and bluegill and crappie follow the warming water. You will have the best success fishing early morning or late evening, targeting the weedy shallows on the north and west sides of the lake. Spinnerbaits, soft plastics, and small crankbaits work well for bass; panfish respond to live minnows, small jigs, and crickets.
Summer (June through August) slows down as water temperatures climb and fish move deeper or seek shade in weed beds. Early morning and dusk remain your best windows. Bluegill and crappie will be in deeper water or under vegetation; bass may suspend in the middle of the lake. Channel catfish become more active at night, so consider an evening or night trip if you want to target them with cut bait or chicken liver.
Fall (September through November) brings another active period as water cools and fish move back into shallower feeding zones. Bass and panfish are less selective and will hit a wider range of lures and baits. This is a good time for both boat and bank anglers.
Winter (December through February) is slow and often difficult due to ice. The lake may freeze solid, closing boat access. Bank fishing is possible on open-water days, but fish are sluggish and concentrated in the deepest holes. Many anglers skip Whalon in winter and head to larger lakes or indoor facilities.
How to reach Whalon Lake and where to park
Whalon Lake is located at 17540 W. 135th Street in Lockport, Illinois. From Chicago, take Interstate 55 south toward Joliet, then exit onto Route 66 heading south. Follow local roads west toward Lockport; the lake is on the south side of town. GPS coordinates are approximately 41.5667° N, 88.0833° W if you are using a navigation app.
There is a public boat launch and parking area on the north side of the lake, managed by the Will County Forest Preserve District. Parking is free, and the lot typically has space for 20 to 30 vehicles. The launch ramp is concrete and suitable for small boats and kayaks. Bank-fishing access is also available from the parking area and from a few other spots along the shoreline, though some sections are private property—stick to marked public areas.
The drive from downtown Chicago takes about 45 minutes to an hour depending on traffic. From the suburbs closer to Joliet or Lockport, it is 15 to 25 minutes. There are no services directly at the lake, so bring water, snacks, and any tackle you think you will need. The nearest gas and food are in Lockport, about 5 miles away.
Regulations, licensing, and what you need to bring
You must have a valid Illinois fishing license to fish Whalon Lake. Licenses are sold online through the Illinois Department of Natural Resources website, at sporting goods stores, and at some bait shops. A one-day license costs less than a full-year license if you are only making one trip. Children under 16 do not need a license if they are supervised by a licensed adult.
There are no special restrictions on Whalon Lake beyond standard Illinois regulations. Bass have a 12-inch minimum length limit and a daily bag limit of 5 fish. Bluegill and other panfish have no minimum size but a daily limit of 50 fish combined. Channel catfish have no size limit and a daily limit of 50 fish. Check the current Illinois fishing guide before you go, as regulations can change.
Bring a fishing license (physical or digital copy on your phone), a valid form of identification, and appropriate tackle for the species you are targeting. A small tackle box with soft plastics, jigs, spinners, and live bait options will cover most situations. If you are launching a boat, make sure it is registered and that you have a life jacket on board. Bank anglers should wear polarized sunglasses to see fish in the water and bring a net if you plan to keep fish.
Best techniques and where to cast
The north end of Whalon Lake, near the inlet, is the most productive area. Current and fresh water attract and concentrate fish, especially in spring and fall. Cast spinnerbaits and crankbaits along the inlet channel and around any submerged logs or brush. If you are fishing from the boat launch area, work the shallow weedy margins to your left and right before moving out into deeper water.
The west side of the lake has extensive weed beds that hold bass and panfish year-round. In spring and early summer, fish the edges of the weeds with soft plastics rigged Texas-style or on a jighead. In summer, when fish go deeper, try a weedless frog on top of the vegetation or a deep-diving crankbait in the open pockets between weed clumps.
For panfish, live minnows under a bobber work reliably in spring and early summer. Drop them in 4 to 8 feet of water near weed edges or structure. Small jigs tipped with a minnow or maggot are also effective and allow you to cover more water. Channel catfish respond to cut bait (shad, bluegill, or chicken) fished on the bottom in deeper holes, especially at dusk and night.
Bank anglers should focus on the accessible shoreline near the parking area and any points or coves that jut into the lake. Early morning and late evening are critical—fish are more active and less spooky in low light. A 6- to 7-foot medium-power spinning rod with 8- to 10-pound monofilament or braided line is adequate for everything in the lake.
When the lake is crowded and quieter alternatives nearby
Whalon Lake is rarely crowded compared to Chain O'Lakes or Pistakee Lake, but weekends in May and June can draw more anglers, especially on nice weather days. If you want solitude, fish on weekday mornings or visit in fall or winter. Early morning (sunrise to 9 a.m.) is always quieter than midday.
If Whalon is too busy or you want to explore other options in Will County, consider Horseshoe Lake, a smaller 30-acre lake about 10 miles south near Wilmington. It holds similar species and is even less visited. Busse Lake in Cook County, about 20 miles north, is larger and more developed but also more crowded. For a different experience, Kankakee River offers channel catfish and flathead catfish in a flowing-water setting and is less pressured than most lakes in the region.
What to expect in terms of catch rates and fish size
Whalon Lake is not known for trophy fish, but it is consistent for numbers and average size. Largemouth bass typically run 12 to 16 inches, with occasional fish in the 18- to 20-inch range if you are patient and fish the deeper structure. Bluegill and crappie average 6 to 9 inches and are easy to catch in spring and early summer. Channel catfish run 12 to 18 inches on average and are reliable if you fish the right time and place.
On a good spring or early-summer day, a bank angler can catch 10 to 20 panfish and a few bass. A boat angler with a motor can cover more water and may do better, especially if they focus on the weed edges and structure. Summer and winter are slower; expect fewer fish and longer waits between bites. Fall is solid again as water cools.
The lake is stocked periodically by the Illinois Department of Natural Resources, but it is not a put-and-take fishery. Most fish are wild or have been in the lake long enough to be considered established. This means fish are more selective and require better technique than at heavily stocked lakes, but the fishing is more rewarding.
Frequently Asked Questions
Can I fish Whalon Lake year-round?
Yes, the lake is open year-round, but winter fishing is limited by ice and cold. If the lake freezes solid, boat access is closed. Bank fishing is possible on open-water days, but fish are sluggish and concentrated in deep holes. Most anglers skip winter and return in spring.
Is there a bait shop near Whalon Lake?
There is no bait shop directly at the lake. The nearest options are in Lockport, about 5 miles away. Bring your own tackle and bait, or plan to stop in town before heading to the lake. Many anglers bring live minnows and crickets from home or a Chicago-area shop.
Can I use a kayak or canoe on Whalon Lake?
Yes, kayaks and canoes are allowed and launch from the same ramp as motorboats. The lake is small enough that paddling the entire shoreline takes a few hours. Wear a life jacket and be aware that motorboats have the right of way. Early morning is the calmest and safest time to paddle.
What is the best time of day to fish Whalon Lake?
Early morning (sunrise to 9 a.m.) and late evening (5 p.m. to dark) are most productive. Fish are more active and less spooky in low light. Midday can be slow, especially in summer. Night fishing for channel catfish is also effective if you are willing to stay after dark.
Do I need a boat to fish Whalon Lake, or can I fish from shore?
Bank fishing is productive and requires no boat. The shoreline near the parking area and around the inlet holds fish year-round. A boat allows you to cover more water and reach deeper structure, but it is not necessary for a successful outing, especially in spring and early summer.
