What Big Lake Offers and When to Fish It

Big Lake sits in Sherburne County near Princeton, Minnesota, and holds walleye, northern pike, and panfish in a shallow, weedy system that rewards anglers who understand structure and timing. The lake runs roughly 1,200 acres and averages 8 to 12 feet deep, with extensive weed beds that make summer fishing challenging but productive during spring and fall. Walleye bite best in May and June before the weeds thicken, and again in September and October as water cools. Pike are present year-round but most active in spring and fall. Bluegill and crappie provide consistent action in summer if you fish the deeper holes and weed edges.

Access is straightforward: a public boat launch sits on the north shore off County Road 5, with parking for roughly a dozen vehicles. The launch has a concrete ramp and is maintained by Sherburne County. No resort or rental fleet operates on Big Lake, so bring your own boat or fish from shore along the public access points near the launch.

Key Takeaways

  • Big Lake is a shallow, weedy system best fished in spring (May–June) and fall (September–October) when walleye and pike are most active.
  • The public boat launch on County Road 5 is the main access point; no rental boats or resorts operate on the lake.
  • Summer panfish action is reliable in deeper holes and along weed edges, but walleye fishing becomes difficult once weeds fully develop.
  • Minnesota fishing licenses and regulations apply; check current rules for walleye and pike bag limits before you fish.

Spring Walleye and Pike Fishing (May Through June)

Spring is the prime window for walleye on Big Lake. Water temperatures in May and June hover in the 55–65 degree range, and walleye move shallow to feed before spawning and before the weed beds become impassable. Fish the transition zones where deeper water meets the flats—typically 6 to 10 feet deep—using live shiners or crawlers on jigs or slip-sinker rigs. Early morning and late evening produce best, but overcast days often hold fish throughout the day.

Pike fishing peaks in the same window. They hunt actively in spring and are less deterred by weeds than walleye. Throw large swimbaits, spinnerbaits, or crankbaits along the weed edges and in the deeper holes. The north and east sides of the lake tend to hold more pike structure than the shallower western end.

Summer Panfish and Deeper-Water Tactics

By July, the weed beds on Big Lake become so thick that walleye fishing is nearly impossible for most anglers. Panfish, however, thrive in summer. Bluegill and crappie congregate in the deeper holes—look for water 12 to 16 feet deep—and around the weed edges where they hunt smaller baitfish. Drop a jig tipped with a small minnow or maggot and work it slowly. Early morning and dusk are most productive, but midday can work if you find the right depth.

Some walleye remain in the deepest holes during summer, but they are lethargic and difficult to target consistently. If you want walleye in July and August, focus on night fishing with live bait in the deepest water you can find, or wait for fall.

Fall Fishing (September and October)

Fall is the second-best season on Big Lake. As water cools in September and October, weeds begin to die back, and walleye and pike move shallower again to feed heavily before winter. Walleye fishing improves dramatically in late September and holds strong through October. Use the same tactics as spring—jigs with live bait, slip-sinker rigs, and crankbaits—but fish slightly deeper (8 to 14 feet) as the season progresses and water continues to cool.

Pike are equally aggressive in fall. Larger fish move into shallower water to hunt, making fall an excellent time to target trophy pike. Throw large baits and lures, and do not be afraid to fish the weed edges aggressively.

Winter Access and Ice Fishing

Big Lake freezes reliably by mid-December and remains fishable through February. The shallow depth means ice-out can be sudden in March, so check local conditions before heading out in late winter. Ice fishing for walleye and pike is possible, though the shallow system means fish are spread across the lake rather than concentrated in deep holes. Panfish are more predictable under the ice; bluegill and crappie hold in the same deeper holes they occupy in summer.

The boat launch area is not plowed in winter, so park on the road and walk to the ice. Always check ice thickness before driving or walking far from shore.

Regulations and Licensing

Minnesota fishing licenses are required for all anglers 16 and older. Purchase a license online through the Minnesota Department of Natural Resources website or at any authorized vendor. Walleye and pike have specific bag limits and size restrictions that vary by year and region; check the current Minnesota fishing regulations before you fish. Big Lake falls under the general statewide rules, not a special regulation zone, so standard limits apply.

Panfish have generous limits and no size restriction, making them a good option for families or anglers who want to keep fish for a meal.

What to Bring and How to Prepare

Bring a boat with a shallow-water motor or trolling motor—Big Lake's shallow depth and weed beds make a 9.9-horsepower or smaller motor ideal. A GPS or map is helpful for finding the deeper holes and navigation channels through weeds. Polarized sunglasses help you spot structure and weed lines in the clear water.

Tackle should include jigs (1/4 to 3/8 ounce), live shiners and crawlers, slip-sinker rigs, spinnerbaits, and crankbaits. Bring extra line; the weeds and rocks will catch and break it. A net is useful for landing pike and larger walleye.

Weather on Big Lake can change quickly. Bring rain gear and dress in layers, especially in spring and fall. The shallow water means the lake can get rough in wind, so check the forecast before launching.

Frequently Asked Questions

Can I fish Big Lake from shore?

Yes, shore fishing is possible near the public boat launch and along County Road 5, but a boat gives you access to deeper water and weed edges where fish are more concentrated. Shore fishing works best in spring and fall when walleye move shallow.

What is the best lure for walleye on Big Lake?

Live bait on a jig or slip-sinker rig outproduces artificial lures on Big Lake. If you prefer lures, small crankbaits (2 to 3 inches) and spinners work in spring and fall. Summer requires live bait in deep water.

Is there a resort or rental boats on Big Lake?

No. Big Lake has no resort, rental fleet, or lodging. The nearest services are in Princeton, about 5 miles away. Bring your own boat or fish from shore.

When do the weeds get too thick to fish?

Weeds typically become impassable by mid-July and remain thick through August. By late September, they begin to thin, and by October the lake is mostly fishable again.

What is the water clarity like on Big Lake?

Big Lake has clear to slightly stained water, which is typical for shallow Minnesota lakes. Visibility is usually 3 to 6 feet, making polarized sunglasses useful for spotting fish and structure.
