What Bush Lake offers anglers

Bush Lake is a shallow, weedy walleye and northern pike lake in Otter Tail County, just outside Fenton in central Minnesota. The lake runs about 350 acres and averages 8 to 10 feet deep, with a maximum depth around 20 feet—typical of the prairie lakes that dot this region. The shallow structure and abundant aquatic vegetation make it a strong producer for walleye in spring and fall, and pike year-round, though the lake also holds bluegill, crappie, and some largemouth bass.

What sets Bush Lake apart from deeper coldwater lakes is its seasonal rhythm. Summer can be challenging because the shallowness and weed growth create low-oxygen conditions in the heat, pushing walleye into the deepest holes or out of the lake entirely. Spring and fall are the prime windows—water temperatures stay in the comfortable range for walleye activity, and the weeds haven't yet choked out access to structure. Winter fishing is solid for both walleye and pike if you can find open water or are willing to cut through ice.

Key Takeaways

  • Bush Lake is a 350-acre shallow prairie lake best fished in spring and fall when walleye are most active across the structure.
  • Weeds dominate the lake, so you will need to fish edges, holes, and channels rather than open water—a boat with good shallow-water capability is nearly essential.
  • Summer fishing is difficult because low oxygen pushes walleye deep or out of the lake, but pike remain catchable in the weeds.
  • Winter access depends on ice thickness and whether the lake is frozen solid enough for safe travel; check local conditions before heading out.
  • A Minnesota fishing license is required, and the lake follows standard state regulations for walleye (daily limit, size restrictions) and pike.

Spring walleye fishing on shallow structure

Spring is when Bush Lake shines for walleye. As water temperatures climb from the low 40s into the 50s, walleye move out of the deepest winter holes and begin feeding along the weed edges, shallow rock piles, and channel breaks. The lake's shallow profile means walleye don't have to travel far to find food, so they concentrate in predictable zones.

Target the weed edges first—anywhere vegetation transitions from thick to sparse or from shallow to deeper water. Jigs tipped with live minnows or soft plastics work well in 6 to 12 feet of water. Early morning and late evening produce better than midday, but on overcast spring days walleye can bite throughout the afternoon. If you're fishing from shore, focus on the deeper holes and channels; a boat gives you access to the mid-lake structure that holds the bulk of the population.

Trolling crankbaits along weed lines is also effective in spring, especially if you have a GPS unit to mark the edges. The key is staying shallow enough to trigger strikes but deep enough that walleye aren't spooked by your boat. Many anglers use a trolling motor to move slowly and quietly rather than a main engine.

Fall fishing and the transition to winter

Fall mirrors spring in many ways—water cools, oxygen levels improve, and walleye spread across the lake again. September and October are often the most consistent months because the lake hasn't yet iced over and the fish are feeding aggressively in preparation for winter. The same jig-and-minnow approach works, though you may find walleye in slightly deeper water (10 to 15 feet) as the season progresses.

Pike fishing also peaks in fall. The cooler water energizes them, and they hunt more actively in the weeds. Large topwater lures and soft plastics in the 4- to 6-inch range draw strikes. Pike on Bush Lake typically run 24 to 30 inches, with occasional fish pushing into the 35-inch range—solid fish for a lake this size.

By late October and November, ice begins to form. Check local reports and talk to bait shops in Fenton before heading out; ice thickness changes week to week, and you need at least 4 inches to walk safely and 5 to 6 inches for a snowmobile or small vehicle.

Summer conditions and pike opportunities

Summer on Bush Lake is tough for walleye but manageable for pike. The shallow water warms quickly, and the dense weed growth consumes oxygen, especially at night. Walleye retreat to the deepest holes (around 18 to 20 feet) or leave the lake entirely for deeper, cooler water nearby. If you're determined to fish walleye in July and August, focus on those deep holes at dawn and dusk, and expect slower action than spring or fall.

Pike, however, thrive in the weeds. They're ambush predators and don't mind warm, weedy water the way walleye do. Fish heavy cover—the thickest weed beds and any open pockets within them. Throw large lures that displace water and create vibration: spinnerbaits, buzzbaits, and large soft plastics. Early morning and evening are still best, but pike will bite midday if you're fishing heavy enough cover.

Winter ice fishing for walleye and pike

Once the lake freezes solid, Bush Lake becomes a different fishery. Walleye congregate in the deeper holes and along channel breaks, and they're often less active than in open water—the cold and low light reduce feeding. Tip-ups baited with live minnows work well, as do small jigging spoons worked slowly near the bottom. Patience is part of winter fishing; you may spend hours for a few bites, but the fish you catch are often larger than summer fish.

Pike remain aggressive under the ice. They hunt in the weeds and along edges, and they respond well to larger baits and lures. Many anglers use tip-ups with 6- to 8-inch minnows and catch pike consistently throughout the winter. The challenge is access—if the lake isn't frozen thick enough or if snow cover makes travel difficult, you may need to fish from shore or skip the lake that week.

Boat access and shore fishing options

Bush Lake has a public boat launch on the north side, accessible from County Road 40 near Fenton. The launch is a single-lane gravel ramp suitable for small to mid-size boats. Parking is limited, so arrive early on weekends. The lake is shallow enough that a 15- to 18-foot boat with a shallow-draft motor is ideal; deep-V hulls can run aground in some areas.

Shore fishing is possible but limited. The north side near the launch offers some access, and there are a few spots along the east shore where you can reach the water. However, much of the shoreline is private property or thick with vegetation, so a boat is nearly essential if you want to fish effectively. If you don't have a boat, ask at local bait shops in Fenton about rental options or guide services.

Regulations and licensing

Bush Lake follows Minnesota state fishing regulations. You need a valid Minnesota fishing license, available online through the Minnesota Department of Natural Resources website or at any bait and tackle shop. Walleye have a daily limit of six fish with a 15-inch minimum size. Northern pike have a daily limit of three fish with a 24-inch minimum size. Bluegill and crappie have a 25-fish daily limit with no size restriction.

The lake is open year-round for fishing, but winter access depends on ice conditions. Check with the Otter Tail County Sheriff's Office or local bait shops before heading out in winter; they can tell you whether the ice is safe for travel.

Frequently Asked Questions

What's the best time of year to fish Bush Lake?

Spring (April through May) and fall (September through October) are the most consistent. Water temperatures are ideal for walleye activity, oxygen levels are good, and the fish are spread across the lake rather than concentrated in deep holes or absent entirely. Summer is challenging for walleye but good for pike.

Do I need a boat to fish Bush Lake?

A boat makes fishing much more productive because the lake is shallow and weedy, and most of the structure is mid-lake. Shore fishing is possible but limited to a few spots. If you don't own a boat, check with bait shops in Fenton about rentals or guide services.

What size pike and walleye does Bush Lake produce?

Walleye typically run 14 to 18 inches, with some fish pushing 20 inches. Pike average 24 to 30 inches, with occasional fish in the 35-inch range. The lake is not known for trophy fish, but it's a solid producer of keeper-size fish in both species.

Is Bush Lake good for beginners?

Spring and fall are beginner-friendly because walleye are active and spread across the lake. Summer and winter require more experience and patience. If you're new to fishing, hire a guide for your first trip—they can teach you the structure and help you understand the seasonal patterns.

Can I fish Bush Lake in winter?

Yes, but only when ice is thick enough—at least 4 inches to walk safely, 5 to 6 inches for a vehicle. Check local conditions and ice reports before heading out. Winter fishing is slower than open water but can be productive if you're patient and fish the deep holes.
