What You'll Find at Upper Bass Lake

Upper Bass Lake is a shallow, weedy impoundment in central Wisconsin that holds largemouth bass, bluegill, and crappie. The lake sits in a chain with Lower Bass Lake, connected by a narrow channel, and the entire system rarely exceeds 15 feet deep. Weed growth is heavy — especially in summer — which makes this a good destination for anglers targeting bass in vegetation and panfish in the shallows.

The lake covers roughly 500 acres and draws local and regional anglers rather than long-distance travelers. Access is straightforward, regulations are standard Wisconsin rules, and the season runs year-round for most species. Spring and fall tend to produce the most consistent fishing, though summer can be productive early and late in the day when weeds are thickest.

Key Takeaways

  • Upper Bass Lake is a shallow, weedy system best suited to anglers targeting largemouth bass in vegetation and panfish in open pockets.
  • Public boat launch access is available at the north end of the lake, with parking for trailers and a paved ramp.
  • Spring (April through May) and fall (September through October) are the most reliable seasons, with summer requiring early morning or evening trips to avoid dense weed mats.
  • Wisconsin fishing regulations apply: a valid state license is required, and largemouth bass have a 12-inch minimum size limit with a daily bag limit of five fish.
  • Shallow-running crankbaits, soft plastics in the 4- to 6-inch range, and small jigs work well in the weeds; panfish respond to live bluegill and small spinners.

Seasons and What to Expect

Spring (April through May) is when Upper Bass Lake fishes best. Water temperatures climb from the low 50s to the mid-60s, bass move shallow to spawn, and weeds are just beginning to fill in. Largemouth bass position themselves along weed edges and in shallow bays, making them easier to locate than in midsummer. Bluegill and crappie also move into the shallows to spawn, and panfish fishing can be excellent around dock pilings and emerging vegetation.

Summer (June through August) brings dense weed growth that can make navigation difficult. Bass retreat to deeper pockets within the weeds or to the channel connecting Upper and Lower Bass Lake. Early morning and late evening trips — before 9 a.m. or after 6 p.m. — are more productive than midday. Weed-specific techniques like flipping and pitching become necessary. Panfish scatter into deeper water but can still be found around structure.

Fall (September through October) rivals spring for consistent fishing. Weeds begin to thin, water temperatures drop into the 60s and 50s, and bass feed aggressively before winter. This is an excellent time for both largemouth and panfish. The lake is less crowded than in summer, and the cooler weather makes full-day trips more comfortable.

Winter (November through March) allows ice fishing when the lake freezes solid, typically by mid-December. Largemouth bass fishing slows considerably, but panfish — especially bluegill and crappie — remain active under the ice. Check ice thickness and local conditions before heading out; the Wisconsin Department of Natural Resources publishes ice safety guidelines each season.

Access and Boat Launch Information

Upper Bass Lake has one public boat launch located at the north end of the lake, accessible via County Road A. The ramp is paved, maintained by the local town, and accommodates both single and double trailers. Parking is available in a dedicated lot adjacent to the ramp, with space for roughly 20 vehicles and trailers. There is no launch fee.

The ramp is open year-round, though winter access depends on snow removal and ice conditions. During heavy snow, call the town office to confirm the lot has been plowed. The launch is busiest on weekends in spring and fall; weekday mornings offer quieter conditions.

Shore fishing is possible at several points around the lake, though much of the shoreline is private residential property. A small public access area exists on the west side near the channel to Lower Bass Lake, with limited parking and no facilities. Canoe and kayak access is available at the boat launch; the shallow, weedy nature of the lake makes it suitable for small craft, though navigation can be slow in summer.

Largemouth Bass Fishing Tactics

Largemouth bass in Upper Bass Lake respond well to weed-specific presentations. In spring and fall, when weeds are thinner, shallow-running crankbaits (1 to 3 feet deep) and topwater plugs work along weed edges and in open pockets. Cast parallel to weed lines rather than into them, and work the lure slowly to trigger strikes.

Summer fishing requires flipping and pitching soft plastics — 4- to 6-inch worms, crawfish imitations, or creature baits — directly into dense weed mats. Use a 7-foot medium-heavy rod with 20- to 30-pound braided line to muscle fish out of the vegetation. Jigs tipped with soft plastics also work well; hop them along the bottom in deeper pockets within the weeds.

The channel connecting Upper and Lower Bass Lake is a natural funnel where bass congregate, especially during transitions between seasons. Fish this area thoroughly in spring and fall. Early morning and late evening produce more strikes than midday, regardless of season.

Panfish and Crappie Opportunities

Bluegill and crappie are abundant in Upper Bass Lake and often overlooked by anglers focused on bass. In spring, both species move into shallow bays and around dock pilings to spawn; live bluegill or small minnows under a bobber work well. Crappie also respond to small jigs (1/8 to 1/4 ounce) tipped with minnows or soft plastics.

Summer panfish retreat to deeper water and structure. Fish around submerged logs, dock supports, and the deeper portions of the channel. Small spinners and in-line spinners in silver or gold are effective, as are live minnows suspended at 8 to 12 feet. Evening trips often produce better results than midday.

Fall panfish fishing improves as water cools and fish move back into shallower areas. This is an excellent time to target crappie around the channel and in open pockets within the weeds. Winter ice fishing for panfish can be productive; small jigging spoons and live minnows under the ice attract bluegill and crappie throughout the season.

Wisconsin Regulations and Licensing

A valid Wisconsin fishing license is required for anyone 16 years or older. Licenses are available online through the Wisconsin Department of Natural Resources website, at sporting goods retailers, and at town offices. A daily license costs less than a full-season license and is useful for occasional visitors.

Largemouth bass have a 12-inch minimum size limit and a daily bag limit of five fish. Bluegill and crappie have no minimum size limit and a daily bag limit of 25 fish combined. These regulations apply statewide and are enforced by the DNR and local conservation wardens.

The lake is open to fishing year-round, though some access points may be closed seasonally. Check current regulations before your trip; the Wisconsin DNR website publishes updates and any temporary closures. Catch-and-release is encouraged, especially for largemouth bass, to maintain the fishery.

Nearby Amenities and Lodging

Upper Bass Lake is located in a rural area with limited immediate amenities. The nearest town with gas, food, and lodging is roughly 10 to 15 miles away, depending on your location on the lake. Several small resorts and cabin rentals operate in the region; booking in advance is recommended, especially during spring and fall.

Camping is available at nearby state and county parks. The closest public campground with full facilities is typically 15 to 20 miles from the lake. Day-trip anglers should plan to bring food and water, as there are no concessions at the boat launch.

Frequently Asked Questions

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

Spring (April through May) and fall (September through October) are most consistent. Water temperatures are moderate, weeds are manageable, and both bass and panfish are active. Summer can work early and late in the day, but dense weeds make midday fishing difficult.

Can I fish Upper Bass Lake in winter?

Yes. Ice fishing for panfish is productive once the lake freezes solid, typically by mid-December. Largemouth bass fishing slows in winter but is still possible. Always check ice thickness and local conditions before heading out.

Do I need a boat to fish Upper Bass Lake?

A boat is helpful but not required. The public boat launch provides access, but shore fishing is possible at limited locations on the west side. Canoes and kayaks work well for exploring shallow areas, though summer weed growth can slow navigation.

What size lures and baits work best?

For bass, use 4- to 6-inch soft plastics, shallow-running crankbaits, and jigs. For panfish, small jigs (1/8 to 1/4 ounce), live bluegill, and small spinners are effective. Live minnows under a bobber work well for crappie in spring.

Is there a launch fee at Upper Bass Lake?

No. The public boat launch at the north end is free and maintained by the local town. Parking is available in a dedicated lot adjacent to the ramp.
