What Half Moon Lake offers anglers

Half Moon Lake sits about 20 miles southeast of Eau Claire and runs roughly 350 acres of shallow, weedy water that holds walleye, northern pike, and largemouth bass. The lake averages 15 to 20 feet deep with extensive weed beds and a soft bottom—classic habitat for walleye in spring and fall, and pike year-round. The character of the lake is fundamentally different from the deeper, clearer systems in the region; Half Moon rewards anglers who understand shallow-water structure and are willing to work vegetation rather than open water.

Public access is available at a boat launch on the south shore, managed by the Eau Claire County Parks Department. The launch has parking for roughly 20 vehicles and a single concrete ramp suitable for small to mid-size boats. There is no fuel dock or bait shop on the lake itself, so plan to fuel and stock supplies in Eau Claire before launching.

Key Takeaways

  • Half Moon Lake is a shallow, weedy 350-acre system best suited to walleye in spring and fall and pike throughout the year.
  • The public boat launch on the south shore is the only access point; arrive early on weekends because parking fills quickly.
  • Walleye bite best at dawn and dusk in May through June and again in September and October; summer fishing is slow and difficult.
  • Pike fishing is consistent year-round in the weed beds, especially in water 8 to 15 feet deep along the edges of vegetation.
  • A Wisconsin fishing license is required; no special stamp is needed for Half Moon Lake.

Spring walleye: May through early June

Walleye move shallow in spring as water temperatures climb from the mid-40s to the low 60s. Half Moon's weed beds begin to green up in late April, and by mid-May the fish are actively feeding in 6 to 12 feet of water along the weed edges and in the scattered deeper holes. The bite is strongest at first light and again in the last hour before dark; midday fishing is rarely productive.

Jigs tipped with live minnows or crawlers work well in the weeds; cast parallel to the vegetation rather than into it, and work the jig slowly along the edge. Crankbaits that reach 8 to 12 feet—particularly those that rattle—can be effective when worked over the weed tops. The bite typically slows by mid-June as water temperatures push into the 70s and walleye retreat to deeper, cooler water or move into the thickest vegetation where they are difficult to reach.

Summer: a slow season for walleye

From late June through August, Half Moon's shallow profile works against walleye anglers. Water temperatures regularly exceed 75 degrees, and walleye retreat into the densest weed cover or the few deeper holes in the lake—typically found in the north-central basin, where depths reach 25 to 30 feet. Fishing during this period requires patience and a willingness to target thick vegetation with heavy jigs or to spend time probing the deeper holes with live bait.

Many anglers shift focus to pike during summer, which remain active in the weeds regardless of temperature. If you do pursue walleye in summer, fish only at dawn or dusk, and concentrate on the thickest weed beds or the deepest water you can find. Expect fewer fish and longer waits between bites.

Fall walleye: September through October

As water temperatures drop in September, walleye move back into the shallower weed beds and become aggressive feeders again. The bite in fall is often better than spring because the fish are feeding heavily to prepare for winter. The same techniques that work in May—jigs with live bait, shallow crankbaits—are effective, and the bite window extends longer into midday than it does in spring.

October is typically the strongest month; water temperatures in the 50s trigger consistent feeding throughout the day, though dawn and dusk remain the most reliable times. By late October, as water temperatures drop into the 40s, the bite slows again and fish begin to move toward deeper winter habitat.

Northern pike year-round

Pike are the most consistent fish on Half Moon Lake and can be caught throughout the year. They hold in the weed beds in all seasons, and the shallow, vegetated character of the lake is ideal pike habitat. In spring and fall, pike are active in 6 to 15 feet of water along weed edges; in summer, they move slightly deeper but remain in or near vegetation.

Spinnerbaits, crankbaits, and soft plastics all produce pike. Cast along weed lines and work lures with a steady retrieve or with pauses and twitches to trigger strikes. Live bait—shiners or small bluegill—fished under a bobber or on a slip rig is also effective, particularly in spring and fall. Pike on Half Moon run 18 to 28 inches on average, with occasional fish exceeding 30 inches.

Largemouth bass and panfish

Largemouth bass inhabit the weed beds and are caught incidentally by pike anglers and by those targeting shallow cover with soft plastics or topwater lures. They are not the primary draw on Half Moon, but a dedicated bass angler can find consistent action in the vegetation, particularly in spring and early summer.

Bluegill and other panfish are abundant in the shallow areas and along the shoreline. They are not typically targeted by serious anglers but provide a good option for children or for a relaxing afternoon of light tackle fishing.

Regulations and licensing

Wisconsin fishing regulations apply on Half Moon Lake. You must have a valid Wisconsin fishing license; a daily or annual license can be purchased online through the Wisconsin Department of Natural Resources website or at most bait and tackle shops in Eau Claire. No special stamp or permit is required for Half Moon Lake.

Walleye have a minimum size of 15 inches and a daily bag limit of five fish. Northern pike have a minimum size of 24 inches and a daily bag limit of one fish. Largemouth bass have a minimum size of 12 inches and a daily bag limit of five fish. Panfish have no size restriction and a daily bag limit of 25 fish. Check the current Wisconsin fishing guide before you fish, as regulations can change.

Frequently Asked Questions

What is the best time of day to fish Half Moon Lake?

Dawn and dusk are most productive for walleye, particularly in spring and fall. Pike can be caught throughout the day but are often more aggressive in low-light conditions. Summer fishing is slow regardless of time of day.

Can I fish Half Moon Lake in winter?

Yes, ice fishing is permitted when the lake is safely frozen, typically from December through February. Walleye and pike are caught through the ice, though the bite is generally slower than in open water. Check ice thickness and local conditions before venturing out.

Is there a bait shop near Half Moon Lake?

No bait shop is located on the lake. Several shops operate in Eau Claire, roughly 20 miles away. Plan to purchase bait and supplies before you launch.

How crowded is Half Moon Lake on weekends?

The lake sees moderate weekend traffic, particularly in spring and fall. The parking area at the south shore launch fills by mid-morning on nice weekends. Arriving early or fishing on weekdays offers a quieter experience.

What size boat do I need for Half Moon Lake?

The shallow depth and weed beds make Half Moon suitable for small to mid-size boats, typically 16 to 20 feet. Larger boats can navigate the lake but may have difficulty in the shallower weed beds. Trolling motors are useful for precise positioning in vegetation.
