What You'll Find at Comus Lake

Comus Lake is a shallow, 265-acre impoundment in Walworth County that holds walleye, northern pike, and largemouth bass in a system that rewards patience and timing. The lake averages 8 to 10 feet deep with a maximum depth around 20 feet, making it a different animal from the deeper glacial lakes nearby. Shallow water means the fish move more with light and season, and the weed growth—which can be thick—creates both cover and navigation challenges.

The lake sits in agricultural country, and that character shows in the water. Spring runoff and summer algae blooms are part of the rhythm here. Walleye fishing peaks in spring and fall when the shallow water cools. Pike are present year-round and can be aggressive in the shallows, especially early season. Bass fishing is secondary but steady, particularly around structure and weed edges.

Key Takeaways

  • Comus Lake is a shallow 265-acre lake best known for walleye and northern pike in depths that rarely exceed 20 feet.
  • Spring and fall offer the most consistent walleye action, while pike remain catchable throughout the open-water season.
  • Weed growth is heavy and changes the character of the lake; summer fishing requires navigation around vegetation and patience with timing.
  • Public boat access is available, and the lake is close enough to Milwaukee and Chicago for a day trip from the southern Wisconsin region.

Walleye Fishing: Spring and Fall Patterns

Walleye on Comus Lake respond to the shallow-water calendar. In spring, as the water warms from 40 to 55 degrees, walleye move into the shallows to feed and spawn. Early morning and evening are prime, but on overcast days the bite can extend through midday. Jigs tipped with live minnows or soft plastics work well along the deeper weed edges and any hard-bottom areas you can locate. The lake's shallow profile means walleye don't have to move far to find food, so they concentrate in predictable zones.

Fall brings a second strong bite as water temperatures drop again. September and October are often better than spring because the fish are feeding aggressively before winter and the weed growth hasn't completely died back. Night fishing with live bait can be productive, and some anglers have success with crankbaits that mimic the small fish the walleye are chasing. Summer walleye fishing is possible but requires fishing early, late, or during low-light periods; midday heat pushes them deeper into whatever structure exists.

Northern Pike: Year-Round Opportunity

Pike are the lake's most forgiving fish. They're present from ice-out through fall and will chase lures in shallow water when walleye are inactive. Early season—April and May—is excellent for pike; they're aggressive after spawning and willing to hit larger presentations. Spinnerbaits, large soft plastics, and topwater lures all draw strikes. The shallow weed edges are pike territory, and a 6- to 7-foot medium-heavy rod with 15- to 20-pound braid gives you the backbone to work through vegetation.

Summer pike fishing slows but doesn't stop. Fish the early morning hours and focus on the deepest water available—the 15- to 20-foot zone—where pike retreat from the heat. Live bait presentations, particularly larger shiners or herring, can produce. Fall pike fishing picks up again as water cools, and October can rival spring for consistent action.

Weed Growth and Navigation

Comus Lake's shallow profile supports dense weed growth, particularly in summer. Cabbage, coontail, and other submergent vegetation create excellent fish habitat but make navigation and fishing challenging. The weeds can be so thick in July and August that some areas become nearly unfishable. Early season and late season—before and after peak weed growth—offer clearer water and easier access to structure.

If you fish during heavy weed growth, focus on weed edges rather than trying to fish through the middle. The transition zone between open water and dense vegetation is where fish hunt. A weedless jig or a soft plastic rigged on a wide-gap hook helps you work the edge without constant snagging. Bring extra tackle; you will lose some to vegetation.

Access and Boat Ramps

Public boat access is available on Comus Lake through a town ramp. The ramp is basic but functional for small to medium-sized boats. Parking is limited, so arrive early on weekends. The lake is shallow enough that a 15- to 18-foot boat with a standard outboard works well; a trolling motor is nearly essential for navigating the weed growth and fishing shallow structure. Canoes and kayaks can launch here too, though the open water and occasional wind can make paddling challenging.

The lake is roughly 45 minutes south of Milwaukee and about 90 minutes north of Chicago, making it accessible for a day trip from either metro area. Walworth County has other lakes nearby—Delavan, Como, and Lauderdale—so you can plan a multi-lake trip if conditions on Comus aren't ideal.

Seasonal Timing and Weather Patterns

Spring fishing on Comus Lake is best from mid-April through May, after ice-out and as water temperatures climb into the 50s. Early mornings and overcast days are most productive. Summer (June through August) is challenging for walleye but can be good for pike in early morning. The weed growth peaks in July and August, limiting access to some areas.

Fall is the most reliable season. September and early October offer consistent walleye and pike fishing, clearer water, and more comfortable weather. By late October, the bite slows as water temperature drops below 50 degrees. Winter fishing is possible through the ice, but Comus Lake is not known as a premier ice-fishing destination compared to other Walworth County lakes.

What to Bring and How to Prepare

Pack a weedless jig assortment (1/4 to 3/8 ounce), soft plastics in natural colors (browns, blacks, whites), and live minnows or shiners if you plan to fish live bait. Bring extra tackle; the weeds will claim some. A GPS or mapping app showing weed beds and depth contours is helpful, though the lake is small enough to learn by fishing it a few times.

Check Wisconsin Department of Natural Resources regulations for current season dates, size limits, and bag limits before you go. Walleye and pike regulations can change year to year. Comus Lake does not have special restrictions beyond state-wide rules, but it's worth confirming. Bring sunscreen, water, and a hat; the shallow water and open shoreline offer little shade.

Frequently Asked Questions

Is Comus Lake good for beginners?

Yes, if you fish in spring or fall. The shallow water and presence of pike make it forgiving—pike will chase lures when walleye are inactive. Summer fishing requires more skill and timing. The weed growth can be frustrating for someone still learning to navigate structure, so spring is the best season to start.

Can you fish Comus Lake from shore?

Shore fishing is possible but limited. The lake has some public shoreline access, but most productive fishing requires a boat to reach weed edges and deeper structure. If you don't have a boat, focus on early morning or evening when fish move shallower, and fish the clearest water you can find.

What's the best time of day to fish Comus Lake?

Early morning (sunrise to mid-morning) and evening (late afternoon through dusk) are most productive for walleye. Pike will bite throughout the day but are more aggressive in low-light periods. On overcast days, the bite can extend through midday. Summer fishing requires early morning or night to avoid the heat pushing fish deep.

Do I need a trolling motor?

A trolling motor is nearly essential. The shallow water and weed growth make it difficult to fish effectively with only an outboard. A 55- to 70-pound thrust motor is sufficient for a lake this size. It also lets you cover water quietly and position yourself precisely on structure.

What's the difference between Comus Lake and other Walworth County lakes?

Comus is shallower and weedier than Delavan or Como, which makes it better for pike and spring walleye but more challenging in summer. Delavan is deeper and holds walleye year-round. Lauderdale is similar in character to Comus. Choose based on season and what you want to catch.
