Green Lake Fishing Guides

Wisconsin's deepest inland lake at well over two hundred feet, cold enough to hold lake trout in the middle of farm country and fished year round for a wide mix of species.

About the Green Lake

Green Lake is the deepest natural inland lake in Wisconsin, dropping to more than two hundred and thirty feet in a state where most lakes are a fraction of that. It covers around seventy three hundred acres in the farmland of the east central part of the state, and its depth is the reason it fishes nothing like its neighbours. The lake stratifies strongly in summer and holds a cold, oxygenated layer through the warm months.

That cold water supports a coldwater fishery that has no business existing this far south in Wisconsin. Lake trout are stocked and hold in the deep basin, and brown trout are present as well. Anglers troll for them in summer using downriggers and lead core, working the thermocline in water that would be far too warm at the surface. It is genuinely unusual to fish lake trout with corn and soybean fields visible on the shore.

The warmwater fishery is equally good and far more accessible. Walleye use the rock bars and the drop-offs, smallmouth bass hold on the extensive gravel and rubble shoreline structure, largemouth work the weedy bays, and northern pike hunt the shallower flats. The lake has clear water and abundant structure, so the fishing is more about locating the right depth and edge than about covering huge distances.

The lake has been a resort destination since the nineteenth century, when steamboats and grand hotels brought visitors up from Chicago and Milwaukee. Much of the shoreline is developed and privately held as a result, and the lake sees substantial recreational boat traffic in summer. Public access is adequate but concentrated at a handful of launches and parks rather than spread around the shore.

Seasons split cleanly. Spring brings walleye and smallmouth into the shallows and offers the best shore-adjacent fishing of the year. Summer sends the trout deep and pushes serious anglers offshore with electronics. Fall is the strongest all-round window as the lake turns over and fish spread out. Winter ice fishing is popular, though the depth means ice forms later and less predictably than on shallower lakes.

This water needs a real photo

The photo at the top of this page is not Green Lake.

It is a regional stand-in, honestly captioned but generic — we will not put a name to a river we cannot prove. Send us a photograph you took here and it replaces the stand-in, with your credit on it.

Access

Green Lake - the city on the north shore, with launches, tackle and services.
Public boat landings around the lake - the main access points, concentrated rather than continuous.
Green Lake County Park - the county park with shoreline and launch access.
Ripon - the nearby town to the northwest.
Fond du Lac - the larger city to the northeast at the foot of Lake Winnebago.
Madison - the nearest metropolitan area, southwest, and the source of much of the traffic.
Fox River - the river system draining the surrounding country.

Seasons

Spring: walleye and smallmouth move shallow and the lake offers its most accessible fishing.
Summer: strong stratification sends lake trout deep, with trolling the offshore basin the main approach.
Fall: turnover spreads fish out and produces the most consistent all-round fishing of the year.
Winter: ice forms later than on shallow lakes, with a solid panfish and pike fishery once it does.
