Features

Lake Monona is located in south central Wisconsin, with the cities of Madison and Monona bordering the lake. Vegetation is abundant along much of the shoreline, offering excellent habitat for fish, and opportunities for shore anglers. Despite the metropolitan setting, there are several public parks that are very accessible for shore anglers. The lake is highly used for many recreational activities. As a very large, open body of water, heavy winds and heavy recreational use can create large unpredictable waves on the lake. Take caution when operating smaller watercraft on the lake. The Wisconsin DNR regulates the lake’s fishery through harvest regulations and stocking efforts. Check the current Wisconsin DNR fishing regulation manual for size requirements and daily bag limits.

Forage

Northern brook silverside, bluntnose minnow and both common and golden shiners make up a portion of the forage base. White sucker and juvenile panfish provide an excellent forage base for large predator species.

Seasonal Movements

Several species make spawning runs to the Yahara River, including: white bass, crappie, northern pike and walleye. Northern pike tend to concentrate spawning near Upper Mud Lake. Spring water levels can affect the movement to these areas.
