Features

Located in south-central Wisconsin, bordered by the city of Madison and several other smaller communities, Lake Mendota is situated in a very urban setting. Several parks and beaches are scattered around the lake in the midst of residential and commercial development. Lake Mendota has been one of the most researched and surveyed lakes in the United States. The Wisconsin DNR has strictly regulated the fishery over the years due to the stocking efforts and immense popularity of the lake. As a result, several species like northern pike, walleye, and largemouth bass have special regulations compared to most Wisconsin lakes. Check the Wisconsin DNR fishing regulations manual for current restrictions. The lake is heavily used for many recreational activities including: fishing, boating, and swimming. Lake Mendota has several excellent locations for shore fishing. Due to the urbanized setting, the lake is at high risk for harmful contaminants as a result of runoff. The state has issued a consumption advisory for larger game species, like walleye and northern pike. 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.

Forage

Northern brook silverside, golden shiner, and emerald shiner comprise a large portion of the forage base. Perch, crappie, and other juvenile panfish are forage for large game species. Large game fish may also prey on cisco, when cisco are abundant.

Seasonal Movements

Several species migrate up the Yahara River inlet to spawn, including: walleye, crappie, northern pike and white bass. Northern pike and a few walleye migrate up Sixmile Creek to spawn in spring. Walleye are known to migrate to Tenney Park Dam, and the south shoreline along UW-Madison campus.
