Features
Pewaukee Lake is popular with Milwaukee anglers and receives heavy recreational use throughout the year, especially during summer. The lake is recognized as one of the premier muskie lakes in southern Wisconsin. The lake is separated into two distinct and unique basins, east and west of the Narrows. The deeper west basin is the original lake, while the east basin was created when a 6 foot dam was built across a small outlet stream going through a former marsh.
Forage
White sucker, sheepshead, common shiner, emerald shiner, golden shiner, bluntnose minnow, brook silverside and crayfish offer a diverse forage base for predatory species. Panfish (perch, bluegill and crappie) are abundant and forming the bulk of the forage. Juvenile carp and sheepshead are extremely important forage for muskie and northern pike. Rusty crawfish, an exotic species, are present.
