Little Muskego Lake is a 506 acre flow-through lake with extensive shallow margins and a single deep basin.  The lake has a maximum depth of 65 feet and averages 14 feet deep.  The bottom substrate predominantly consists of silt or muck.  Because of the impounding effects of the outlet dam, originally constructed in 1838, the lake level is approximately eight feet higher and the surface area has more than doubled compared to the original natural lake basin.

 

Residents and visitors to Little Muskego Lake enjoy a variety of lake-related recreational activities including boating, skiing, sailing, and fishing.  The Muskego Waterbugs perform water a water ski show in front of Idle Isle Park each Wednesday evening throughout the summer.  The Muskego Recreation Program holds water-related classes and recreational activities on the lake.  Anglers seek game fish species including largemouth bass, northern pike, and walleyes as well as several panfish species.
