Lake Profile
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.
 Anglers seek game fish species including largemouth bass, northern pike, and walleyes as well as several panfish species.


 Acquired in 1969.

This seven-acre community park contains:

  • a boat launch (Little Muskego Lake)
  • a fishing pier 
  • picnicking 
  • indoor restrooms May-September and portable restrooms during off-season
  • concession sales and rental equipment

For more information on the park, please see the Idle Isle Park information here.

Launch fees at Idle Isle (paid at the electronic pay stations) are determined by the boat size.
