Waukesha County Parks is a fee-based park system. The entrance fees help offset the cost of maintaining the parks and lake access sites. You may pay daily fees or purchase an annual entrance sticker online. Retzer Nature Center does not require an entrance fee.

The Pewaukee Lake Access boat launch and site are OPEN.
Both North and South ramps are open for use on May 28, 2022.
To minimize interruption to lake access the launches were reconstructed in two phases so that one launch could remain open through the construction process. Read more about this project here.
There are two other launch accesses to Pewaukee Lake, but parking is limited. See locations on the Wisconsin DNR website. Annual Lake Access Stickers are also valid to access Nagawicka, Nemahbin, and School Section Lakes.
Updated Wed., June 1, 2022
Nagawicka Lake Access may be under construction from September 6 - Fall/Winter of 2022. The parking lot will be open during this time, and access to half of the launch will remain open during construction. Check back for project updates.
Stickers are valid for access at Nagawicka Lake, Pewaukee Lake, Nemahbin Lake, and School Section Lake. (No sticker or daily fee required for lake access at Ashippun Lake.)
Annual Entrance Sticker Permits are available for purchase online or in-person at Waukesha County Park System Administrative Office or at Retzer Nature Center. Please note: The license plate numbers of the vehicle on which the sticker(s) will be placed are required for purchase.
