Ashippun Lake Wake Study Update
Abstract
"During the summer of 2023, the Ashippun Lake Protection and Rehabilitation District, in coordination with Southeast Wisconsin Regional Planning Commission, concluded a study of wake boat impacts on this small Southeast Wisconsin lake. Ashippun Lake is relatively small (<100 acres) and shallow (35 ft), and the lake bottom provides a significantly different bathymetric topography between north and south shores. The study investigated comparative wake heights and shoreline turbidity of a speed boat with those of a wake boat operated in wake boarding and wake surfing modes at various distances from shore. Study methodologies closely mimicked those of a recent study from the University of Minnesota. A NOAA calculator provided an estimated wind speed correlate for the various powerboat derived wakes. Results revealed a significant impact of lake bottom contour on wave height at the shore, differences between wake boarding and wake surfing waves, and a modest affect on near shore turbidity.
