Pictured above: Screenshots from the publicly available videos showing the disturbance of the lake bottom and water column by a passing wake boat. This is just a quick example of findings from the Saint Anthony Falls Laboratory (SAFL) Wake Study, Phase II.

“A Field Study of Recreational Powerboat Hydrodynamics and their Impacts on the Water Column and Lakebed” from the University of Minnesota, St. Anthony Falls Laboratory

The report of this long-anticipated study, which we have also referred to as SAFL Phase II, was just released this week. This research was funded in part by MLSA and many of you who are seeking answers for what is happening below the surface in our lakes during wake boat activity.

Spoiler Alert: “It is recommended that wakeboats operate in 20 ft of water or greater when in surfing mode to minimize impacts on the lake bottom.”

We invite you to review the information and attend the upcoming webinar about these findings.
