Here's an August 7, 2025 video .....
www.youtube.com/watch?v=fp6gHrqJwo0 .... on wake surfing stirring up the lake bottom, 4:20-length made by Fox 9 Minneapolis-St. Paul on Lake Minnetonka, Minnesota. Lake Minnetonka has 14,528-acres and is located about 16-miles west of Minneapolis.
Some quotes from this video:
"It is significant. Boats are getting bigger and so that energy is going into the water and impacting the water column and the lake bed."
"You get quite a bit of a disruption, erosion, re-suspension of material and even damage to vegetation. It's like a bomb goes off and that's a really big damage .... aquatic plant communities are fragile."
"They recommend that wakeboats should only operate in surfing mode in waters that are 20-feet deep or greater to minimize impact on the lake bed."
"wakeboats adversely impact lakes ..... releasing nutrients like phosphorous .... leading to excessive algae growth"
