"Own Your Wake" Program promotes responsible control of wakes. Click link: https://www.youtube.com/watch?v=hPS26y6gqa4
Video's 1st Wake Tip: "Minimize repetitive passes. Once you've run a line move on to another area."
This is not feasible for many Lake Minnetonka bays. For example, the distance for one north to south pass on Maxwell Bay is about 1 mile. A wakesurfing boat traveling at 10 mph will make 5 passes in 30 minutes /10 in one hour.

Key Findings:
"Wakeboats should operate in 20 ft of water or greater when in semi-displacement (surfing) mode to minimize impacts on the lakebed."
"When operating in preplaning transition mode and in planing mode, it is recommended that recreational powerboats similar to the ones studied here, should operate in 10 ft of water or greater to minimize impacts on the lakebed."

University of Minnesota St Anthony Falls Lab Study of Waves Key Findings:
Wakesurf boat waves pack up to 9 times more wave energy and up to 12 times more wave power than waves from common recreational boats used for waterskiing, tubing, cruising.
Wakesurfing must be at a distance greater than 575 ft from shore for its waves to attenuate to the same wave energy of a non-wakesurf boat at 200 ft from shore. A distance greater than 600 ft is required for wave power.
Here is a link to the report.
It is not uncommon to have multiple wakesurfing boats operating at the same time, which compounds wave generation.
This is why "Own Your Wake" is not a solution to wakesurfing's negative impact on other recreational activities on many Lake Minnetonka bays.
