Wake Boating Education

MLA Wake Boat Educational Initiative

The Challenge: New Research on Wake Boats

• Local media coverage highlighted the environmental impacts of wake boats on lake ecology. 

• The MLA Board researched the issue and partnered with the advocacy group MN Lakes & Rivers. 

• The University of Minnesota's St. Anthony Falls Labs conducted rigorous, multi-phase fluid mechanics testing.

The Scientific Findings: Waves and Lake Bed Impacts

• Phase 1 (Wave Energy): Wake boats in displacement mode create waves 3x higher and 9x more energetic than standard boats. To match typical recreational boat wave levels, boats must operate at least 500 feet from shore.

• Phase 2 (Depth Impact): Powerful prop wash stirs up lake bottom sediment and uproots vegetation at depths up to 20 feet. Stirred sediment releases phosphorus, causing algae blooms that harm water quality, fish, and property values.

• Phase 3 (Ongoing): Researchers are currently studying near-shore impacts, with results expected in 2026.

The Solution: Actionable Operational Guidelines

• Distance: Keep wake boats in displacement mode at least 500 feet from shorelines, docks, and other watercraft.

• Depth: Only operate in displacement mode in water 20 feet deep or deeper.

• State Integration: Minnesota now includes these distance and depth rules in its mandatory boater safety training.

MLA's Proactive Approach: Education Over Regulation

• Landing Maps: MN Lakes & Rivers and the MN DNR created custom lake maps outlining the safe 500-foot/20-foot zones. The MLA Board purchased one of these maps to post at the lake landing and feature in upcoming communications.

• Community Investment: While some Minnesota lakes are pushing for outright bans, the MLA believes education is the best tool to protect water quality while keeping the lake enjoyable for everyone.
