May 31 webinar – Update on wakes, waves, and propeller wash research from UMN’s SAFL

May 31, 2023 @ 6:30 pm - 8:00 pm

Register today for this webinar with Jeff Marr and Andy Riesgraf of the St. Anthony Falls Laboratory, University of Minnesota for an update on this critically important research: recently completed, in-process, and future.

This free session is on May 31 from 6:30 pm to 8:00 pm, but you must register in advance. Big thanks go to Minnesota Lakes and Rivers Advocates for hosting the session.

Jeff Forester, Executive Director of Minnesota Lakes and Rivers Advocates said this about the upcoming webinar:

“Boating season is upon us. Minnesotans, as they have for generations, will enjoy sun and water and fun. But there the similarity ends. Many of the new boats on the water bear no resemblance to your grandfathers fishing boat.

The boats now are larger and far more powerful. Where once boats were powered with 25 HP or maybe 50 HP motors and 40 knots was considered fast, there are boats on the market now that go over 70 mph or have engines generating 400 hp or more. And there are more of them.

It is time to try to see what the impacts of our boats, wakes, prop thrust and boating habits are on lake ecology and wildlife. Minnesota Lakes and Rivers has been working the last few years to support funding for world class researchers to begin exploring these issues.

We wanted to provide an opportunity for you to learn more. 

This presentation by Jeff Marr will summarize completed comparative research on the size, energy, and power of boat-generated wake waves produced by a number of recreational boats under various modes of operation and data-informed guidance on recommend operational distances for enhanced wake watercraft.

The presentation will also share an update of ongoing research focusing on characterizing the propeller wash created by recreational boats and potential implications of propeller wash on lake health.

Finally, Jeff Marr will present our research plans for an upcoming research study, pending funding by the State of Minnesota, that will explore environmental impacts of boat-generated wave, propeller wash and wind driven waves.

The presentation will allow time for questions and discussion.

We hope to see you there and enjoy the spring.
