Recap of the MN COLA/SafeWakes seminar

Posted on   -  Updated:

Our members rank “enhanced wake activities” as one of their three most pressing issues. To that end, MN COLA has been working for years on the environmental and safety challenges from recreation using enhanced wakes. Finding ways to share and protect our incredible water resources is the goal and it will require several steps.

  • One step is to raise awareness and increase the understanding of the impacts of enhanced wake activities across the boating population. MN COLA was a vocal proponent at the 2023 legislature, arguing for a mandatory boat operator’s license in Minnesota intended to improve safety on the water. Obtaining that license requires that boaters complete an education program that addresses among other things, best practices related to boating safety, AIS, and minimizing conflicts on the water. 
  • Another step is obtaining the science to underpin possible solutions. MN COLA actively supports the work done by the St. Anthony Falls Laboratory at the University of Minnesota to understand the impact of boat wakes and propellor thrust. 
  • And we believe that some form of regulation will be required to achieve the balance needed for recreation, safety, and environmental protection. Unfortunately, a statewide approach isn’t likely in the near term. In the interim, obtaining local regulations on surface water activities may be possible using the DNR petition process. In fact, it was used in 2024 by Caribou Lake in Cook County to establish surface water restrictions on enhanced wake activities.

This special seminar was designed to provide an overview of the DNR petition process.

Sara Heger, U of MN’s Onsite Sewage Treatment Program set the stage at a recent MN COLA meeting to talk about the connection between septic systems and water quality. She discussed Minnesota’s rules, as well as how a properly operated septic system functions, and what and how things can go wrong. She is the go-to person for all things septic!

Sara’s presentation can be seen HERE.

Otter Tail County’s Vacation Home Rental Ordinance

Posted on   -  Updated:

VRBOs and similar rental situations are raising some concerns among lake residents and one county has set rules and processes for managing rental properties to the benefit of all shoreland owners and users. Chris LeClair, Director of Otter Tail County’s Land and Resource department explained the new rules and led an excellent discussion of Otter Tail County’s Vacation Home Rental Ordinance. The presentation can be seen HERE.

MN COLA June 2024 Annual Meeting speakers image

What do Kathryn Hoffman (left), Dr. John Rogers (right), Jeff Forester (top), and Hilarie Sorenson (bottom) all have in common?

They are all speaking about water at the MN COLA Annual Meeting on June 18 from 9 am – 11 am CT. The meeting is guaranteed to be interesting and informative, and we hope you will attend.

Register here for the Zoom meeting.

Meeting topics and speakers:

  • Election of Directors for the MN COLA Board. Director terms are 3 years and we have several seats to fill. Note: if you have interest in joining the MN COLA Board, please contact Kevin Farum to register your interest.
  • Kathryn Hoffman, CEO of the non-profit Minnesota Center for Environmental Advocacy (MCEA), will brief us on the efforts they have underway to protect Minnesota’s public waters. MCEA’s lawyers and scientists are directly involved with environmental legislation in St. Paul and in every major legal fight to protect our water. Kathryn last joined us in December 2020 and she was very well received.
  • Jeff Forester from MN Lakes and Rivers Advocates will provide us with an update on the short 2024 Minnesota Legislative Session that ends on May 20.
  • Hilarie Sorenson is the newly appointed Water Resources Extension Educator for MN Sea Grant. She is charged with helping to address complex water quality issues through resources and programs. We offered her the opportunity to explain her new role and also to hear from you, our caring lake and river volunteers about your priorities and needs. So besides getting to know Hilarie, you can help her help us with a few polling questions during her presentation.
  • Dr. John Rodgers from Clemson University will talk to us about hydrilla, one of the most concerning AIS that has not yet reached Minnesota. He will follow the infestation spread from Florida up the east coast and now in Michigan, the impact on lakes, and what to expect. Many of you became familiar with Dr. Rodgers when starry stonewort was found in Minnesota in 2015. We are so pleased that he will spend some time with MN COLA.

As always, everyone welcome to attend, so feel free to forward this meeting information.

Inland waters need the forest!

MN COLA strongly believes in the need for keeping and reclaiming natural shorelines. This is especially important with the trend of turning part-time cabins into full-time homes. We have many resources on our website to make that case, but it is up to us, as shore owners to understand the impacts of making changes at the shoreline and to retain and/or reclaim the elements that favorably affect water quality.

With the permission of Michigan Lakes and Streams Association, we are pleased to provide a link to a terrific article that highlights the important connection between forests and lakes for strong water quality, shoreline stabilization, resistance to AIS, and a strong fishery.

The science supports keeping the forest and lakes connected!

Whose permission do you need for shoreline work?

Shoreline regulation guide: who to call for which action on your shore

We talk a lot about reclaiming natural shorelines, but you may not have a perspective on the permissions that you will need before you do the work.

This “Regulation Guide” (pictured above) was developed by Blue Thumb and it provides that perspective on approvals you need based on what you plan to do. Blue Thumb’s shoreline stabilization webpage has tabs with Planning, Design, Installation, and Maintenance considerations.

Blue Thumb is an educational program of Metro Blooms, a Minneapolis-based non-profit.

It’s AIS season. Ready, Set, Go!

Check In - Check Out - images of cover pages of boat decontamination manual and AIS identification booklet

The open water boating season is here and many of your organizations are involved with AIS inspections, inspectors, and early detection activities. Here are a couple of things you may not know about which may help.

The Lake Tahoe watercraft decontamination manual is well-organized with 91 pages of photos and great content, including nearly 30 pages of manufacturer-specific decontamination considerations.

The MAISRC AIS identification guide contains tips for identifying a number of aquatic invasive species (AIS) that are considered high-risk to Minnesota waters, as well as some common native lookalike species. You can download it for free, buy the book, or become an AIS Detector and get the book — plus tons of hands-on training!

The free Check-In, Check-Out program was designed by our friends at CD3 to educate boaters on hand cleaning different types of watercraft and trailers. Simply place the Check-In, Check-Out QR code at a visible location at your boat launch. 

Test your private well every year

Posted on

test your well every year for coliform bacteria, nitrate, arsenic, lead, and manganese

Private wells produce 20% of Minnesota’s drinking water and serve a majority of waterfront property owners in the state. If you have a private well, you should know that the Minnesota Department of Health (MDH) recommends you test for nitrates and coliform bacteria every year, especially if babies or young children are drinking your well water.

They have a webpage on private well testing that provides more details.

Regarding Per- and Polyfluoroalkyl Substances (PFAS) – Even though MDH recently reported that 22 Minnesota water systems have PFAS levels above the new federal limits, they do not recommend that every private well is tested for PFAS. If you use a private well for drinking water that is included in an existing environmental investigation near a known source of contamination, the Minnesota Pollution Control Agency (MPCA) will notify you if your well might be affected. If you still want to test your private well for PFAS and are not a part of an MPCA environmental investigation, see the Testing your private well for PFAS section.

Harmful algal blooms: “When in doubt, stay out!”

Harmful Algal Blooms

Algal blooms occur when tiny, naturally occurring plants grow rapidly in an area of water and are visible without a microscope. Not all algal blooms are toxic, but some are. Algal blooms capable of producing toxins dangerous to humans or animals are considered Harmful Algal Blooms (HABs).

MN’s Pollution Control Agency has simple advice for algae blooms: “When in doubt, STAY OUT!”

Here is some great information:
