Blue-Green Algae and the Value of Water Monitoring

Recent hot weather has put lakes in the news. Some, particularly those already polluted with too many nutrients, experience blooms of toxic blue-green algae that create a health concern about getting in the water. Sometimes beaches are closed. Each year there are a few reports in the state of dogs dying from drinking that water. They are dramatic reasons lakes and rivers are monitored, but not the only reasons.

The Anoka Conservation District (ACD) monitors water quality in 20 lakes and 20+ stream or river sites. Not all waters are monitored every year.This monitoring is used for:

  • Surveillance – Identifying problems early.
  • Diagnosis – Determining the cause of problems.
  • Project effectiveness – Track how efforts to improve waters are working, and adjust management to maximize returns.


ACD focuses on lake health and recreational suitability, and can highlight places where health-related monitoring is warranted. Public beaches are required to do other health-related monitoring.

During the summer months, use caution around algae blooms. Toxic blue-green algae cannot be identified just by looking at it, but algal slimes on the water are certainly a warning sign. The Minnesota Pollution Control Agency advises, "when in doubt, stay out."

There is no practical treatment to remove blue-green algae from our lakes. It is part of the natural algae community. However, we can work to reduce nutrients that fuel algae blooms. In this way we can improve overall lake recreational suitability and reduce health concerns.

The Season of Spring Erosion (and Help for Those Experiencing It)


The excitement of spring often comes with high water, ice, and waves. This spring is no exception. Owners of property on lakes and rivers are quick to take note. And sometimes, feel a bit helpless. The Anoka Conservation District offers help to those landowners. We've got technical know-how to fix the problems. We focus on approaches that are lasting, create habitat, and improve water quality. The advice is free. As a bonus, financial help in the form of grants are often available.  During the COVID-19 pandemic, our staff are most easily reached by email, however, we are also checking voice messages. For contact information see https://www.anokaswcd.org/index.php/about-us/staff-directory.html

Natural Resources Management Often Starts With a Party

Managing natural resources is mostly about engaging people.While one landowner can make a change, groups of people can make big change.If you want to gather people to a cause, you'll need a party.

At the Anoka Conservation District we have the pleasure of being invited to many such parties.Lake associations, sporting groups, and civic groups gather people to summer barbeques, fall bonfires and winter fundraisers.Ideas for natural resources management are developed.Enthusiasm spreads.Funds are raised.Trusting relationships grow.It's arguably the foundation of natural resources management.

While we at the Anoka Conservation District are wonderfully proud of our part in natural resources management, we recognize that we are just a part.Here's a big word of THANKS to all those volunteers and groups that have parties that lead to cleaner lakes, healthy forests, and abundant wildlife!

Below are photos of a few great parties in 2019.

Leaving a Legacy on the Land through Easements

Written by: Jamie Schurbon, Watershed Projects Manager

When I was young, there was a woodlot in the neighborhood where kids, including me, roamed. It was along the river, where there were frogs to be caught. We built forts. We played games. It felt like 100 acres, but in hindsight was probably just a few. That natural area was, apart from the people, a most memorable part of the neighborhood.

What's the best part of your neighborhood? Perhaps it's a woodlot on your own property. Or a wetland the provides a little privacy. Or just a few big mature trees. We get joy from living in natural surroundings big or small. When these things are lost, the neighborhood seems to sigh in disappointment (and some folks get downright upset).

Conservation easements are one tool available to landowners who want to ensure their land is kept natural for the long term, as a legacy for the community. Conservation easements pay landowners in exchange for a restriction on certain types of changes, such as clearing and building, to the land in the future. The easement runs with the land and applies to future owners.

The newest easement program available in Anoka County focuses on properties along the Rum River. Riverbank properties are critical to the scenic and recreational qualities of the river, as well as the river's ecological quality. The program pays 60% of the assessed value of the land. You set the easement boundaries. You retain ownership. The land does not become open to the public.

Easements are purchased strategically. While many lands are eligible, not all are competitive candidates. Those that score highest are parts of larger high quality natural areas and will not become "islands" within development. Easements should help retain community character and be consistent with anticipated growth.

If you are interested in having your land considered for a conservation easement, please contact Carrie Taylor at 763-434-2030 ext. 19 or This email address is being protected from spambots. You need JavaScript enabled to view it.
