Get Involved


Please write to us about the ways you would like to get involved. We have several areas for you to consider (see below), but don’t hesitate to suggest your own idea/s.

Volunteers help us with:

  • Boat Washes to raise the awareness of Invasive Species and how to keep from spreading them.
  • Routine Water Quality Monitoring to check levels and to stay within sound parameters.
  • Surveys for Invasive Species spread through regular surveying of the area.
  • Revetment work on inlets and outlets.
  • Fund Raisers to pay for scientific surveys to keep us on top of our Lake’s Health issues.
  • Information Distribution to raise awareness using a variety of methods.



We graciously accept all contributions:

  • Time in helping us with various initiatives to combat invasive species, etc.
  • Information adding to our overall effectiveness
  • Monetary or other resources such as equipment/tools or property access.
  • Inform others (we can help you with necessary information or share our website with them)

Our Lake


“Many words come to mind to describe Mullett Lake: immense, fantastic, deep, enchanting, beautiful, vibrant, and diverse.”

–Excerpt from Tip of the Mitt Watershed Council 2009 Report 

Key Features:

  • MLandWatershed4th largest of 5 ‘Giant’ Lakes in Northern Michigan
  • 17,000+ acres of surface area
  • Depth of 144 feet
  • 1000+ homes on its shoreline
  • Approximately 39 species of fish (according to 2017 Survey)
  • This lake is a massive ecosystem that requires balancing nature with human enjoyment

That is where the Mullett Lake Area Preservation Society (MAPS) plays a role along with a number of other agencies who assist us in translating the science of water quality and shoreline integrity into sensible application by property owners.

An ecosystem of this size is NOT an island. It requires monitoring of the interaction between tributaries and rivers that Mullett Lake flows into: Cheboygan River, Pigeon River, to name a few.




Our Challenges

Invasive Species

  • Are species of plants or animals that are non-native to the area
  • Their introduction is likely to cause economic or environmental harm or harm to human health


Shoreline Alterations


Shoreline Erosion

Online Soil Erosion Assessment Tool

Stormwater Runoff


Boating Safety


Our Initiatives

MAPS Implements Best Practices and Brings the Science to Our Lake

Clean Boats Clean Waters

MAPS works with other organizations in the Mullett Lake Watershed to provide Boat Washes and education



MI Natural Shoreline Partnership


MI Shoreline Stewards


The Michigan Shoreland Stewards Program provides recognition for lakefront property owners who are protecting inland lakes through best management practices on their property.

Water Quality Monitoring

MonitoringTeam3 forms of measurement:

  1. PH Balance – State Law mandates between 6.5-9.
  2. Dissolved Oxygen – State Law mandates 5-7 parts per million
  3. Conductivity – indicator of water pollution

From the Mullett Lake Shoreline Survey of 2008 conducted by Tip of the Mitt Watershed Council:

“Data collected during the shoreline survey indicate that human activity along the shoreline of Mullett Lake is negatively impacting the lake ecosystem and water quality.”
