Space available on Discovery Boat

Education July 14, 2017 No Response

There are still spaces available on our 2017 Discovery Boat cruises. Most, but not all, remaining spaces are in late July or early August. Please use our online reservation system to select a date and reserve space for you or your group now at

The Discovery Boat Program provides a hands-on educational opportunity for anyone to join Rob Karner, watershed biologist, and his assistants Laura Wiesen and Joe Blondia to come aboard a 22-foot pontoon boat on Glen Lake.

During the two-hour cruise on Glen Lake, you’ll discover many of the secrets of how and why Glen Lake is so unique and pristine. Many say Glen Lake is one of the most beautiful inland lakes in the country and we will explore the many reasons why.

The curriculum varies each week and is tailored to the interests of the participants of each session. Topics range from discovering how the glaciers form the lake and surrounding hillsides, wetlands, and streams to the chemistry of the water to how to prevent getting Swimmer’s Itch and GLA’s work to control it.

Testing for phosphorous in water samples

Education June 20, 2017 No Response

Phosphorous, along with nitrogen, is an essential nutrient for plants and animals. As a major component in most fertilizers, runoff or erosion can lead to too much phosphorous in the water, and the depletion of oxygen from excessive aquatic growth. Called eutrophication, it can result in animal die-off , toxins and foul water. Therefore the monitoring of phosphate levels in water is extremely important.
The Glen Lake Association collects water samples every spring and fall and sends them to Lansing where they are tested for phosphorous levels which are then compared with other lakes in the State of Michigan. This provides the GLA with valuable and comparable data for our water quality monitoring program.
