Happy Discovery Boat

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 the biology of the plants and animals, to the ecology of how all the parts work together and finally, how the political forces are at work within our watershed. The life cycle of swimmer’s itch and how to prevent getting it will also be covered.

Discovery Boat activities during the cruise include making visual observations, reading the water clarity measurements, analyzing chemical properties using the hydrolab, taking bottom samples of the lake with a mini-dredge, doing a plankton tow, bringing up from the lake bottom aquatic plants and animals for identification and more.
