Water Quality
Little Traverse Lake Association is keeping watch on important aspects of water quality to give us the data that we need to understand aquatic chemistry and biology. These efforts aim to keep the lake healthy for human recreation and as a natural ecosystem.

Good Harbor Bay Watershed
"The Leelanau Conservancy has partnered with Lake Associations and other organizations to help write watershed protection plans for the major watersheds in Leelanau County. These plans are a guide for watershed residents to help maintain and improve the health of their watershed."
"The Good Harbor Bay watershed plan was developed to better examine and understand the watershed and to identify ways to protect the watershed’s natural functions. The rationale for watershed management is that if land activities are responsibly managed, the water within that watershed will be protected. All activities within a watershed affect the quality of water as it percolates through and runs across natural and developed landscapes.
