Become a River Guardian! We will help you.
The Thornapple River is greatly affected by the health of its tributary watersheds. If these small contributing watersheds are adopted by local groups, the continued health of the whole watershed is more likely to be preserved and restored.
The EPA lists several significant tributaries; there are many smaller ones that are not listed. They are all vitally important. If you live near or on one of these streams, consider becoming a River Guardian, and put that watershed under your personal stewardship. Please contact the TRWG and we will assist you, or direct you to an existing group.

There are several existing Lake and Dam associations within the watershed. Those groups and their contact information and activities will be posted here. Please check back later, or email if you need the information or would like to start one.
