The Green Bay Chapter of Trout Unlimited (GBTU) is an all-volunteer conservation nonprofit working to care for and recover rivers and streams and the trout that call them home. Working with TU staff and community partners, we bring people together to make our trout and salmon fisheries stronger, our water cleaner, and our communities healthier. Join us and be a champion for your rivers and streams.
If you have the interest and time to make a deeper commitment to our local conservation and education work, we’d welcome you on the board or one of our many committees. To get started, connect with a GBTU board member at one of our monthly gatherings or upcoming events, or contact us to learn more.
