Board of Directors

Our Board of Directors is dedicated to the restoration of Johnson Creek Watershed. Through their excellent leadership, the Johnson Creek Watershed Council has been able to restore and improve habitat throughout the watershed. The board recently completed a new Strategic Plan that incorporates our dedication to an inclusive future, and they are actively involved in fundraising to make that future a reality.

We are always interested in building the capacity of our board. If you are interested in serving on the board as a volunteer or a jurisdictional representative, or if you would like to volunteer for a committee, please read more about our needs by clicking the button below.
