Download our Toolkit for Watershed Groups to help run/organize your local river group. There are many reasons to organize or get involved in a river group. Some citizens organize to protect their stream from an imminent threat-a dam, dredging, or clear-cutting of trees along its corridor. Others organize because they perceive a future threat to their stream or the creatures that depend on it. Many get involved just because they want to contribute to their community and to the quality of life of future generations.
