Gallatin Water
Science Symposium
The Gallatin Water Science Symposium was an opportunity for water resource managers and researchers to connect with the Gallatin Water Collaborative to share their work surrounding water in the Gallatin that can inform water stewardship in the Gallatin Watershed.
This inaugural event took place on February 19, 2025, at Montana State University. Resources from the event are available below.
