Mayfly Festival
Celebrate Water, Life & Community
The Mayfly Festival is an event created by the Coos Watershed Association and local partners that is designed to shed light on the connections between community, the environment, and water. This is a free, all-ages, hands-on celebration of watershed ecology and interconnectedness through activities, games, live music, science, and art.
