Please join us at our 2019 Watershed Butterfly Festival, the Watershed’s largest annual educational event that focuses on the importance of maintaining a balance between humans and the natural world. This family-oriented day has grown to be a major regional event, attracting more than 3,000 visitors.  We welcome visitors every summer to tour the Kate Gorrie Butterfly house, explore the insect zoo, meet butterfly stilt walkers, take farm tours and other fun activities.
