SEE EVENTS BELOW

Help us promote this month-long lineup by posting our CYRM Flyer.

The York River Stewardship Committee is promoting programs and activities that are free and open to the public during Celebrate York River Month to showcase the amazing resources and special places in the watershed. We’re excited to connect people to the organizations whose work helps care for the York River and to groups that want to share their knowledge and inspiration with others. Most Celebrate York River Month events are organized and led by others, and many require registration in advance and might have participation limits. 

Why September 10 to October 10? We chose a lunar cycle for our “month” since York River is a coastal river, with its tides influenced by the moon’s phase. New moons mark the start and end of our month-long celebration, and the September 26th full moon is right in the middle. 

What’s a watershed? It’s the land area from which water flows into the network of wetlands and tributaries that form a river system. The watershed for York River includes land in South Berwick, Eliot, Kittery and York.
