Join the Conestoga River Club for our annual Earth Day Clean up on April 25, 2026

No, seriously, tramping around along the river, pulling tires, removing trash, and taking care of the place we live with neighbors is one of the coolest things ever. Let’s rally for the river! Join us at Lancaster County Central Park Pavillion 1 at 9 a.m. to enjoy community, snacks, and coffee as we hear from speakers before heading out to our Conestoga Cleanup sites. The Conestoga has been named the 2026 Pennsylvania River of the Year, and we couldn’t think of a better way to celebrate than by stewarding this community treasure as a part of the 10th Anniversary of Water Week!
