Volunteers are invited to participate in a day of service to the Hudson River by joining the Riverkeeper Sweep in the Village of Catskill (beginning at 8 a.m.) and city of Hudson (10 a.m. to 1 p.m.). Volunteers will pick up garbage from the shoreline at Dutchman’s Landing Park and sites on the Catskill Creek as part of this river-wide event. Henry Hudson Riverfront Park is also an organized cleanup site. Volunteers for the Catskill Sweep can participate all day, or for a portion of the day.
