East Arm Rowing Club is a non-profit organization dedicated to the promotion of rowing in the Hudson Valley region. It rows out of Greenwood Lake, the largest freshwater lake in the vicinity of New York City. The boathouse is located some three miles off the Appalachian Trail and lies in a protected valley surrounded by mountains including New York's Sterling Forest State Park. The club prides itself on it's eclectic mix of nationalities and inclusive membership ranging from young to "old".

Greenwood Lake is six miles long and the club is on the protected East Arm and almost always rowable. The club has experienced rowers and good boats (recent acquisitions include two eights (primarily for the high school programs), a state of the art 4+ (through a very generous arrangement with one of our members) and a quad bought by another one of the members.) There is an excellent beginners' training program as well as a training device to accelerate development of skills. The club is fiscally sound (one of the few to own it's own boathouse) and members compete both regionally and internationally. The club sponsors a USRA accredited regatta each year on the East Arm.

East Arm is also the home of the Warwick Valley High School and the Tuxedo High School crew teams this year.
