The Three Arrows Cooperative Society, Inc. is the successor organization to the Barger Street Cooperative Society, chartered in 1937. Early members purchased 125 acres of farmland in Putnam Valley, NY and formed a cooperative summer colony which eventually grew to include 75 individual units. The colony, sometimes known as Camp Three Arrows, is modeled on socialist and communitarian values and offers residents a wide range of cultural, educational and leisure activities. The website contains information on property listings, news articles about the the co-op, planning meeting listings, calendar of events, activities offered, area attractions, governance, publications, and information related to the "Save the Lake" initiative to keep toxic algae growth from Barger Pond.
