Green River Reservoir became a state park in March 1999 when 5,503 acres were bought from the Morrisville Water and Light Department. It is remote and largely undeveloped, offering camping and paddling in a quiet natural setting. All campsites can be reached only by boat, and some are a 1 to 2 mile paddle from the access. Season runs from the third weekend in May through the second Monday in October. The address is approximate.
