Welcome to Green River Reservoir State Park. Green River Reservoir became a state park in March 1999 when 5110 acres were purchased from the Morrisville Water and Light Department. This is not your typical Vermont State Park Green River Reservoir provides camping and paddling experiences in a remote setting.. All campsites can only be reached by paddling to them - some a 1 to 2-mile paddle from the launch site. The park will remain in its wild and undeveloped condition, with low-impact, compatible recreational use allowed on and around the Reservoir. Management activities will be only those necessary to maintain the propertys character, protect the environment and critical resources, demonstrate sustainable forest and wildlife management, control excessive recreational use, and ensure high-quality outdoor experiences for visitors. The 653-acre Reservoir includes about 19 miles of shoreline, one of the longest stretches of undeveloped shorelines in Vermont. Access to the park is in the southern part of the Reservoir off of Green River Dam Road. The Reservoir is designated as a quiet lake under Vermont Use of Public Waters Rules. Boats powered by electric motors up to 5 mph and human-powered watercraft (canoes, kayaks, etc.) are allowed.
