Caution Boaters

A yellow, containment boom has been installed to help with lake management at Lake Welch. The purpose of the boom is to prevent the migration of potential lake algae blooms from encroaching on the waterfront, swimming, and beach access areas. The boom is clearly marked with buoys and signs. Please use caution.

Attention Lake Sebago Users

Hydrilla, a federally listed aquatic invasive species, was found in Lake Sebago in late 2022. If left unmanaged this aquatic plant can severely impact water quality and recreation. State Parks is implementing a 5-year treatment plan starting early June 2023. Yellow notice signs will be placed at public access points. For more information, please visit the project website and the project brochure 

Harriman State Park, located in Rockland and Orange counties, is the second-largest park in the parks system, with 31 lakes and reservoirs, 200 miles of hiking trails, two beaches, two public camping areas, a network of group camps, miles of streams and scenic roads, and scores of wildlife species, vistas and vantage points. Harriman State Park's major facilities include Lakes Welch, Sebago, Tiorati and Silvermine, the Anthony Wayne Recreation Area, Sebago Cabins and Beaver Pond Campgrounds.

Group Camps:

Beginning in 1913, the Palisades Interstate Parks Commission built dozens of group camps throughout Harriman State Park to welcome the urban poor and provide them with hot meals and outdoor experiences. The Harriman Group Camps are the model upon which many group camping programs and sites throughout the world are based. The facilities at the camps, which are nestled in the woods next to the many lakes at Harriman State Park, consist of dining halls and recreation buildings, cabins and tent platforms, and waterfront facilities. Nature Centers offer environmental education programs designed to teach campers about the woods and instill in them a lifelong sense of wonder for the natural sciences.

For generations, the group camps have provided children and families with their first outdoor experiences. The camps are operated by a wide variety of organizations, from outdoor recreation clubs to not-for profits servicing homeless children and the disabled, from the surrounding New York and New Jersey area. The organizations are members of the Palisades Camping Association (PCA).

The Iona Island/Doodletown BCA is located within the Bear Mountain and Harriman State Parks. The area includes one of the largest tidal wetlands in the Hudson River. The ecological importance of Iona Island has been recognized through designation as: Hudson River National Estuarine Research Reserve, Significant Coastal Fish and Wildlife Habitat Area, and National Natural Landmark. The Iona Island area is an approximately 270 acre tidal wetland that ranges from freshwater to brackish. It is dominated by narrow leaved cattail. Non-vegetated tidal flats, sub-tidal aquatic beds, and rocky uplands also occur. Tidal creek channels and a high gradient freshwater creek are also present. The Doodletown portion is largely a steep, rocky, undeveloped forest land that hosts a wide array of forest-nesting species, including rare warblers. The area as a whole provides highly valuable habitats for: marsh- nesting birds, waterfowl, warblers, shorebirds, eagles, amphibians, reptiles and fish spawning and nursery areas.

Listed species include Bald Eagle (threatened), Least Bittern (threatened), Cerulean Warbler (special concern), Golden-winged Warbler (special concern), Osprey (special concern), Northern Harrier (threatened) and Pied-billed Grebe (threatened). Other bird species using the Doodletown area include Hooded Warbler, Kentucky Warbler, Louisiana Waterthrush, and Acadian Flycatcher.
