Long Island Watershed Program
The Long Island Watershed Program (LIWP) is a New York State Department of Environmental Conservation (DEC) program to guide water quality related activities happening in and around the Long Island watershed. Long Island’s water resources are vital to the residents, countless tourists, and the aquatic and terrestrial species that inhabit the island. The LIWP is guided by the LIWP Action Agenda, a 10-year strategic plan focusing on water quality and that which is impacted by it.
Water Quantity Management
DEC’s Division of Water plays a role in water conservation throughout the state through drought management, water withdrawal permits, and more. Long Island has a specific water quantity program, the Long Island Well Program, to protect and conserve water supplies.

DEC’s Division of Marine Resources has the responsibility of conserving marine habitats and resources, as well as managing recreational fishing. More information can be found on the webpages below.
