The Long Island Watershed Program (LIWP) collaborates with regional stakeholders across Long Island to improve water quality, restore essential habitats, protect groundwater resources, and engage the public in environmental stewardship.
This page includes information and links, where available, about DEC initiatives and our partner’s efforts to enhance the Long Island Watershed. Many of these projects and programs were initiated under the Long Island Nitrogen Action Plan (LINAP) and will continue or expand under the Long Island Watershed Program.
