New York's abundant rivers, streams, lakes and coastal waters are used for recreation, fishing, tourism, agriculture and manufacturing. Dams and other infrastructure help us manage our waters.

Though plentiful, the water resources of the state are threatened by chemical contaminants and other pollutants from a wide range of sources.

The Division of Water provides various programs that track the quality of the waters, identify and investigate sources of pollution, control these sources and develop strategies to address water quality threats. DEC programs regulate and provide guidance on water supply withdrawal. DEC also manages floodplains and coastal areas to reduce flood risk to protect New Yorkers from coastal and inland flooding.

Water Quality Improvement Projects, Nonpoint Source Planning Grant, and Engineering Planning Grants Awarded

Governor Andrew M. Cuomo, as part of the Regional Economic Development Council Awards, announced $93 million for 85 Water Quality Improvement Project (WQIP) grants that will improve water quality, reduce polluted runoff and restore waterbodies and aquatic habitats.

WQIP grants fund projects including municipal wastewater treatment, non-agricultural nonpoint source abatement, land acquisition for source water protection, salt storage, aquatic habitat restoration, and municipal separate storm sewer systems. A full list of awarded WQIP projects is available on DEC's WQIP web page.

Governor Cuomo announced $988,636 for 36 Non-Agricultural Nonpoint Source Planning Grant (NPG) projects to produce planning reports. The goal of the program is to get nonpoint source water quality improvement projects ready for construction and to use the planning report to seek funding through WQIP or other funding entities.

Planning projects funded through NPG include in-waterbody controls for nutrients, green infrastructure, culvert repair and replacement, decentralized wastewater treatment facilities, nature-based shoreline projects, and streambank stabilization. A full list of awarded NPG projects is available on DEC's NPG webpage.


Governor Cuomo announced $3 million for 80 Wastewater Infrastructure Engineering Planning Grant (EPG) projects for the initial planning of eligible Clean Water State Revolving Funding water quality projects.

EPG provides funding to municipalities for engineering and/or consultant fees for engineering and planning services to produce an engineering report. A full list of EPG projects is available on the Environmental Facilities Corporation's EPG webpage (leaves DEC website).

DEC Encourages New Yorkers to Complete Survey on St. Lawrence River Watershed to Help Guide Revitalization Plan for Region

St. Lawrence River Watershed Project partners, including DEC, have released a survey seeking input from New Yorkers with knowledge of the watershed. The short online survey (leaves DEC website) seeks information from the public about interactions with these land and water resources, and how a revitalization plan can address regional concerns. The survey will be open until January 15, 2020.

Survey results will help guide St. Lawrence River Watershed Project partners in the development of a revitalization plan. The watershed planning process gives communities in the area a chance to consider projects that could spark natural resource protection, economic investment, regional sustainability, and community revitalization.

Governor Cuomo Announces $16.2 Million Awarded to Support Water Quality Conservation Projects

Governor Andrew M. Cuomo announced (leaves DEC website) that $16.2 million has been awarded to support agricultural water quality conservation projects across the state. More than 90 farms will benefit from the Agricultural Nonpoint Source Abatement and Control program, which provides funding to address water quality challenges in priority watersheds - such as the Finger Lakes and Susquehanna River watersheds - and protects the environment. This year, the program celebrates its 25th year of providing critical funding to support New York's farms in safeguarding the State's natural resources.

Five Star and Urban Water Restoration Grant Program 2020 Request for Proposals

The National Fish and Wildlife Foundation (NFWF) and the Wildlife Habitat Council are soliciting applications for the 2020 Five Star and Urban Water Restoration Program.

Division of Water Mission

The Mission of the Division of Water is to protect and conserve the water resources of New York State. This mission is accomplished through a wide range of programs and activities. Some of these are statewide in their scope and apply to all parts of the state. Other efforts are targeted to address water quality and quantity issues in specific regions of the state, focusing on waterbodies or watersheds where these issues are of particular concern. Still other programs target specific contaminants (e.g., mercury) or sources (e.g., stormwater runoff) or impacts (e.g., acid rain) of pollution.
