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.

What's New in the Division of Water?
This section is updated weekly and topics are typically posted here for about 30 days. If a topic has a specific end date (such as a public comment period or an event), the description is removed after the end date.
Round XI of Consolidated Funding Application Open
The Regional Economic Development Council's Consolidated Funding Application (CFA) opened May 10 and will be open until 4:00 PM on July 30, 2021. The Division of Water has two grant programs available in the CFA:
- Water Quality Improvement Projects (WQIP): WQIP funds implement projects to address documented water quality impairments or protect a drinking water source. Eligible project types include wastewater treatment improvement, non-agricultural nonpoint source abatement and control, land acquisition for source water protection, salt storage, aquatic connectivity restoration, and marine district habitat restoration. For full program details and requirements, including maximum award amounts, required match, and project type descriptions, view DEC's WQIP webpage.
- Non-Agricultural Nonpoint Source Planning and MS4 Mapping Grant (NPG): NPG funds production of planning reports for nonpoint source water quality improvement projects and mapping of Municipal Separate Storm Sewer Systems (MS4). For full program details and requirements, including eligible grant categories, view DEC's NPG webpage.
Funding Available to Support High Hazard Dam Repairs
DEC Commissioner Basil Seggos has announced $650,000 in grant funding is now available to assist eligible dam owners with infrastructure repair costs. Funding is provided through the Federal Emergency Management Agency's (FEMA) High Hazard Potential Dam grant program. DEC is now accepting applications for grants to assist with technical, planning, design, and other pre-construction activities associated with the rehabilitation of eligible dams classified as High Hazard dams.
The deadline for applications is June 11, 2021. The Request for Applications is available online through the NYS Grants Gateway (leaves DEC website).
DEC Extended Public Comment Period for Draft Cayuga Lake Total Maximum Daily Load (TMDL)
DEC is accepting written comments on the draft Cayuga Lake TMDL until 5 p.m. on July 8. The draft Cayuga Lake TMDL is available on DEC's Clean Water Plans webpage. A recording of a virtual presentation about the draft TMDL held on April 19 can be accessed from DEC's Cayuga Lake TMDL Outreach page. View DEC's April 7 press release and the May 12 Environmental Notice Bulletin for more details.
State Pollutant Discharge Elimination System (SPDES) Priority Ranking List 2021 Announced
DEC has announced the Environmental Benefit Permit Strategy (EBPS) priority rankings for 2021. You can find the 2021 SPDES permit lists and additional information about the EBPS process on the Division of Water's SPDES webpage.
Look for the Zero: Use Only Phosphorus-Free Lawn Fertilizer
DEC encourages homeowners to go phosphorus-free when using lawn fertilizer. Consumers should review bag labels for phosphorus content when shopping for fertilizer. Fertilizer labels have three numbers. The number in the middle is the percentage of phosphorus in the product, so a zero in the middle means the fertilizer is phosphorus free.
Regardless of the lawn's location, excess phosphorus can wash off and pollute lakes and streams, harming fish and ruining boating and swimming. More than 100 water bodies in New York State cannot be used due to phosphorus overuse. For more information, visit DEC's Lawn Fertilizer webpage.
Drinking Water Source Protection Program Newsletter
As part of New York's Drinking Water Source Protection Program (DWSP2), DEC has launched a monthly e-newsletter to provide information about a variety of subjects related to protecting New York's drinking water sources. Newsletter topics will include DWSP2 program updates, resources available, potential funding sources, implementation projects, and more. Sign up (leaves DEC website) for the DWSP2 newsletter to stay informed on this topic.
New York Harmful Algal Blooms Notification and Reporting System
When it comes to HABs, DEC encourages New Yorkers to:
- Know It - HABs vary in appearance from scattered green dots in the water, to long, linear green streaks, pea soup or spilled green paint, to blue-green or white coloration.
- Avoid It - People, pets and livestock should avoid contact with water that is discolored or has algal scums on the surface.
- Report It - The public should report a suspected HAB through the NYHABs online reporting form available on DEC's website. Report health concerns related to HABs to DOH at harmfulalgae@health.ny.gov, or contact your local health department.
Most algae blooms are harmless. However, exposure to toxins and other substances from certain HABs can make people and animals sick.
For more information about HABs, visit DEC's Harmful Algal Blooms (HABs) webpage. You can download the HABs brochure and program guide - which includes information and links to resources regarding bloom prevention, management and control - from the webpage.
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.
