Welcome to the Division of Water webpage! The Division conducts a variety of programs to protect and conserve New York's waters. On this page you will find information about the Division's programs and recent activities.

What's New in the Division of Water?

The Division of Water uses this page to highlight water-related information that we think may interest you. This page 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.

Harmful Algal Bloom Notifications

New waterbodies with harmful algal blooms (HABs) have been added September 22 to DEC's Harmful Algal Blooms Notifications webpage.

This week, 16 waterbodies were added to the notification list. There are currently 65 waterbodies with blooms on the list.

Help Prevent HABs

Everyone can help reduce the likelihood of HABs in waterbodies by helping to limit the amount of nutrients (phosphorus and nitrogen) that are added to the lake by:

  • Reducing the use of lawn fertilizers
  • Proper care of septic systems
  • Planting and maintaining shoreline buffers
  • Working with local and county governments to identify sources of nutrients and helping to develop strategies to reduce inputs

Nutrient control strategies are discussed in detail in chapters 7 and 9 in the DEC and New York Federation of Lake Associations' publication, Diet for a Small Lake.

Avoid and Report Suspected Blooms

Because waterbodies may have HABs that have not been reported to DEC, we recommend avoiding contact with floating mats, scum and discolored water.

If you suspect you have seen a HAB, or you, your family, or pet has been in contact with a HAB, please follow the instructions for reporting a bloom to DEC. If you see it, avoid it and report it!

NYS County Receives Chesapeake Bay Water Quality Grant

The National Fish and Wildlife Foundation and the U.S. Environmental Protection Agency have announced more than $12.6 million in grants to support the restoration and conservation of the Chesapeake Bay watershed, including nearly $900,000 to the Tioga County Soil and Water Conservation District in New York State to restore wetlands, rehabilitate stream reaches, install riparian buffers and implement grazing practices. These projects will improve and protect local water quality in addition to reducing the amount of nutrients and sediment making their way to the Chesapeake Bay. For more information, view the Chesapeake Bay Program's press release - a direct link is in the "Links Leaving DEC's Website" section on the right side of this page.

DEC Awards More Than $200,000 for Mohawk River Basin Program Grants

The grants, funded by the New York State Environmental Protection Fund, will help to improve water quality, promote resiliency, and create recreational opportunities for watershed communities, all goals outlined in the Mohawk River Basin Action Agenda. For more information, view DEC's September 11 press release.

National Estuaries Week is September 16-23

National Estuaries Week celebrates the many ways we benefit from healthy, thriving coastal ecosystems. For more information about New York State's five major unique estuary systems, visit DEC's Estuary Management Programs webpage.

WI/PWL Water Quality Assessment Updates

Most recently, WI/PWL Fact Sheets for the following watersheds/waterbodies have been revised/updated:

Comments on these (or other) assessments are welcome via email.

Draft Intended Use Plans Released for Federal Fiscal Year 2018

The New York State Environmental Facilities Corporation (EFC), DEC, and the Department of Health have announced the availability of the Draft Federal Fiscal Year 2018 Intended Use Plans (IUPs) for the Clean Water State Revolving Fund (CWSRF) and the Drinking Water State Revolving Fund (DWSRF). The CWSRF and DWSRF programs are available to municipalities and certain non-municipal entities in New York State to finance water quality and drinking water related projects. Each project for which CWSRF or DWSRF financing is desired must be scored, ranked, and listed on the IUPs to be considered.

Written comments on the draft IUPs will be accepted through 5:00 PM on October 10, 2017. For information on how to comment, as well as details about a scheduled public meeting and hearing, and a webinar, view the August 23 Environmental Notice Bulletin.

The Division of Water's webpages fall mainly into one of the two following locations:

  • Water Pollution Control - Information, guidance material and forms about the programs the Division of Water administers to control sources of water pollution.
  • Lands and Waters - Water resource information is divided into the following categories:
    • Watersheds, Lakes Rivers: Information on NYS watersheds and other water bodies
    • Oceans & Estuaries: NYS marine and estuary resource information
    • Groundwater: Aquifer and groundwater information & resources
    • Dam Safety, Coastal & Flood Protection: Program information related to flood protection, floodplain development, dam safety, and coastal management
    • Water Supply & Reclamation: Information on protecting New York's public water supplies and drought information

Division's 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.
