Public Notice

Data Solicitation for the 2026 Integrated Report on New York State Water Quality

The New York State Department of Environmental Conservation (NYS DEC) is seeking water quality data and information for any New York State waterbody.

Water quality data and information received may be used to update waterbody assessments in the state's Clean Water Act Section 305(b) Report, https://dec.ny.gov/sites/default/files/2024-09/cleanwateractreport.pdf or the Clean Water Act Section 303(d) List of Impaired Waters, https://view.officeapps.live.com/op/view.aspx?src=https%3A%2F%2Fextapps…. Waterbody assessments are conducted following the methodology described in the Consolidated Assessment Listing Methodology (CALM), https://dec.ny.gov/sites/default/files/2024-05/calm.pdf.

On September 12, 2025, NYS DEC will be hosting a public webinar covering the Data Solicitation Submittal Process. Visit NYS DEC's website to register https://dec.ny.gov/nature/waterbodies/watersheds/management/assessment.

Data Requirements:

To be used for assessments, data must be:

  • Accompanied by a Quality Assurance Project Plan (QAPP) and a Data Usability Analysis Report (DUAR)

When to Submit Data:

To be considered for the 2024/2026 Integrated Report, data and information must be received by October 28, 2025.

Background:

Every two years, states are required by Section 303(d) of the federal Clean Water Act to compile a list of waters assessed as "impaired", meaning they do not meet water quality standards and cannot support their best uses. A Total Maximum Daily Load (TMDL) must be developed for these waterbodies to reduce pollutants and help them meet applicable water quality standards. The water quality data that NYS DEC may consider for assessments can come from a variety of sources, including but not limited to: NYS DEC monitoring programs, other state agencies, federal agencies and non-governmental entities such as watershed organizations, lake associations and academic researchers.

More information on data requirements and DEC's process for conducting assessments is described in the CALM, https://www.dec.ny.gov/chemical/31290.html.
