Find information on the river flows in your watershed each week. WTNY logs a snapshot of the volume of water flowing through the state’s rivers and tributaries, as per USGS streamflow monitoring stations. The report captures your watershed flows from headwaters to outlet as of the date indicated.
Systems reporting much above normal or high flows (in the top 10% of flow volume for that system) are shown in boldface; Flows in action stage or flood stage appear in red. Ice affected flows in italics.
Flows can change rapidly, check your local upstream stations at the USGS WaterWatch Current Streamflow for real-time updates. Data is subject to review, errors occur from time to time, see USGS Provisional Data Statement.
2020-2022 Draft Impaired Water Bodies 303(d) List (see the full list on this site) The NYS lakes, creeks, rivers, and reservoirs that have been recommended for de-listing, or those requiring Total Maximum Daily Load (TMDL) plans, a collaboration of municipal, industrial and environmental groups working together in an overlay zoning district for the specific purpose of addressing water quality. EPA Clean Water Act requires action where water quality tests indicate stress: excess nutrients, contaminants, or low oxygen. The period for public comments on the draft 2020-2022 list is now closed.
Hazardous materials spills reported to NYS Spills Database are included in the relevant in watershed section each week. The spill records are received and stored by County. WT reports these spills by watershed area.
WaterToday New York gathers source information and data from EPA, USGS, NWS, NOAA sources; accuracy is dependent on these sources. Provisional data statements apply, confirm data with local sources before taking action based on these reports.

Water quality parameters are detected at certain sites, including temperature (°C) and specific conductance (µS/cm). Specific conductance is an important measurement for water quality. This is a measure of the way that electrical current moves through the water; any change in this number is an early warning of changing contaminant loads. The measurement taken by USGS is temperature adjusted to 25°C, allowing for comparison of the specific value from week to week.
