WTNY describes the stream flows in each of NYS 17 watersheds, including direction/path of flow, listing 1200 monitoring stations in order from headwaters to outlet, including a flow rating (where available), flow volume in cubic feet per second (CFS), the depth of flow in feet and inches, the water temperature and specific conductance (where these sensors are available). WTNY logs a snapshot of the stream flows through the state’s rivers and tributaries once a month, as per USGS Waterwatch current streamflow monitoring stations.

Rivers, creeks flowing much above normal or high (in the top 10% of flow volume recorded for that system) are shown in boldface;

flows that have breached action stage appear in red,

flows in flood stage appear in boldface red type.

Ice-affected flows are shown in italics.

Flow volume can change rapidly during snowmelt and rain events. All readings are posted as they appear as of our monthly update.

During melting and rain events, check your local upstream station flow levels at the USGS WaterWatch Current Streamflow site or sign up for high flow alerts. Streamflow data is subject to review as sensors at the monitoring stations do malfunction from time to time. See USGS Provisional Data Statement at the end of this report for more information.

To EPA Impaired Water Bodies 303d List

The EPA requires all states update a draft list of impaired water bodies (the 303d list) every two years; providing a period for public comments, presenting the draft list to the EPA. The final 303d list is published as approved by the EPA, roughly every two years.

Impaired water bodies are defined as those with contaminants measured above threshold levels, as set by the EPA Clean Water Act, or where the desired use is impaired. The latest Draft List for New York State, covering 2020-2022 has closed for public comments, being submitted to EPA for review. (See the 2020-2022 Draft Impaired Water Bodies 303(d) List, organized by watershed area, here on this site.) The 2020-2022 Draft list includes NYS lakes, creeks, rivers and reservoirs that New York Department of Environmental Conservation has recommended for de-listing, along with water bodies requiring Total Maximum Daily Load (TMDL) plans. The TMDL plan is a type of Clean Water Plans, established by a collaboration of municipal, industrial and environmental groups in an overlay zoning district.

To Hazardous Algae Blooms (HABs) Beach Alerts

Hazardous algae blooms are reported here as they are confirmed across the state, as found on the NYS Department of Environmental Conservation NYHABs notification site.

active blooms are reports current within two weeks, observed reported and confirmed. These are listed by water body with date and time of the report, placed in the applicable watershed, with location information (accuracy of our location description is limited by the accuracy of the location tag in the report to NY DEC).

Contact parks management for the current information on local conditions before heading out and consider using an on-site rapid test for microcystin toxin.

To Spills

NYS Spill Hotline: 1-800-457-7362
National Response Center: 1-800-424-8802

Reporting from the latest records uploaded to the NYS Hazardous Spill Incidents database by County each week.

Spills of petroleum products of 40 gallons or more are listed weekly in the watershed in which they occur, citing location of the spill, the contaminant spilled (if known), the quantity (if known) and the resource affected (if known) surface water, groundwater, sewer, etc, and any amounts recovered at the site.

Spills over 100 gal, very toxic chemical spills and spills that impact state waters are flagged and followed up with the spiller, the state and/or EPA authorities for more information, these are marked with asterisk.*

See NY Spills Tracker for more information on these spills as it becomes available.

Note: DEC receives upward of sixteen thousand spill reports each year; each report is investigated by qualified personnel. Report files are closed when it is determined the spill is contained and under the control of the spiller or state authorities and a clean-up plan is in place or completed.

Impaired Water Bodies (80)

80 distinct water bodies appear on the new Draft list in the Lower Hudson River Watershed.
