With the Flow – New York State Watershed Report for the Week of Dec 6 - 12, 2021 – Flows are very calm this week, with some above normal in the Delaware River watershed
Find information on the river flows in your watershed each week. WTNY records one weekly measurement, taken as a snapshot of the volume of water flowing through the state’s major rivers and their tributaries, as recorded at 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. Flows can change rapidly, always check your local station at the USGS WaterWatch Current Streamflow for real time values.
Impaired Water Bodies in each watershed are listed here – these are lakes, creeks, rivers and reservoirs that have been recommended for a Clean Water Plan, a collaboration of municipal, industrial and environmental groups working together in an overlay zoning district for the specific purpose of addressing water quality. These are surface water bodies where water quality tests indicate stress: excess nutrients, contaminants, or low oxygen; these water bodies are listed on New York State 2018 Final Section 303 (d) list, along with the contaminant of concern and suspected source of contamination. The NYS DEC recommends the water body for a Total Maximum Daily Load (TMDL) watershed protection plan, and local watershed organizations, industry and municipalities are encouraged to undertake projects.
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, we report these spills in their relevant watersheds on the basis of the majority of the county flow.
WaterToday New York gathers data from EPA, USGS, NWS, NOAA sources; accuracy is dependent on these sources.

Report Key:
High Flows: WTNY reports systems with flows rated “much above normal” or “high” in boldface each week; flows in action stage or flood stage will appear in red. Data is gathered from the USGS WaterWatch real time streamflow.
Monitoring stations vary in the amount of data collected, certain stations report flow depth and flood stage only, the majority of stations included in this report show the variability of the flow, with a rating of low, normal, above normal, much above normal or high. Flows that would be in the top ten percent highest recorded for that system (above 90th percentile, much above normal, high) appear in boldface type. Flows at action stage or flood stage appear in red. 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.
National Weather Service: high water terminology here https://www.weather.gov/aprfc/terminology
Impaired Water Bodies (these are lakes, reservoirs, rivers or parts of rivers with water quality tests indicating the system is impaired; these are listed in New York State 2018 Final Section 303 (d) list, along with the contaminant of concern and suspected source of contamination. The NYS DEC recommends the water body for a Total Maximum Daily Load (TMDL) watershed protection plan.
