Introduction

To Flows

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 Waterwatch current streamflow monitoring stations. The report captures your watershed flows from headwaters to outlet as of the date indicated. 

• 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 weekly 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 Impaired Water Bodies

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, and 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 with contaminants measured above threshold levels 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 the 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 Spills

Reporting from the latest records uploaded to the NYS Hazardous Spill Incidents database by County each week. Spills are included in the relevant in watershed section, with location of the spill, the contaminant spilled (if known), the quantity (if known) and the resource affected (if known, including air, soil, impervious surface, surface water, groundwater, sewer, etc). The DEC receives over ten thousand spill reports each year; WTNY list the reports as they are reported in each County, roughly in the watersheds where they occur, to the best of our knowledge.

To HABs

Hazardous algae blooms are reported here as they are confirmed across the state, beginning in May of each year, as found on the DEC HABs notification page. These reports are listed by County, for each watershed area. Contact parks management for more information on local conditions before heading out and consider using an on-site rapid test for cyano-toxin.

Sources:

WaterToday New York aggregates information and data from the New York State Department of Environmental Conservation, Department of Health, Region 2- EPA, USGS, NWS, NOAA by watershed area. The accuracy of the information contained in our reports is dependent on these sources. Provisional data statements apply, confirm data with local authorities before taking action.

Report Key:

Flows: USGS 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. 

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.
