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 of 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.
