The Hudson River Environmental Conditions Observing System (HRECOS) is a network of real-time monitoring stations on the Hudson River Estuary. The stations are geographically distributed from Schodack Island to the New York/New Jersey harbor and are monitoring river conditions every 15 minutes.

You can use the Offsite Links on the right side of the page to visit the official HRECOS page for:

  • Two Day Forecasts - Reliable predictions of water level, water temperature, salinity, wind speed and direction and other parameters.
  • Current River Conditions - Real-time reporting of hydrologic and meteorologic river conditions
  • The HRECOS Classroom - Lesson plans utilizing HRECOS collected from collaborating educators.
  • HRECOS Stories - Short descriptions of river phenomena learned from the HRECOS data set and written for the general public

HRECOS is operated by a consortium of partners from government and the research community:
