Hudson River Environmental Conditions Observing System

The Hudson River Environmental Conditions Observing System (HRECOS) is a robust environmental monitoring network operated and managed by a consortium of governmental, academic, and private institutions with shared interest in high-frequency monitoring in the Hudson River watershed. 

HRECOS monitoring stations are geographically distributed along the Hudson and Mohawk Rivers, and are equipped with sensors that continuously record a suite of water quality and weather parameters every 15 minutes, with most stations operating year-round. Remote telemetry at each station transmits real-time data for the public to freely view and download using an easily-accessible interface at hrecos.org. 

HRECOS works to improve the capacity of regional river and estuary stakeholders to: understand the ecosystem and manage water resources, provide baseline monitoring data necessary for applied research and modeling, support the use of real-time data in educational settings, provide policy makers and emergency managers with data products to guide decision making, and provide information for safe and efficient commercial use and recreational activities.
