Hydrologic Information and Data for Maine

The U.S. Geological Survey (USGS) currently operates and maintains approximately 100 data-collection sites in Maine for acquiring information about surface-water, groundwater, water-quality, and precipitation (8 of these sites provide data for reservoirs). Of the 221 sites, 150 sites are equipped with satellite telemetry, which provide real-time data via GOES (Geostationary Operational Environmenatl Satellite) satellites and downlinks, which enables the posting of data to the Web for public dissemination.
