Here you'll find information on New York's rivers, lakes, and estuaries. You'll also find information about groundwater, water quality, and many other topics. The USGS New York Water Science Center operates the most extensive satellite network of stream- and tide-gaging stations in the state, many of which form the backbone of flood-warning systems. The USGS provides current ("real-time") stream stage and surface-water, water-quality, and groundwater levels for over 300 sites in New York.

For emergency situations, please contact Gary Firda, Surface Water Specialist at the USGS New York Water Science Center or call our general number (518) 285-5600 and follow the directions to leave voicemail which will be immediately forwarded to a responsible party and responded to as quickly as possible.

Data collection from 197 groundwater stations, 10 surface-water stations, 1 meteorological station, and 131 water-quality stations in the five boroughs of New York and extreme western Nassau County was suspended May 1, 2013 due to elimination of the program by a funding partner.
