USGS Water Science Centers are located in each state.
United States Geological Survey (USGS): Water Resources of New York
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 Bill Coon, 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.
Groundwater Sustainability of the Long Island Aquifer System
Exploratory well drilling on Long Island has begun, and is planned to continue through the summer. The drilling will better define the aquifer system, track saltwater encroachment, and inform a new groundwater-flow model for the Island. Knowledge of the effects of land use and water use on groundwater resources is critical for understanding the sustainability of Long Islandís sole source aquifer system. Read more...
