    Water Resources of New York

    Welcome to the U.S. Geological Survey (USGS) Web page for the 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 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.

    Important -- New York Streamgages (Revised 12/11/2009)

    Click this link to see a table of sites that have been or will be shut down if funding partners cannot be found.

    Most recently we have had to shut down the gage on the Hudson River at Hastings-on-Hudson, this is a critical gage that provides information on the location of the saltwater freshwater boundary in the river as well as tide elevation and timing data for the lower part of the Hudson River Estuary. Another critical Hudson River gage located at West Point is also slated to be discontinued this fall if funding partners cannot be found. The information from these gages are needed for tracking potential impact of saltwater on water supply intakes, for understanding spawning conditions for fish species, and for providing tide elevation data used by commercial navigators.

    Users who can contribute funding for the non-Federal share of costs to continue operation of these streamgages should contact Ward Freeman, Director of the USGS New York Water Science Center (518-285-5658 or wfreeman@usgs.gov).

    New York Water Quality Network

    New York Water Quality Network

    The New York District of the U.S. Geological Survey operates a water quality network throughout the New York City Watershed funded by New York City Department of Environmental Protection. The purpose of the network is to provide surface water stream flow and water quality data for selected streams throughout the Catskill Mountains within the New York City Watershed.....Find out more

    What's in that Water? USGS Releases First Nationwide Look At Pharmaceuticals, Hormones And Other Organic Contaminants In U.S. Streams

    What's in that Water? USGS Releases First Nationwide Look At Pharmaceuticals, Hormones And Other Organic Contaminants In U.S. Streams

    Research is documenting with increasing frequency that many chemical and microbial constituents that have not historically been considered as contaminants are present in the environment on a global scale. These "emerging contaminants" are commonly derived from municipal, agricultural, and industrial wastewater sources and pathways....Find out more

    Streamstats for New York

    Streamstats for New York

    StreamStats for New York can be used to estimate instantaneous flood discharges with exceedance probabilities of 0.8, 0.667, 0.5, 0.2, 0.1, 0.04, 0.02, 0.01, 0.005, and 0.002 for ungaged, unregulated, rural streams. These exceedance probabilities correspond to recurrence intervals of 1.25-, 1.5-, 2-, 5-, 10-, 25-, 50-, 100-, and 500-years, respectively....Find out more

    Water Resources and Natural Gas Production from the Marcellus Shale

    Marcellus shale

    The Marcellus Shale is a sedimentary rock formation deposited over 350 million years ago in a shallow inland sea located in the eastern United States where the present-day Appalachian Mountains now stand (de Witt and others, 1993). This shale contains significant quantities of natural gas. New developments in drilling technology, along with higher wellhead prices, have made the Marcellus Shale an important natural gas resource.

    The Marcellus Shale extends from southern New York across Pennsylvania, and into western Maryland, West Virginia, and eastern Ohio (fig. 1). The production of commercial quantities of gas from this shale requires large volumes of water to drill and hydraulically fracture the rock....Find out more

    Flood of June 26–29, 2006, Mohawk, Delaware, and Susquehanna River Basins, New York

    (Limited number of reports available upon request at 518-285-5602 or mphillip@usgs.gov).

    Flood of June 26–29, 2006, Mohawk, Delaware, and Susquehanna River Basins, New York

    A stalled frontal system caused tropical moisture to be funneled northward into New York, causing severe flooding in the Mohawk, Delaware, and Susquehanna River basins during June 26–29, 2006. Rainfall totals for this multi-day event ranged from 2 to 3 inches to greater than 13 inches in southern New York. The storm and flooding claimed four lives in New York, destroyed or damaged thousands of homes and businesses, and closed hundreds of roads and highways. Thousands of people evacuated their homes ....Find out more
