Groundwater and Streamflow Information
Groundwater and Streamflow Information
Groundwater and surface water are among the Nation’s most important natural resources. The USGS provides unbiased, timely, and relevant information, studies, and data about water resources of the Nation. The NYWSC maintains a network of more than 300 surface water and 650 groundwater monitoring stations across New York State; over the years, the USGS has collected water-resources data at approximately 1.5 million sites in all 50 States, the District of Columbia, Puerto Rico, the Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands. The data collected at the various sites are synthesized in State-level, interstate, and international studies to evaluate resources not only in one State but also other States and countries that might be affected or may influence the condition of surface water and groundwater. The data collected are used in studies of water supplies, groundwater contamination, flooding, water stored in ice and the oceans, and the effects of climate and land use change and manmade influences.

Webcams - New York Water Science Center
Webcams have been installed at a number of locations in New York to allow you to view, in real time, the current river-stage conditions.
Groundwater-level Monitoring for Characterization of Hydraulic Connections in the Basal Sand & Gravel Aquifer, Hoosic River Valley, Hoosick Falls, New York
Hydrogeologic characterization of the basal sand and gravel aquifer in the Hoosic River valley in Hoosick Falls, New York is important for determination of sources, extent, and future migration of PFOA groundwater contamination; evaluation of potential remedial actions; and appraisal of alternative groundwater supplies. Variations in the current pumping stresses and a planned 72-hour aquifer t
USGS Hudson River Watershed Suspended-Sediment Monitoring Network
The USGS NY Water Science Center maintains a network of near-real-time sensors to monitor the movement of suspended sediment into and through the freshwater reach of the tidal Hudson River. Information from this network helps quantify the movement of sediment in the watershed to assist resource managers and stakeholders reduce dredging costs, target resources to mitigate soil loss, and modify land...
Assessment of stormwater control measures at the Niagara River Greenway Project, Buffalo, New York
Background The proposed study will examine any existing data from the monitoring wells, weather station, and flow through the storm sewer system (supplied by Buffalo Sewer Authority) to determine the dynamics of the system during storm events. Further analysis using all available information is needed to fully understand the relationship of events to the implementation of Green Infrastructure sto
Hydrogeology and Simulation of Groundwater Flow in Fractured Rock in the Newark Basin, Rockland County, New York
Groundwater in the Newark basin aquifer flows primarily through discrete water-bearing zones parallel to the strike and dip of bedding, whereas flow perpendicular to the strike is restricted, thereby imparting anisotropy to the groundwater flow field. The finite-element model SUTRA was used to represent bedrock structure in the aquifer by spatially varying the orientation of the hydraulic conducti
Esopus Creek Sediment and Turbidity Study
Background The Ashokan Reservoir is located in the Catskill Mountains of New York State and is part of New York City’s (NYC) water supply system. The NYC water-supply system is operated by the NYC Department of Environmental Protection (NYCDEP) under a filtration avoidance determination (FAD) issued by the New York State Department of Health. The Ashokan Reservoir watershed is 255 mi2 and is one o
Statewide Assessment of New York’s Karst Aquifers With an Inventory of Closed-Depression and Focused-Recharge Features
Background: The New York State Departments of Environmental Conservation (NYS DEC) and Health (NYS DOH) are concerned about groundwater contamination in the carbonate-bedrock aquifers in New York, especially relating to the unintended introduction of volatile organic compounds (VOCs) and liquid manure to these aquifers. These carbonate rocks form extensive aquifers that transmit, and can yield, wa
Hydrologic Climate Change Indicators
Background Streams and rivers are an important environmental resource and provide water for many human needs. Streamflow is a measure of the volume of water carried by rivers and streams. Changes in streamflow can directly influence the supply of water available for human consumption, irrigation, generating electricity, and other needs. In addition, many plants and animals depend on streamflow
Development of a Ground-Water Flow Model for the Manhasset Neck Peninsula, Nassau County, New York
Problem The ground-water flow system underlying the Manhasset Neck Peninsula, which provides potable water to the local population, consists of a complex assemblage of Pleistocene- and Cretaceous-age sediments that form five aquifers and at least two confining units. Recent hydrogeologic mapping in Manhasset Neck indicates significant glacial erosion of the Magothy aquifer, Raritan Clay, and Llo
Simulation of Zones of Groundwater Contribution to Three Well Fields Southwest Portion of the Naval Weapons Industrial Reserve Plant, Bethpage, New York
Summary The U. S. Geological Survey (USGS) will conduct simulations using existing aquifer data, including geologic logs from vertical profile borings (VPBs) and well installations, water levels, and pump test data available from the water districts for these production wells. Subsequently USGS will incorporate data from a groundwater pump test and additional data from new VPBs and monitoring w
A New Tool for Estimating Daily Mean Streamflow Statistics at Rural Streams in New York State, excluding Long Island
The lakes, rivers, and streams of New York State provide an essential water resource for the State. The information provided by time series hydrologic data is essential to understanding ways to promote healthy instream ecology and to strengthen the scientific basis for sound water management decision making in New York. The U.S. Geological Survey, in cooperation with The Nature Conservancy and the
Water Resources of Monroe County, New York
In 1979, the U.S. Geological Survey (USGS) entered into a cooperative agreement with Monroe County (MC), which, over the span of more than three decades, has resulted in more than 30 reports that have summarized flow and water-quality data at sites in Monroe County and have presented the results of investigations of particular water-related issues that existed in the County. The collaborative rela
