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.

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...

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...

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...

Esopus Sub Basin Sediment and Turbidity Monitoring

Problem The Esopus Creek is located in the Catskill Mountains of New York State and is part of New York City’s water supply system. In 1915 damming of a portion of the creek formed the Ashokan Reservoir splitting the creek into upper (upstream of the reservoir) and lower (downstream of the reservoir) segments. The Ashokan Reservoir watershed is 255 mi2 and is one of two reservoirs in the New...

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...

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...

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...

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...

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...

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...

Adirondack Long-Term Stream and Soil Monitoring

The current Adirondack Long-Term Monitoring Program combines monitoring of streams and soils based on a watershed design. Not only are headwater streams an important component of Adirondack ecosystems, they are closely tied to the terrestrial environment through runoff that is strongly influenced by soil and vegetation processes. This linkage makes headwater streams a useful tool for monitor...

Effects of flow alteration on ecological health of streams across the Atlantic Highlands Ecoregion

Problem: The Clean Water Act (PL 92-500) requires that the health of the Nation’s rivers and streams be assessed on a regular basis, and in the Northeast such assessments often use information from aquatic biological communities that live in the stream. Biomonitoring programs implemented by individual states evaluate biological data to assess stream health on the premise that certain...
