New York

Located in the Northeastern United States, New York is the seventh-most densely populated state in the U.S. The state covers 54,555 square miles and ranks as the 27th largest state by size. The Great Appalachian Valley dominates eastern New York and contains the Lake Champlain Valley as its northern half and the Hudson Valley as its southern half. Much of New York State borders water.

Estimating Loading Above and Below Agricultural Best Management Practices (BMPs) and Combined Animal Feeding Operations (CAFOs) in the Genesee River Watershed

The current information available for the Genesee River and watershed is insufficient to assess if the Beneficial Use Impairment (BUI) delisting criteria for the Rochester Embayment Area of Concern (AOC) can or have been met. With on-going and future projects that are implementing best practices to control soil erosion and the reduction of nutrients that reach the Rochester Embayment, the...

Detailed Aquifer Mapping in Wayne County, New York, The Fairport-Lyons Channel Aquifer

Introduction Detailed mapping of the glacial aquifer within the buried Fairport-Lyons bedrock channel in southern Wayne County, N.Y. is the latest study in the cooperative Detailed Aquifer Mapping Program between the U.S. Geological Survey (USGS) and the New York State Department of Environmental Conservation (NYSDEC). The aim of the program is to map the extent of glacial aquifers in New Yo...

Use of telemetry to assess potential effects of Schoharie Reservoir waters on trout populations in the Upper Esopus Creek

Background - Turbid waters originating in the Schoharie Reservoir allegedly impair habitat and resident trout populations in Upper Esopus Creek; however, to date no scientific studies have documented adverse affects of altered thermal, suspended sediment (turbidity), and flow regimes on survival, growth, or behavior of trout or the health of their populations. The 424 mi2 Esopus Creek...

National Water Quality Assessment Program -- Water-Quality Assessments of Principal Aquifers

A major focus of the NAWQA Program in its second decade (2002-2013) is on regional- and national-scale assessments of groundwater-quality status and trends in principal aquifers. The U.S. Geological Survey Office of Groundwater has identified 62 principal aquifers in the U.S. (U.S. Geological Survey, 2003). About 1/3 of the Nation's principal aquifers are the focus of water-quality assessments...

Quantitative assessment of water quality in the Upper Esopus Creek using fatty acid content of periphyton

Problem - The Esopus Creek is located in the Catskill Mountains of New York State and is part of the New York City (NYC) drinking water supply system. The basin was dammed in 1915 to form the Ashokan Reservoir splitting the creek into Upper (upstream of the reservoir) and Lower segments. The Schoharie Reservoir, located 27 miles north of the Ashokan Reservoir, supplies water to Upper Esopus...

Evaluation of a barrier-island breach created by Hurricane Sandy at Fire Island National Seashore, N.Y.

Hurricane Sandy has created three open breaches in the barrier island system along the south shore of Long Island, N.Y. In response, the National Park Service has sought assistance from the U.S. Geological Survey (USGS) New York Water Science Center (NYWSC) to help evaluate the open breach condition in Federal Wilderness near the Old Inlet area of Fire Island National Seashore, N.Y. The NYWSC...

Didymosphenia geminata in the Upper Esopus Creek: Seasonal changes in density and distribution, controlling environmental factors, and potential ecosystem impacts

Background The invasive diatom Didymosphenia geminata (didymo) has historically been a wide-spread, but rare, micro algae found in moderately flowing cold-water streams of North America, Europe, Asia, and (more recently) New Zealand. Demographic patterns of didymo have recently changed resulting in greater spatial coverage and temporal persistence (e.g. blooms) in streams worldwide. Didymo...

Effects of recreational flow releases on natural resources of the Indian and Hudson Rivers

The New York State Department of Environmental Conservation (NYSDEC) is developing a unit management plan/environmental impact statement (UMP/EIS) for the Hudson Gorge Primitive Area, an area of Forest Preserve land encompassing a scenic stretch of the Hudson River in the Adirondack Park. Two goals of the UMP/EIS are to inventory natural resources and ecosystems and take actions to protect...

Delineation of the Freshwater-Saltwater Interface at Selected Public-Supply Wells Using Advanced Surface and Borehole Geophysical Techniques, in Eastern Suffolk County, New York

The combination of a complex hydrogeologic framework, narrow land masses surrounded by saltwater, and extensive ground-water public-supply pumpage has produced localized areas of elevated chloride concentrations in ground water. This project uses advanced surface and borehole geophysical methods to determine the extent of saltwater intrusion and road-salt plumes at selected sites in eastern...

Delineation of Groundwater Flow, Lithology, Faults, and Fractures Along Existing and Proposed Water Tunnel

Problem The New York City Department of Environmental Protection (NYCDEP) has asked the U.S. Geological Survey (USGS) to assist in two major studies: 1) delineation of the source(s) of shallow groundwater and the extent that the Delaware Aqueduct is contributing to local flooding issues, and 2) delineation of the structural, geologic, and hydrologic conditions along proposed tunnel...

Using Advanced Borehole Geophysical Methods to Characterize Fractures, Foliation, and Fractured-Rock Groundwater Flow at a Geothermal Test Site on Roosevelt Island, New York County, New York

Background The U.S. Geological Survey (USGS) has characterized fractures, foliation, and fractured-rock groundwater flow penetrated by test boreholes in crystalline bedrock underlying Manhattan Island, New York County, New York since 1998. New test boreholes will be drilled on Roosevelt Island in New York County for a Cornell University geothermal test project. Cornell University is...

Identifying Thermal Refuges in the Schoharie Watershed

Problem Water temperature is a critical component of trout habitat. Stream temperatures not only affect the distribution, behavior, and survival of trout (and other species), but also compel these species to move toward small areas of preferred temperatures, known as refuges, to maximize growth, survival, and fitness. The Schoharie watershed in the Catskill Mountains, including East Kill, West...

Deepwater Cisco Stocking Off the USGS Research Vessel KAHO

The USGS Tunison Lab of Aquatic Science (Cortland, NY) and the USGS Lake Ontario Biological Station (Oswego, NY), which are both part of the USGS Great Lakes Science Center, collaborated each year from 2012-2014 in the release of deepwater cisco ("bloater") off of the USGS research vessel KAHO in the Lake Ontario waters off of Oswego, New York, in late fall.
