Bathymetry of New York City’s East of Hudson Reservoirs
Background: The New York City Department of Environmental Protection (DEP) maintains an extensive network of reservoirs and aqueducts for water collection, storage, and transport; it supplies more than one billion gallons of drinking water daily to more than nine million people. The East of Hudson (EOH) network (fig. 1) includes thirteen reservoirs – Amawalk, Bog Brook, Boyd Corners, Cross River,
Determination of Sources of Water to the Tully Valley Mudboils
Background and Problem Tully Valley is part of the Onondaga Trough, which extends from the Valley Heads Moraine in the south to Onondaga Lake in the north near Syracuse, New York (fig. 1). The Onondaga Trough is filled with a complex sequence of glacial and post-glacial sediments that overlie Devonian carbonate rock and shale and Silurian shale and salt (fig.2). Mudboils, volcano-like cones o

Lake Ontario Flood Monitoring and Mapping
Problem– Lake Ontario experienced period-of-record (1918-2017) maximum monthly average water levels during May through July 2017. NOAA lake gages recorded instantaneous peaks-of record, 249.2 at Olcott, 249.1 at Rochester, and 249.0 at Oswego and St. Vincent. These high water levels along with wind-generated waves caused flooding of thousands of residences and businesses and the erosion of miles o
Detailed Aquifer Mapping of the Oneonta Area Otsego and Delaware Counties, New York
Introduction The City of Oneonta and surrounding area is the major population center in Otsego County, N.Y. and home to two colleges (SUNY Oneonta and Hartwick College). The public water supply draws on both surface-water and groundwater sources and serves 15,954 people in the City of Oneonta and parts of the surrounding Town of Oneonta (City of Oneonta, 2013). The remaining population uses domest
Long Island Topography
The present landforms of Long Island are the result of many geologic processes, some of which began many millions of years ago and some of which began only recently. Most of the major features of the present-day topography, however, are related to the last glaciation, which ended approximately 22,000 years ago.
Long Island Land Use and Land Cover
On Long Island, land use includes the human activities and management practices for which land is used. Land cover is a mosaic of developed, forest, agriculture, and wetlands areas. Both land use and land cover are usually discussed in similar environments. The National Land Cover Database (NLCD) serves as the definitive LANDSAT-based, 30-meter resolution, land cover database for the Nation. NLCD...
Long Island Water Availability
The foundation of any groundwater analysis, including those analyses whose objective is to propose and evaluate alternative management strategies, is the availability of high-quality data. Some, such as precipitation data, are generally available and relatively easy to obtain at the time of a hydrologic analysis. Other data and information, such as geologic and hydrogeologic maps, can require...
Groundwater Monitoring on Long Island, New York and the Five Boroughs of New York City
The groundwater data-collection network of the USGS New York Water Science Center, Coram Program Office encompasses data collection from approximately 600 groundwater-monitoring wells on Long Island and in the five boroughs of New York City. Data from these stations are collected in varying frequencies to supply our cooperators, stakeholders, and the public with mission critical information.
Delineation of the Saltwater-Freshwater Interface at Selected Well Locations in the Town of Riverhead, NY
Problem The Town of Riverhead in the northeastern Suffolk County includes rural farmland and suburbs and is bounded by the Long Island Sound to the north and Peconic Bay to the southeast. Riverhead’s close proximity to saline embayments and its location along the northeastern discharge area for Long Island’s groundwater flow system makes it vulnerable to saltwater intrusion. Several public-suppl
