New York Water Science Center

Geospatial Applications

The USGS is the Nation’s largest Earth science civilian mapping agency, mapping in the United States and abroad for more than 125 years and changing products and services offered and the means by which they are developed to meet changing expectations of users, new understandings of societal and mission needs, and new technologies. The NYWSC uses the latest available spatial datasets to provide geospatial expertise for scientific investigations; geographic information systems (GISs) are used to characterize the natural and manmade features that define the environmental settings of drainage basins and groundwater study areas. As the quality and resolution of remotely sensed geospatial data and imagery continues to improve, GISs can be used to visualize and explore these data. For example, light detection and ranging (lidar) elevation data can be displayed with hill-shade and color classifications that provide far greater detail than 1:24,000-scale topographic maps.

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...

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 cone...

Development of Long Island Water Quality Integrated Data System (LIQWIDS) - User interface and web services in support of collaboration under the Long Island Nitrogen Action Plan(LINAP)

PROBLEM There are more than 60 organizations and agencies collecting water-quality data on Long Island. The types of database management that are used to store and archive regulatory and non-regulatory data vary from paper forms to spreadsheets to State and Federal databases, and there is minimal communication between these systems. As a result, those interested in analyzing data may be...

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...

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...

Long Island State of the Aquifer System

One of the most important concepts to understand is that volumes of water pumped from a groundwater system must come from somewhere and must cause a change in the groundwater system. Another important concept is that water table aquifers are hydraulically connected to the streams that drain them. Therefore, pumping water from aquifers that are hydraulically connected with surface-water bodies...

Flood-Inundation Maps for Four Stream Reaches, Ithaca, Tompkins County, New York

Problem The City of Ithaca, Tompkins County, N.Y., is in the process of developing a flood management plan for the streams that flow through the City. Flooding in the City is an annual problem caused by a variety of distinct and sometimes interconnected reasons. Flooding often is a result of snowmelt and rain during the winter and spring. Slow ice-melt and breakup can lead to ice jams and...

Comprehensive Delineation of Groundwater Source Areas and Times-of-travel to Long Island Streams and Estuaries

Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an...
