New York Water Science Center

Our New York Water Science Center priority is to continue the important work of the DOI and the USGS, while also maintaining the health and safety of our employees and community.  Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices.

The water quality of selected streams in the Catskill and Delaware water-supply watersheds in New York, 1999–2009

From October 1, 1999, through September 30, 2009, water-quality samples were collected, and discharge was measured at 13 streamgages within the Catskill and Delaware watersheds of the New York City water supply system. The Catskill and Delaware watersheds supply about 90 percent of the water needed by 9 million customers. On average, 59 water-quality samples were collected at each station during e

Turbidity–suspended-sediment concentration regression equations for monitoring stations in the upper Esopus Creek watershed, Ulster County, New York, 2016–19

Upper Esopus Creek is the primary tributary to the Ashokan Reservoir, part of the New York City water-supply system. Elevated concentrations of suspended sediment and turbidity in the watershed of the creek are of concern for the system.Water samples were collected through a range of streamflow and turbidity at 14 monitoring sites in the upper Esopus Creek watershed for analyses of suspended-sedim

Cyanobacteria, cyanotoxin synthetase gene, and cyanotoxin occurrence among selected large river sites of the conterminous United States, 2017–18

The U.S. Geological Survey measured cyanobacteria, cyanotoxin synthetase genes, and cyanotoxins at 11 river sites throughout the conterminous United States in a multiyear pilot study during 2017–19 through the National Water Quality Assessment Project to better understand the occurrence of cyanobacteria and cyanotoxins in large inland and coastal rivers. This report focuses on the first 2 years of

Methods for Estimation Flood Magnitude and Frequency at Ungaged Streams in New York, excluding Long Island

Summary: Extreme flooding can threaten life and property in flood-prone areas, as well as cause damage to critical infrastructure along roadways and canals. The effective management of these areas, and appropriate design of structures along rivers and streams, relies on understanding the magnitude and frequency of floods at gaged locations, and the ability to estimate these data at ungaged strea

Geohydrology of the Valley‐fill Aquifer in the Lower Fall Creek Valley, Town of Dryden, Tompkins County, New York

PROBLEM The valley‐fill aquifer in the lower Fall Creek valley (designated as aquifer 4, fig. 1), within the Towns of Dryden and Groton, was mapped by Miller (2000) and identified as one of 17 unconsolidated aquifers in Tompkins County that need to be studied in more detail. The east end of the valley (near the Tompkins and Cortland County border) is on the backside of a large morainal plug, which...

Water-Resource and Road-Condition Monitoring of Alternative Treatments for Road Deicing

Introduction The New York State Department of Transportation (NYSDOT) is evaluating alternative treatments for road deicing with the goal of reducing the impact of this activity on the State’s water resources. The NYSDOT has requested support from the U. S. Geological Survey (USGS) in monitoring the effects of these alternative treatments on the water resources. In the past, the USGS has cooperat
