Summary:The U.S. Geological Survey (USGS) New York Water Science Center (NYWSC) operates a monitoring network of streamgages in New York where water-resources information, collected in near-real time, can be used for computing long-term low-flow statistics. This study aims to determine low-flow, mean annual and mean monthly flow statistics and for all continuous streamgages in New York State, and to complete a thorough statistical analysis of potential trends in these data. Regional regression equations will be developed to estimate the computed statistics for ungaged locations in New York from the relation of computed statistics at gaged locations to various physical and climate characteristics of that region....

Problem Surface-water information is needed for planning, design, hazard warning, and operation and management in water-related fields such as water supply, hydroelectric power, flood control, irrigation, bridge and culvert design, wildlife management, pollution abatement, flood-plain management, and water-resources development. Appropriate historical and real-time surface-water data, such as stream flow and stage, reservoir levels, and water temperature, are necessary to properly assess, manage and protect water resources. Objectives Collect timely and high quality surface-water data for (1) assessment of water resources; (2) operation of reservoirs or industries; (3) forecasting flow; (4) disposal of wastes...

The coastal areas of southeastern New York (fig. 1) are highly vulnerable to tidal flooding (fig. 2). Timely evacuation of people from flood-threatened areas in advance of approaching hurricanes and nor'easters (northeast coastal storms) requires adequate flood-warning time. To begin addressing this need for immediate information on coastal flooding, the U.S. Geological Survey (USGS), in cooperation with the Town of Hempstead Department of Conservation & Waterways, Village of Freeport, and New York State Department of Environmental Conservation, has operated a network of real-time tidal water-elevation and meteorological stations since 1997 in the coastal areas of Long Island and New York City. Each tidal water-elevation...

This U.S. Geological Survey (USGS) data release contains batch formatted annual peak streamflow data (PkFlows_AllSites.txt) for the respective periods of record (through the 2020 or 2021 water year) for seven USGS streamgages in the upper Esopus Creek watershed in upstate New York. This data release also contains batch formatted specification (PkFlows_AllSites.psf) and output (PEAKFLOWS_ALLSITES.PRT) files from log-Pearson type III (LPIII) flood-frequency analysis of the annual peak streamflow data from version 7.3 of the USGS PeakFQ software (https://water.usgs.gov/software/PeakFQ/), and a csv file (FloodFrequencyEstimates.csv) with estimates of flood magnitudes for selected annual exceedance probabilities from...

Problem Previous hydrologic studies have indicated that there may be sufficient water resources underlying Queens, Kings, Richmond, New York, and Bronx Counties for use as a supplemental water supply in times of drought or other emergency. An extensive ground-water and surface-water monitoring program is necessary to provide a comprehensive hydrologic data set for use in ongoing and future ground-water investigations. Objective The project will provide a continuous hydrologic data set needed for resource assessment, planning, and protection. To meet this objective the U.S. Geological Survey (USGS), in cooperation with the New York City Department of Environmental Protection, maintains and operates a network of approximately...

Description of Study The objective of this study was to define specific conductance in stream water under low streamflow conditions in Central New York. The study area covers parts of six counties in the Southern Tier region of New York State (fig. 1). This survey covered a range of watershed areas and land use types, and specifically targeted low-flow periods during the summer as the flow would be mostly derived from groundwater discharge at this time and represents the upper limit of conductance that can currently be expected. This study was funded by the New York State Department of Environmental Conservation. Methods The network of sites sampled was created using ARCMAP software. Over 280 sites were selected...
