Brook trout toxicity data from bioassays conducted in Western Adirondack Streams, 2001-03 and 2015-17
This dataset is composed of a single data table containing survival data and ancillary measurements for brook trout bioassays conducted in streams of the Western Adirondack Mountains during 2001-03 and 2015-17. At each stream site, 4 replicate bottles, each containing five young-of-year brook trout, are exposed to ambient stream waters for approximately one month during spring.
Horizontal-to-Vertical Spectral Ratio Soundings and Depth-to-Bedrock Data for Geohydrology and Water Quality Investigation of the Unconsolidated Aquifers in the Enfield Creek Valley, Town of Enfield, Tompkins County, New York, April 2013 - August 2015
From April 2013 to August 2015, the U.S. Geological Survey, in cooperation with the Town of Enfield and the Tompkins County Planning Department, collected horizontal-to-vertical seismic soundings at 69 locations in the Enfield Creek valley to help determine thickness of the unconsolidated deposits and depth to bedrock. The HVSR technique, commonly referred to as the passive-seismic method, is u
Records of Selected Wells for Data Source for Geohydrology and Water Quality Investigation of the Unconsolidated Aquifer in the Enfield Creek Valley, Town of Enfield, Tompkins County, New York, 2013-18
From 2013 to 2018, the U.S. Geological Survey, in cooperation with the Town of Enfield and the Tompkins County Planning Department, collected and compiled well records (306 in total) within and outside the unconsolidated aquifers in the Town of Enfield, New York. Sources of well data included previous USGS groundwater studies, the USGS National Water Information System, and well records obtaine
Data and analytical type-curve match for selected hydraulic tests at an earthen dam site in Southern Westchester County, New York
This data release contains water level displacement data and analytical type-curve matches for selected hydraulic tests that support USGS Open-File Report 2019-1102, "Slug-test analysis of selected wells at an earthen dam site in southern Westchester County, New York." In 2005, the U.S. Geological Survey began a cooperative study with New York City Department of Environmental Protection (NYCDEP
Drought Streamflow Probabilities in Northeast Region
Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.

Detailed Aquifer Mapping Program in Upstate New York
Define the hydrogeology of extensively used (primary) stratified-drift aquifers in upstate NY, and present the information as individual sets of maps at 1:24,000 scale. Each published report describes the hydrogeology of a specific aquifer or segment, and depicts selected hydrogeologic characteristics. Continue the hydrogeologic assessment and mapping of selected principal aquifers in upstate NY.
Geospatial dataset of flood-inundation maps for Cayuga Inlet, Sixmile Creek, Cascadilla Creek, and Fall Creek at Ithaca, New York
Digital flood-inundation maps for a 2.9-square-mile area of Ithaca, New York, were created in 2015-18 by the U.S. Geological Survey in cooperation with the City of Ithaca, New York, and the New York State Department of State. The flood-inundation maps depict estimates of the maximum areal extent and depth of flooding corresponding to selected flood frequencies for Cayuga Inlet, Sixmile Creek, Casc
Data for Impacts of Alewife and White Perch Introductions on Rainbow Trout Growth in the Ashokan Reservoir, Catskill Mountains, NY
This dataset contains the results from aging and back-calculation of length-at-age of scale samples from 492 Rainbow Trout captured in the Ashokan Reservoir between 1952 and 2016. The first five columns contain collection information including an assigned fish number, the year and period of capture, the basin of the Ashokan Reservoir from which a fish was captured, and the length of the fish when
Geospatial Dataset of Water-Table and Potentiometric-Surface Altitudes in the Upper Glacial, Magothy, and Lloyd Aquifers of Long Island, New York, April-May 2016
The U.S. Geological Survey (USGS) is providing online maps of water-table and potentiometric-surface altitude in the upper glacial, Magothy, Jameco, Lloyd, and North Shore aquifers on Long Island, New York, April-May 2016. Also provided is a depth-to-water map for Long Island, New York, April-May 2016. The USGS makes these maps and geospatial data available as REST Open Map Services (as well as HT
Geospatial datasets of AUV observations including bottom dissolved oxygen in Great South Bay, Long Island, New York, August 2016
This dataset provides locations and values of water quality parameters from a four-day survey conducted between August 23, 2016 and August 26, 2016 using an Autonomous Underwater Vehicle (AUV) in Great South Bay, New York. Measured parameters include bottom dissolved oxygen (DO), salinity, specific conductance, water temperature, and pH. During the four day period, data was collected along 15 tr
Geospatial Bathymetry Dataset and Elevation-Area-Capacity Table for Schoharie Reservoir, 2014
From 2013 to 2015, bathymetric surveys of New York Citys six West of Hudson reservoirs (Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie) were performed to provide updated capacity tables and bathymetric maps. Depths were surveyed with a single-beam echo sounder and real-time kinematic global positioning system (RTK-GPS) along planned transects at predetermined intervals for each
