From 2013 to 2015, bathymetric surveys of New York City’s 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 reservoir. A separate set of echo sounder data was collected along transects at oblique angles to the main transects for accuracy assessment. Field survey data was combined with water-surface elevations in a geographic information system to create three-dimensional surfaces representing reservoir-bed elevations in the...

Survey of velocity and bathymetry in Hoover Reservoir, ADCP source data, Columbus, OH (August, 2015)
These data were collected using a 600 kHz Rio Grande ADCP (acoustic Doppler current profiler) in mode 12 from a moving boat. The data were georeferenced with a Hemisphere A101 Smart Antenna differential GPS. These data were processed with Teledyne RD Instruments' software, WinRiver II. These data were collected concurrently with several water quality parameters that were collected by an autonomous underwater vehicle (AUV) in the same reach. This data release supports the following publication: VonIns, B.L., and Jackson, P.R., 2017, Response of currents and water quality to changes in dam operations in Hoover Reservoir, Columbus, Ohio, August 24–28, 2015: U.S. Geological Survey Scientific Investigations Report 2017–5027,...
These datasets were created in support of the U.S. Geological Survey's (USGS) Next Generation Water Observing System (NGWOS) for the Delaware River Basin pilot study (Eberts, Wagner, and Woodside, 2019). The NGWOS utilizes real-time data, improved computational capabilities, and new technologies such as unmanned aerial vehicles (UAV) and autonomous underwater vehicles (AUV) to provide information on water quality and/or quantity, in more locations, quickly and efficiently (Eberts, Wagner, and Woodside, 2019). Combined with advanced modeling applications, the NGWOS will be an important tool for water-resource managers and emergency management. In this study, water-quality and bathymetric data were measured with an...
The Stream Conditions of Chester County Biological Monitoring Network was established by the U.S. Geological Survey and the Chester County Water Resources Authority in 1969. Benthic-macroinvertebrate, habitat, and stream chemistry data were collected annually from 1998-2021 at 18 fixed location sites. Additionally, nine flexible location sites were selected and sampled annually from 1998-2021. Some of the flexible location sites were sampled more than once over the study period. All data were collected in the fall months (October-November) during baseflow conditions. The benthic-macroinvertebrate data collected was used to calculate six metrics and to establish an index of biotic integrity for each sample, while...

This folder contains water-level recovery data for selected hydraulic tests that support USGS Scientific Investigations Report 2020-5087, "Transmissivity Estimated from Brief Pumping Tests of Domestic Wells and Compared with Bedrock Lithofacies and Position on Hillsides in the Appalachian Plateau of New York." These data are part of a data release that contains observed water-level recovery data in 52 wells, matched to theoretical type curves defined by postulated values of aquifer transmissivity and storage, that together constitute the database for USGS Scientific Investigations Report 2020-5087. The water-level recovery data were collected after 13 to 132 seconds of pumping. Five of the wells were also test-pumped...

From 2016 through 2018, the U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, collected horizontal-to-vertical seismic soundings at 71 locations in the major valleys in the Oneonta area, Otsego and Delaware Counties, New York to help determine thickness of the unconsolidated deposits and the bedrock surface elevation. The HVSR technique, commonly referred to as the passive-seismic method, is used to estimate the thickness of unconsolidated sediments and the depth to bedrock (Lane and others, 2008; Fairchild and others, 2013). The passive-seismic method uses a single, broad-band three-component (two horizontal and one vertical) seismometer to record ambient seismic...
