This child item dataset contains a shapefile that delineates ice-margin positions in the Owasco Inlet watershed and surrounding area. Ice positions mostly represent pauses during the final retreat of the ice sheet from the area. Ice-margin positions are delineated by moraines (mostly till) in upland areas and by ice-contact deposits in the valleys.

From 2016 to 2018, the U.S. Geological Survey, in cooperation with The New York State Department of Environmental Conservation, conducted a study of the glacial geology and hydrogeology of valley-fill (sand and gravel) aquifers and surrounding uplands within a 112-square-mile area in southern Otsego and northwestern Delaware Counties, New York, centered around the city of Oneonta. The major valleys include those of the Susquehanna River, Otego Creek, Charlotte Creek, and Schenevus Creek. A variety of data were compiled, collected, and synthesized to provide a broad picture of the glacial deposits, hydrogeologic framework, aquifer occurrence, and water-resource potential in the area. Geospatial datasets (shapefiles) of aquifer extents, wells, surficial geology and glacial features are detailed in child items associated with this data release.

In 2015, the U.S. Geological Survey (USGS), in cooperation with the New York State Department of Environmental Conservation (NYSDEC), began an appraisal of the sand and gravel aquifers within the Owasco Inlet watershed, which covers about 117 square miles (mi2) and drains north directly to Owasco Lake, one of New York’s Finger Lakes. About three-quarters of the watershed is within Cayuga County; the remaining area (southern end) is in Tompkins County. The Owasco Inlet valley stretches about 18 miles (mi) from Owasco Lake south to the divide at Freeville. Major tributaries include Hemlock Creek on the west side of the watershed and Dresserville and Decker Creeks on the east side. A variety of data were compiled, collected, and synthesized to provide a broad picture of the glacial deposits, hydrogeologic framework, aquifer occurrence, and water-resource potential in the area. Geospatial datasets (shapefiles) of aquifer extents, wells, surficial geology and glacial features are detailed in child items associated with this data release.

This dataset contains locations of aquifer boundaries and types of aquifer confinement.

This dataset includes "smoothing points" used in the creation of the Roundout Neversink hydrogeologic framework. Smoothing points were manually added by the project team and were used to enhance interpolated layers using geologic assumptions and include: valley edge points, centerline bedrock points (and where applicable L1 and L2 points), and upland bedrock SSURGO points.

The depth to water table was measured at 276 groundwater monitoring wells (observation and supply) screened in the upper glacial and Magothy aquifers during April and May of 2016. This shapefile consists of the locations of those sites where water levels were measured and includes depth-to-water values which are stored in the attribute table. The shapefile was created and intended for use with geographic information system (GIS) software. The measurement locations and depth-to-water values in this digital data set are also presented in Sheet 4 of Scientific Investigations Map 3398.
