The city of Cortland is located in Cortland County, New York. Previous USGS reports here include Water-Resources Investigations Report 96-4255 (Miller and others, 1998), and Open-File Report 81-1022 (Miller and Brooks, 1981). The five child pages below break the data up into georeferenced and digitized previous report data, interpreted geologic information, well logs, supplemental point data, and interpolation statistics.

Digital hydrogeologic datasets were developed for the Cincinnatus study area in upstate New York in cooperation with the New York State Department of Environmental Conservation. These datasets define the hydrogeologic framework of the valley-fill aquifer and surrounding till-covered uplands within the study area. Datasets include: bedrock elevation raster, lacustrine silt and clay top and bottom elevation rasters, LIDAR minimum elevation raster, lacustrine extent polygon, valley-fill extent polygon, and surficial geology polygons. An alternate geologic interpretation was considered for modeling purposes. An alternate lacustrine extent and top and bottom elevation rasters are included within this data release. Elevation layers were interpolated at 125-foot discretization to match the model grid cell size.

The Jamestown study area is located within the counties of Chautauqua and Cattaraugus, New York. The predominant population center is the city of Jamestown. Previous USGS reports here include Open-File Report 82-113 (Stelz and others 1982) and Bulletin 58-1960 (Crain, 1966) The five child pages below break the data up into georeferenced and digitized previous report data, interpreted geologic information, well logs, supplemental point data, and interpolation statistics.

This data release shows the digital hydrogeologic datasets were developed for the eight study areas in upstate New York in cooperation with the New York State Department of Environmental Conservation. These datasets define the hydrogeologic framework of the valley-fill aquifer and surrounding till-covered uplands within the four study areas. Also included within are the input data that was necessary to create and interpolate the hydrogeologic framework. The input data is provided as point feature classes, and previously published report georeferenced files along with the digitized data as line or polygon feature classes. The data release is broken into eight child item pages; one for each model area. Each child item contains the data pertaining to that study area. In addition to shapefiles, feature classes were provided for convenience to some users. These feature class datasets were not explicitly outlined in the data release and may have subtle differences to shapefiles due to inherent differences in file types (i.e. character limitations in shapefiles vs feature class files).
