Surficial geology and ground-water availability in the Allegheny River basin and part of the Lake Erie basin, New York

New York State 's need to develop a groundwater management program for protection of its aquifers led in 1985 to a cooperative program between the U.S. Geological Survey and the New York State Department of Environmental Conservation (through regional planning agencies) to publish data from previous studies. The two maps presented are from original compilations done in a 1967 study. Sheet 1 depicts the surficial geology as mapped in 1967; sheet 2 shows the groundwater availability (well yield) throughout the basin. These maps are presented at 1:250 ,000 scale for compatibility with published maps of adjacent river basins.
