A study was conducted to provide detailed mapping of glacial aquifers associated with the Fairport-Lyons channel system in Wayne, Ontario, and Seneca Counties, New York. The study was part of the cooperative Detailed Aquifer Mapping Program between the U.S. Geological Survey (USGS) and the New York State Department of Environmental Conservation (NYSDEC). The objective of the study was to characterize the hydrogeology of the Fairport-Lyons channel and inter-drumlin aquifer system and to present the results as an electronic 1:24,000 scale map, hydrogeologic sections, and a summary report. The spatial extent and hydrogeologic framework of this valley-fill aquifer was delineated using existing data, including soils maps, well records, geologic logs, topographic data, and published reports. This data release contains digital datasets for the areas of surficial sand and gravel with water-resource potential, eskerform features, areas of sand and gravel or sand pits, delineated areas of postglacial and glacial deposits, and records of selected wells within the study area and traces of the hydrogeologic sections referred to in the study. These digital datasets support USGS SIR 2021-5086, "Hydrogeology of aquifers within the Fairport-Lyons channel system and adjacent areas in Wayne, Ontario, and Seneca Counties, New York."
