MAP SERIES 1

Map 1—This map provides the location of major drainage 

basin divides in Genesee County (Oatka, Black, Tonawanda, 

and Oak Orchard Creek watersheds) and the location of 

bedrock units and contacts, as determined by the New York 

State Geological Survey (NYSGS) (Cadwell, 1988). 

Locations of bedrock contacts are approximate owing to 

scalar differences between the original NYSGS map and 

these quadrangle maps. Where possible though, adjustments 

to these contacts have been made on the basis of soil 

descriptions and limited field inspection. Also shown is the 

location of agricultural land uses (cropland, hay, and pasture, 

in light brown shading), and the “shallow-to-bedrock” soils 

are shown using the hachured shading. These thin soils have 

infiltration rates of 1.42 to 5.67 inches per hour (in/hr). Four 

additional “shallow-to-bedrock” soils (Aurora, Benson, 

Wassaic, and Rubbleland) are shown because they have been 

associated with manure application and groundwater 

contamination in Genesee County, even though they have 

lower infiltration rates than those listed above. Karst features 

are shown with either a 500-foot (ft) radial “buffer” area, if 

there is no stream course associated with the feature or a 

subbasin area that has been delineated if the karst feature 

had a stream course flowing into it that was discernible from 

the U.S. Geological Survey National Hydrography Dataset. 

These subbasins contribute water, and provide possible 

contaminant transport to the carbonate-rock aquifer. Finally, 

the location of any documented groundwater-contamination 

occurrence is shown.
