Discontinous stratified-drift aquifers underlie 66 of the 484 square miles of the river basin. Saturated thickness of stratified drift is locally greater than 100 feet but generally is less. Trans- missivity exceeds 4,000 feet squared per day in some aquifers but is generally less than 1,000 feet squared per day. Purpose: This data can be used for analysis, producing maps, and illustrations for hydrologic studies and resource management. Supplemental_Information: Transmissivity of stratified-drift aquifers, in feet squared per day (ft2/d), were estimated from test-boring logs by calculating hydraulic conductivity for specific intervals, multiplying these values by the saturated thickness of the interval, and summing the results. Transmis- sivity values report by published engineering consultants, were used as well as calculating transmissivites from unpublished aquifer test data. The transmissivity coverage is a polygon coverage where each polygon represents a range a transmissivity; for example, 0 to 1,000 ft2/d. Some polygons are hills of till that protrude the stratified-drift and, therefore, have a transmissivty of nearly 0ft2/d. Transmissivities were interpreted on 1:24,000 scale-stable mylar USGS quadrangle maps and digitized into a geographic information system (GIS), using ARC/INFO version 7.0. The quadrangle maps were then merged into one study-wide coverage and edited for errors and discrepancies. The finished study-wide coverage were clipped and erased with the hydro- graphy coverage ( 1:24,000 scale hydrography representaion obtained from converting USGS Digital Line Graphs (DLG) into ARC/INFO cover- ages), so that transmissivity did not extend into rivers (those that were wide enough to be a polygon in the hydrography coverage) or other surface water bodies such as lakes or ponds. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ARC/INFO format, this metadata file may include some ARC/INFO-specific terminology. Related_Spatial_Data_Sets: Other data sets available from this study include aquifer boundaries, seismic lines, saturated thickness, and water table contours.
