1994 Study Units - Final Data Aggregation

Ancillary GIS data for 1994 NAWQA ground water studies (LUS, SUS)

This page contains various summary tables pertaining to ancillary data for ground water polygons (Land Use Studies [LUS] and Subunit Surveys [SUS]) in the NAWQA study units that began in 1994. There are two kinds of ground water network polygon coverages: BND coverages, which represent the entire areal extent of the hydrogeologic unit defined for study and TRG coverages, which delineate the targeted land use within the BND. The polygon coverages are also available.
