Descriptive namePima County Hydrogeologic Subbasins
File namehgbasin2
Spatial domainPima County
AbstractHGBASIN2 displays hydrogeologic subbasins of Pima County. It is an aggregation of a complimentary dataset (HGBASIN1.shp). Features from HGBASIN1.shp were dissolved on the SUB_BASIN field to create generalized hydrogeologic subbasin boundary features.

See the metadata for HGBASIN1.shp for more information.
Known errors/qualificationsThe hydrogeologic subbasin boundaries of eastern Pima County vary from hydrologic subbasin boundaries in places where information from field studies and the literature detailing subsurficial geologic phenomena are available. This research was conducted by Julia Fonseca at PCFCD.

Boundaries in western Pima County (those areas west of the SUBBASIN dataset found on pygmyowl) are the same as hydrologic subbasin boundaries (as defined by SWA_HGAHGN.shp). As more information related to subsurficial geologic phenomena is made available in this region, hydrogeologic subbasin boundaries may be modified. See maintenance description below.
