Description:      Aquifers, as determined/defined by DLNR/DOWALD.  (Note:  DOH
                  maintains another version of aquifers, which is more resource-
                  oriented in nature, and which has different boundaries than 
                  the DLNR/DOWALD version, which is more administrative in 
                  nature).

History:          Digitized in 1995 in Arc/Info  using ArcEdit by DLNR-DOWALD 
                  from island-wide maps of varying scales.  Updated by DOWALD in
                  March,2000.  Updated by CWRM in February, 2005 to add the island
                  of Molokai.  Coastline revised by CWRM, Jan 2006.
		  Corrected Aquifer System Names Kealia and Paomai; corrected Aquifer
		  Sector Name Kamao, Sep 2008.
		  Converted to poly and line shapefiles; updated system yield values
