ACFBLUSFO1_BND, ACFBLUSFO1_TRG, CCPTLUSAG1A_TRG, and CCPTLUSAG1B_TRG have been replaced. The boundaries DID NOT change. For the ACFB coverages, the SUCODE was changed from acfbreffo3 to acfblusfo1. For the CCPT coverages, the STAID item was dropped from the .pat files.

Note: (June 21, 2006)

DLMVLUSCR1_TRG and WMICLUSAG2_TRG have been replaced. The boundaries DID NOT change. However, the NULL polygon in each coverage was changed so that SUCODE = ' ' and INSIDE = 0.

Note: (June 22, 2005)

SANTLUSRC1_BND has been replaced. The boundary should be the same as SANTSUS1_BND, not the same as SANTSUS2_BND.

Maps of cycle 1 ground water study areas (9.6mb PDF file): The PDF file contains one page size map per network, sorted by study unit. Each map shows BND, TRG if applicable, and wells. Maps were generated at various dates from 2002-2004 so some might not reflect the wells in the current data base. Also, no distinction is made between cycle 1 wells and cycle 2 wells.
