User guide (pdf format about 500K)

Directory	Dir Size	Contents
BASINS*	78.4 MB	Contains all of the BASINS v.1 data sets for RWQCB Region 3, the BASINS ArcView project file, and associated documentation. NOTE: Some of the data sets on the BASINS CD could not be properly re-projected to UTM. To retain the integrity and operability of the full BASINS product, therefore, it is reproduced here in its original Albers projection. Data sets from this directory can therefore not be used directly with other WATER data. The BASINS data sets that could be converted to UTM have been included in other directories (and are noted as coming from the BASINS CD). You must download the entire BASINS directory and place it on your C:/ drive (as in C:\BASINS) for the BASINS project to work properly. For more information about BASINS, and access to BASINS v.2, visit EPA’s BASINS web site.
