The EPA has released version 3.0 of the Better Assessment Science Integrating point and Nonpoint Sources (BASINS) software system. BASINS enables environmental professionals to use GIS tools to examine environmental information, analyze environmental systems, and examines management alternatives. This new release allows users and developers to add their own software to the BASINS system, and includes many new features and improvements, including tools to allow users to delineate watersheds, select watershed models, and see and compare the results of several watershed model simulations. Information about BASINS 3.0 is available at www.epa.gov/ost/basins/. CDs with the new version can be ordered from this Web site.
