Chesapeake Assessment Scenario Tool (CAST)

Allows users to develop and compare scenarios using various best management practices within the Chesapeake Bay watershed.  Results can be used to select practices that reduce the most pollution and are most cost-effective, for use in local planning and/or in implementing Watershed Implementation Plans.  Outputs include nitrogen, phosphorus, and sediment load reductions from all sectors and sources, acres treated, and cost.
