Welcome to BayTAS v.2.0. BayTAS provides access to nutrient load, BMP, and supporting data specific to implementation of and progress toward the Chesapeake Bay TMDL. Future versions of BayTAS will provide access to additional data, including point source, facility, and permitting data.
Register here for access to publicly available TMDL data. Users requiring additional access should contact the site administrator with that request (feature disabled in beta version).
