This graphical interface to the Phase 7 Watershed Model inputs is provided by the Chesapeake Bay Program to facilitate review of the data by the Partnership. The Chesapeake Bay Program intends for this interface to facilitate transparency in the Watershed Model and offer a common, public platform for reviewing data.

Select an input dataset from the menu to view data visualizations and download the source tables and metadata. Use the tabs at the top to switch between the Phase 6 and Phase 7 versions.

Captions for most graphs identify the CBP workgroup responsible for that input. Please contact the workgroup chair and coordinator if you have questions about specific data. Need assistance using this interface or have related questions? Contact Andy Fitch (afitch@usgs.gov).

Data are updated when the new versions are released, and as new data become available. Functionality upgrades are made on a rolling basis in response to comments and requests from users.

Choose an input dataset from the menu to get started.
