Chesapeake Bay Segmentation Scheme (For 303d listing - 92 segments)
Date created: June 4, 2008The 92-segment scheme for the Chesapeake Bay and its tidal tributaries used for dissolved oxygen and water clarity assessments in the most recent 303d/305b listing efforts of the four Bay tidal jurisdictions is documented here. The 92-segment scheme was derived from 1) the 2003 published 78-segment scheme with the addition of jurisdictional boundary lines imposed to create 89-segments, then 2) additionally includes only split segments agreed upon for the tidal James and Potomac rivers.
