The Bay and its tidal tributaries can be divided into 92 segments. Each of these segments contains up to five “designated uses,” including deep channel; deep water; open water; shallow water; and migratory fish, spawning and nursery. Each of these designated uses—also known as aquatic habitats—has its own set of criteria for dissolved oxygen, water clarity/underwater grasses and chlorophyll a designed to protect those uses. This map shows the segments that have been designated as attaining all designated use criteria. Attainment of Water Quality Standards is the ultimate goal of the Chesapeake Bay TMDL. |
