Name: Open Water Designated Use - Segments Not in Attainment

Display Field: Value

Type: Raster Layer

Geometry Type: null

Description: 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 and have not attained the 1 or any designated use criteria. Attainment of Water Quality Standards is the ultimate goal of the Chesapeake Bay TMDL.
