Maps of 2024 Tidal Water Quality Change

Description

The Chesapeake Bay Program (CBP), Maryland Department of Natural Resources (MDDNR), Virginia Department of Environmental Quality (VADEQ), Old Dominion University (ODU), District of Columbia Department of Energy and the Environment (DC DOEE), and Metropolitan Washington Council of Governments (MWCOG) collaborate annually to produce bay-wide summaries of water quality trends in the tidal waters. These annual estimates at more than 150 stations for nutrients, dissolved oxygen, Secchi depth, chlorophyll a and other parameters help gauge the health of the bay and identify changes due to management actions and climate. The 2024 Tidal Trends Summary document attached below summarizes these results. Additional tools are available to explore the tidal trends results including baytrendsmap and the Watershed Data Dashboard, Tidal page.
