Delmarva — The Chesapeake Bay received an overall health grade of C in 2025, down from a C+ in 2024, according to the University of Maryland Center for Environmental Science’s annual report. The report assesses ecology, society, and economy indicators across the watershed, which earned a C+ this year. Most indicators showed declines compared to last year, influenced by extreme weather conditions including intense rainfall, drought, and heat waves. Despite the recent drop, long-term data indicates the bay has steadily improved since the 1980s. Progress has been driven by regional management and restoration efforts such as wastewater treatment upgrades, nutrient and sediment reduction programs, seagrass restoration, and oyster plantings. Several regions, including the Elizabeth, James, and Upper Bay areas, continue to show positive trends. Economic data revealed job growth but persistent income inequality among communities. Heat vulnerability was the most concerning societal factor, with some areas facing increased stress due to higher temperatures and reduced tree canopy. The report remains an important resource for conservationists and policymakers as Chesapeake Bay restoration goals reach a key milestone in 2025. A detailed report with recommendations will be submitted by April 2026.
