What to know about Scientists forecast milder Chesapeake Bay dead zone in 2026

Scientists from several institutions have forecast a relatively mild dead zone in the Chesapeake Bay for 2026, citing lower nitrogen levels and reduced river flows. The report explains the causes of hypoxia and highlights the role of the Center of Excellence in Environmental Forecasting in monitoring and predicting bay conditions.

What happened

Scientists forecast milder Chesapeake Bay dead zone in 2026 Gaby Clark Scientific Editor Andrew Zinin Lead Editor Scientists at William & Mary's Batten School & VIMS, FlowWest and the University of Maryland Center for Environmental Science recently announced…

Why it matters

According to the newly released Chesapeake Bay 2026 Hypoxia Forecast, dead zone severity is predicted to rank among the lowest 10% of years since extensive monitoring began in 1985 and to be about 31% below the long-term average.

Common ground

This forecast complements the annual Chesapeake Bay Dead Zone Report Card produced by the Batten School & VIMS and FlowWest each fall and marks a return to the annual spring forecast that began in 2007 using a model developed by the University of Michigan.
