The University of Maryland Center for Environmental Science released its 19th annual Chesapeake Bay and Watershed Report Card, giving the Bay an overall grade of C (50%) and the Watershed a C+ (57%). This marks a five-point decline from last year, attributed to extreme rainfall and heat, leading to runoff issues. Despite this downturn, long-term improvements are noted in six regions and indicators like dissolved oxygen and aquatic grasses. Most indicators show positive trends over time.
