"The Chesapeake Bay’s recovery took a step back in 2018, but the estuary retained its “C” grade on an annual report card from the University of Maryland Center for Environmental Science.

With nearly twice as much rainfall as normal across the state last year, the bay saw increases in nitrogen and phosphorus levels and declines in abundance of underwater grasses and many types of aquatic life. The surges of precipitation throughout the year washed large amounts of pollution and nutrients into the bay from across its 64,000-square mile watershed, fouling waters and disrupting its ecology.

The Chesapeake’s overall report card score declined for the first time since 2013, falling from 54% to 46%. A score of 80% or better would earn an A grade."
