 The Chesapeake Bay is getting healthier, according to a new report card. WTOP's Kate Ryan has that story. For more than 20 years, the best grade the health of the Chesapeake Bay got was a C. That's according to Bill Dennison with the University of Maryland's Center for Environmental Science. He said the new grade of a C-plus is a recognition of progress in some areas of the bay and its tributaries, for example, at Susquehanna Flats in northeastern Maryland.
