And when did the bell curve grading system become so deformed that 53% is a C?
But the folks at the University of Maryland Center for Environmental Science declared that the overall health of the Chesapeake Bay improved in 2015, giving it a C (53%) in 2015, one of the three highest scores since 1986. Only 1992 and 2002 scored as high or higher, both years of major sustained droughts.
Thus, the recent May rains do not bode well for the bay. Many farmers, especially those in the Susquehanna basin, do not fence their cattle out of streams or use no-till methods.
