Chesapeake Bay Health Improves


BALTIMORE, Md. — An improved grade for the Chesapeake Bay could mean a reverse in its declining health. 

The Chesapeake Bay health improved to a C in 2012, according to an assessment by scientists at the University of Maryland Center for Environmental Science. This is up from a D+ in 2011. Overall, the Bay health appears to have been slowly increasing since 2006. 

The health of the Bay improved from 38% in 2011 to 47% in 2012. Close to all of the health indicators, including dissolved oxygen, water clarity, total nitrogen, total phosphorus, the amount of algae in the water and the benthic community improved last year. 

The annual report card uses seven indicators to rate 15 reporting regions of the Bay. Those indicators are combined into one index of overall health.
