Maryland released its annual Chesapeake Bay Health Report Card on May 18, 2010. The Chesapeake Bay showed broad water quality improvements in 2009, receiving its highest mark since 2002 from the annual Chesapeake Bay Health Report Card. At the same time, the state launched StreamHealth, a website to help Maryland residents learn about the health of their streams and take action to improve them.
The report card is an annual analysis conducted through the EcoCheck partnership between University of Maryland Center for Environmental Science and NOAA Chesapeake Bay Office. Results are based on data collected by state and federal agencies through the Chesapeake Bay Program. The 2009 report noted improved conditions in eight Bay regions and degraded conditions in two, earning the Bay a grade of “C” for overall health.
