The Chesapeake Bay watershed totals about 64,000 square miles, covering parts of six states and the District of Columbia. 

On December 29, 2010, the U.S. Environmental Protection Agency established the Chesapeake Bay Total Maximum Daily Load (TMDL)  that initiates sweeping actions to restore clean water in the Chesapeake Bay and the region's streams, creeks and rivers. 

The Chesapeake Bay TMDL is the largest and most complex TMDL in the US, and will set a precedent for TMDLs in other estuaries. Find out more by clicking here.
