Mattawoman Creek is one of the most pristine water bodies in southern Maryland. Its drainage has been designated as a “stronghold watershed” by the state. But in 2009, American Rivers named it the fourth most threatened river in the nation. So when a 773-acre property along the river was slated for development, a group of concerned locals turned to TPL for assistance with a conservation solution. Working with a cooperative landowner, TPL was able to help the Maryland Department of Natural Resources add the property to the Myrtle Grove Wildlife Management Area in 2011, ensuring the health of this important tributary to the Chesapeake Bay.
