Dredging Up Some Natural History

A little trivia. Every single lake in Maryland is man-made. You can look it up here. The big ponds around these parts are no exception and must be periodically dredged to remain, well, lakes. It's a messy business. The Columbia Association is drawing up plans to work on lakes Elkhorn and Kittamaqundi so they don't revert to marshlands, according to the Sun. Some nearby residents don't want the gunk in their backyard.
