What is a watershed?
A watershed is the land region draining into a stream, river or body of water. There are 20 sub-watersheds in the Columbia area. The main two watersheds are the Little and Middle Patuxent rivers, which are part of the Chesapeake Bay watershed. While Columbia has an area of 28 square miles, the watershed draining area is 49 square miles.


What we're doing.
Columbia Association developed the Columbia Watershed Management Plan, or CWMP, with the objective of protecting and restoring the waters of Columbia. The plan uses two distinct approaches. The first is identifying and restoring the watershed infrastructure, performing intensive investigations to find pollution sources and designing restoration projects to reduce them. The second is educating and involving residents and property owners in watershed stewardship.
