Get Involved: PAST EVENTS

To promote the health and beauty of the Cabin John Creek Watershed, FoCJC has pursued a variety of activities, including annual trash removal days, a Weed Warriors program to remove invasive exotic weeds; quarterly monitoring, and commenting on Montgomery County Department of Environmental Protection (DEP) Cabin John Creek Watershed Restoration Study.
New activities are under development, so subscribe to our free newsletter or check back here to stay up to date!

Monday, August 26, 5 - 7 pm

Every time it rains, thousands of pounds of pet waste is washed into stormdrains that lead directly into our streams, causing pollution in our waterways.  Join us to find out how you and your dog can be Watershed Friendly and get your FREE poop bag dispenser.
