FOCJC has chosen the Cabin John Bridge as a symbol in the FOCJC logo, because the historic Cabin John Bridge (built in 1863)  is located at the geographic point where all the water of the Cabin John Creek Watershed flows into the Potomac River.

Cabin John Creek is located in Montgomery County, Maryland. The creek flows through the communities of Rockville, Bethesda, Potomac and Cabin John and drains to the Potomac River and the Chesapeake Bay.

Friends of Cabin John Creek, Inc. (FOCJC) is a volunteer citizen group dedicated to the restoration, preservation and stewardship of the Cabin John Creek watershed, which stretches eleven miles (from the Rockville Metro station down to the Potomac River). Scientific studies have confirmed that the Creek and its eight tributaries are not in good shape. Substantial storm water runoff gushes through the Creek, causing unnatural erosion and sedimentation. The runoff destroys aquatic habitat and flushes away the fish that would otherwise live there. Litter is also a major problem, e.g., posing risks to resident wildlife. The all-volunteer FOCJC organizes cleanups and other activities to improve management of stormwater.

News Highlights

April 2015 - Public Outreach and Stewardship Project

FOCJC in collaboration with the West Bradley Citizens Association, the Cabin John Citizens Association, Cabin John Gardens Cooperative, the Riverhill Homeowners Association, and the Potomac District for Boy Scouts, has received a two-year grant for $42,000 from Montgomery County to help reduce stormwater runoff in the watershed to improve water quality in Cabin John Creek and contribute to County and state efforts to clean up the Chesapeake Bay. Reducing runoff will also reduce or stop flooding of yards and homes in the watershed. Grant funding is provided through the Montgomery County Water Quality Protection Fund. More info here.

January 2015 - MLK Jr Day of Service

Thanks so much to each of you for volunteering at Locust Grove Nature Center during the MLK Jr. Day of Service. You truly honored the spirit of the day: A day on, not a day off. With your help, we collected more than 20 bags of trash, 1 bag of recyclables, 2 tires, 1 metal bar and 2 plastic planters. We covered the paths of the Nature Center with wood chips, and we put numerous wheelbarrows of mulch along the to-be-buried dinosaur-replica for young budding paleontologists. Check out the pictures!

March 22 - H20 Summit

FOCJC participated in the H20 Summit, a free, family-friendly event that is a lot of fun.

Inexpensive field microscope - weighs little since it's mostly plastic, uses natural light for illumination, and its low-power magnification is ideal for macroscopic-sized organisms.
Looks to us like a four-toed salamander - one indicator of a healthy creek!
