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 2014 - Creek Cleanups

Thanks to everyone for cleaning up Cabin John Creek and its tributaries! View the pictures of our cleanup crews and all the trash they pulled out of the watershed. To organize a new cleanup location in the Cabin John Creek watershed, email us.

March 21 2014 - New Newsletter

The first issue of our newsletter is available. Sign up to stay informed. (You won't be inundated. We expect the newsletter to appear no more than once a month and each newsletter will contain a link to control or end your subscription.)

March 22 - H20 Summit

FOCJC participated in the H20 Summit, a free, family-friendly event that is a lot of fun. Held annually, the Summit introduces residents to their local watershed groups, volunteerism, green exhibitors and watershed improvement activities occurring in their communities. We all learn about stream health and how our everyday actions effect stormwater pollution and our ecosystem. If you missed it this year, we look forward to doing it again next year!

March 5 2014 - New Domain Name

FoCJC has a new domain name: We anticipate it will be easier to remember than our old one. Along with that, we also have a new contact address: Feel free to send us questions and comments. Of course, you can continue to use our facebook page which is particularly good if you want your questions and comments to appear publicly. See our full list of contacts above.

February 17 2014 - Communications Redesign

FoCJC held a work session on redesigning the website, communicating with the community, and better integration of calendars and maps. Look for lots of improvements in the near future!

Pictures From Our Most Recent Stream Cleanup

Sponsored jointly by FoCJC and Montgomery County Department of Parks

We cleaned up the Creek near Goya Drive, Potomac on a lovely Sunday afternoon, September 29th. Thanks to our volunteers and the support of the MC Dept of Parks.

Michael Northridge's field report: "I estimate that a total of approx. 25 volunteers participated, ranging from young kids through to a senior citizen couple who live nearby. Among the trash pulled out were an old can of paint thinner, one auto tire, one buried rotting bicycle tire, part of an old wheelbarrow, a shower curtain rod, a hub cap, an auto muffler, lots of broken styrofoam, and many many many plastic bottles. Rosie pulled out a long rusty construction rebar. I used my shovel in the water to get at a long garden hose that was mostly buried under muck and stones. I also used my saw to extricate a Plymouth fender that was stuck in some branches in the creek. I went back to the creek a few days later and hauled out the large truck wheel. ;-) In total, I'd guess about 8 bags of recyclables, about 20 bags of trash, plus two large containers filled with the larger items (e.g., tire, fender, rebar, etc)."

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!
