Little Falls Creek Below Massachusetts Ave

Bethesda, Maryland

Little Falls Creek below Massachusetts Ave is located in the beautiful 160-acre Little Falls Stream Valley Park at the heart of the Little Falls Watershed just off the hiker/biker trail below the Massachusetts entrance to the park.

The LFSV Park has no facilities but is home to the lovely 3.5 mile Little Falls Stream Valley trail along the creek. The trail starts in Bethesda, MD, near Norwood Park and runs along the Little Falls Parkway, then parallel with the Capital Crescent trail all the way to MacArthur Boulevard in Washington, DC. The area is wonderful for kids, walking dogs, jogging, biking, or simply taking a stroll. Lots of wildlife has been spotted here, including owls, foxes, and various songbirds and ducks.

There is parking at the gravel parking lot at the intersection of Massachusetts Ave and Little Falls Parkway in Bethesda, MD. Head downstream to find the site. Look for the second bench where there is easy access to the creek.

COVID-19

Keep your distance from other people.

Practicing social distancing is still essential. Only go to the beach if you are able to keep 6 feet or 2 meters away from others. Follow the instructions provided by your local health authorities. If your community has asked that you remain indoors and away from others, do so. Spending a day in any crowded place is the worst thing we can do for our most vulnerable right now and will counter our efforts to curb the virus’s spread.

Monitoring Frequency

Little Falls Creek Below Massachusetts Ave is sampled weekly from June 1st to September 14th.

Source Information

Little Falls Watershed Alliance has trained volunteers monitor water quality at several locations in the Little Falls Watershed, a sub-watershed of the Potomac. Monitoring occurs every other week from July through mid-September. Parameters to be monitored include levels of E.Coli, pH, and temperature. The samples are processed by the Anacostia Riverkeeper water quality lab.


The primary parameter of concern is E. coli, a fecal coliform. E. coli is measured in terms of the Most Probable Number /100 ml water and high levels are an indicator of fecal contamination by warm-blooded animals like birds and mammals.


The MD Primary Contact Water Quality Standards are as follows:
• E. coli single sample value = 410 MPN/100mL
• E. coli geometric mean = 126 MPN/100mL


The Little Falls and Willett Branch are rated against these values. PASS indicates the E. coli single sample value is less than or equal to 410 MPN/100mL. FAIL indicates bacteria counts of over 410 MPN/100mL.
