Located about five miles south of the Great Falls, the lesser falls have a long history. The area is home to the Chain Bridge River, which crosses between Virginia and D.C.

The area of Little Falls also mark the location where the Potomac River crosses with the Atlantic Seaboard fall line. The fall line, or fall zone, is where he Piedmont and the Atlantic coastal plains join in the eastern United States.

The history of the falls is also expansive -- the first European to explore the Potomac as far north as Little Falls was Captain John Smith of Pocahontas fame. Little Falls can be reached by foot via the C&O Canal and a great view of the Little Falls.
According to the Potomac River Guide, Little Falls is also the river's "head of navigation", meaning that ships can't go navigate farther in the river by going upstream.

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.

A “green” rating demonstrates that the level of E. coli at the time of sampling falls beneath the Virginia Department of Environmental Quality primary contact water quality safety standards as well as the DC and MD Primary Contact Water Quality Standards

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

For the first 5 consecutive weeks, single sample values will be compared against the single sample standard of 410 MPN. After 5 consecutive weeks, the geometric mean will be calculated and compared to the 126 MPN value to determine a pass or fail status. Samples are rated “green” if they fall below these values. Samples over the standard are considered "red" due to their failure to meet criteria, and the increased risk of illness.

Potomac sites that are under DC jurisdiction are rated against these values. As requested by the DC Department of Energy and Environment, site ratings are determined by the geometric mean value, not the single sample value.

A red "special status" update indicates an abnormal situation such as a severe weather event, construction activity, or a combined sewage overflow (CSO) in the past 48 hours. This status means it is extremely likely there are unsafe levels of bacteria in the river, and it is recommended to be extra cautious if you are close to the river or come in contact with the water. A grey "special status" can also mean that there was no data collected that week due to high flow rates, park closures, or inaccessibility of the collection site.

Potomac Riverkeeper Network staff, interns, and volunteers monitor water quality at several locations along the Potomac River in partnership with Alliance for the Chesapeake Bay and other non-profit organizations. The monitoring effort in Virginia and Maryland waters is generously supported by the Virginia Environmental Endowment, National Harbor Marina, Peterson Companies, SP Marine Management, and Hunting Creek Garden Club. Monitoring in District of Columbia waters is supported by the DC Department of Energy and Environment through grant #RFA 2018-1805-WQD-VWQM Project #1 to Anacostia Riverkeeper.

Monitoring occurs every week from May through September. Parameters to be monitored include E.Coli, total coliform, pH, temperature, and turbidity. Detailed monitoring results can be found through the Chesapeake Monitoring Cooperative's Data Explorer, https://cmc.vims.edu/#/home

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 are indicators of fecal contamination by warm-blooded animals including birds and mammals. Sampling sites along the Potomac fall within several jurisdictions and monitoring programs. Each jurisdiction has defined their own water quality standards and each program uses its own method for determining a pass or fail site status. In 2022, each jurisdiction is using the same Primary Contact Water Quality Standards.

We encourage users to explore the sample data in addition to checking the swim guide status. These data can be viewed through the Chesapeake Monitoring Collaborative Data Explorer, https://cmc.vims.edu/#/home
