Willett Branch – Norwood Park

Bethesda, Maryland

Find the Willett Branch site downstream from the Bethesda Pool, near Norwood Park in Chevy Chase. You can access the creek by scrambling down the banks. There you will be welcomed by a sparking creek tumbling over rocks. There are little pools, stepping stones and plenty of places to hunt for macroinvertebrates or just sit and read a book.

This monitoring site is located at the northern most point of the Little Falls Stream Valley Park. Though most of the Willett Branch is channelized in concrete ditches or enclosed in storm drains, there is a lovely short natural stretch on the Little Falls Stream Valley Hiker/Biker. On weekends, the Parkway is closed, so come and enjoy the creek and a walk or bike-ride on 1 miles of closed parkway.

Willet Branch joins the Little Falls Creek north of Massachusetts Ave on Little Falls Parkway.

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

Willett Branch – Norwood Park is sampled weekly from June 1st to September 15th.

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.
