This is the first site monitored by ANS. It is located in Watts Branch Stream Valley Park upstream of the Glen Road Bridge in Potomac, Maryland. At this point, WattsBranch is a third order stream, meaning it takes in flow from smaller tributaries. Since the site was opened, increased housing development upstream has contributed non-point source runoff, which has affected bank and streambed stability, habitat integrity, and water quality.
