A flood from above...........and one from below.............just ask the phantom of the opera................



The creek rises from a spring near Laytonsville in Montgomery County, in the U.S. state of Maryland, and joins the Potomac near Georgetown and the Watergate inWashington, D.C. Beginning in the Derwood–Rockville area in Maryland, the creek flows through Rock Creek Regional Park southward to the D.C. boundary. About 9 miles (14 km) of the creek flow though Rock Creek Park in Washington, where it is fed by several small creeks — Piney Branch, Pinehurst Branch, Broad Branch, Soapstone Branch, and Luzon Branch — and numerous storm sewers.
