1907 and expanded in the 1920s. Although it was not within the original 1890 bounds of the Park, Piney Branch Parkway is legally a part of Reservation 339 and was included in the 1991 boundaries of the Rock Creek Park Historic District." of a mile through a strip of forested parkland about 1,000 yards wide on the eastern side of Rock Creek. The watershed comprises 2,500 acres and is completely within the District of Columbia, making it the largest of all of the District’s tributaries. The large size of the watershed compared to the short surface stream length (0.75 miles) results from the extensive combined sewer and storm sewer systems that discharge to Piney Branch. The surface stream portion of the watershed is surrounded by predominantly forested parkland and comprises about five percent of the entire watershed. The rest of the watershed is primarily urban residential and some light commercial. Piney Branch is approximately 12 feet wide and has a depth of about four inches. In 1993, normal water flow was estimated at 1.8 cubic feet per second. Erosion was noted in the form of channel alteration, bottom scouring, and lack of vegetative cover. "
