Duke also did work on a minor tributary of the Raritan which later took the name Duke's Brook. Here he instructed his architects to place dams at several locations along the stream to create small lakes behind them. This is no doubt what was intended by the dam that created the "Roycefield Falls" at the bridge near the intersection of Roycefield Road and Duke's Parkway.
