They converge after about . The stream, which usually carries very little water, enters the (Silver Valley) in the forest district of Deidesheim. After it reaches the Neustadt suburb of Gimmeldingen in the Benjental valley. Here, it is joined by an unnamed right tributary. The tributary is only long, but carries much more water. Its origin is the Loosenbrunnen springs on the north flank of the 533-metre-high Weinbiet on the eastern edge of the Palatinate Forest. Between 1952 and 1988, water from the spring was pumped up and used as drinking water in the local bar of Weinbiethaus.
