In its upper reaches, on West Mountain/Bald Mountain, the stream has a gradient of approximately 400 feet (120 m) per mile.

However, in the relatively flat Keyser Valley, its gradient decreases to a mere 40 feet (12 m) per mile.

[1] A reach of it was removed by strip mining in the 1940s, but a rock-lined channel was constructed for the stream in the 1970s.
