These creeks and streams are for natural runoff. If impede, you`re simply asking for trouble once you get that big gulley washer that will inevidibly come upon completion of this illadvised project.
Rocks. Don't barrier anything up - it could destroy the innate habitat and nobody wants to do that! Take some long walks/hikes at different streams surrounded by the area to see how the inborn waterfalls are made. You'll find that it's mostly rocks. Just variety sure to leave adequate of the creek open and flowing intrinsically to keep the habitat alive.
