An artificial stream bed could be used made of concrete. A very natural
stream bed anologus to a stream flowing over hard pan. It would seem to at
least be an idea to help fish swim up the miles of slow gentle steps. Of
course dams do more than just isolate the ocean from the land and interfere
with nutrient transportation. they also drown moving stream habitat that
often leave huge deep areas of what is really dead bottom in fresh water.
