In my youth I tossed boulders into the concrete bridge/tunnel that the crick flowed through, backing it up slightly. Someone, probably with the county, eventually disbursed those boulders. That 1ft fall had no feet of run because it came from the tunnel/bridge. I timed how long it took to fill a 5 gallon bucket and then multiplied the width to guestimate the flow. Very imprecise but not off by an order of magnitude.

I figure my micro hydro dream property probably lies somewhere on the North Santiam river.
