Stop in for a cup of coffee
At the utility I work for they build floating surface collectors at both dams, they simulate currents and the fish come in. They go in a "fish taxi" and are driven above the dams into the lake. Very tech advanced, even have a com room I work in sometimes. Anyhoo, they have re-established the salmon run on the lake, pretty good numbers of Sockeye now in July, great fishery actually.
