I just heard that from a bone dry fish ladder to watering it up, in an hour and forty minutes the first chinook passed through the modified fish ladder. A large pump puts water in the fish ladder, and at the crest the fish jump over a false weir as though moving up to the next step pool in the ladder, only instead they land in a water slide that takes them down to the lowered forebay on the upstream side of Wanapum Dam. So far, so good. The second ladder should come into service today, well before large numbers of fish begin showing up.
