This is really about the only option other than abandoning the road guys - the highway can't be re-routed because there is a deep rotational slide all the way up the side of the mountain. Either no 101 or this has to work. The way they have been protecting the highway, with rock, has captured the thalweg and prevented the river from migrating across it's floodplain, concentrating energy in this one area and continually undermining the rock bulkhead, while pretty much trashing rearing habitat - the hole might hold adults but it's a lousy place for juveniles. This is a gamble to be sure, but I've looked at the plans and what they have designed to anchor the log jams is beyond belief and beyond the ability of any amount of water to move. And wood, unlike rock, provides rearing habitat, so this will be far better for fish than the present situation. It's no sure thing that this will make the river do what they hope it will, but there are pretty much no other feasible alternatives, so I wish them luck, and drought in the mean time
