Washington and Oregon have taken a similar view. At one time it was 'A good idea.' But in retrospect the dam no longer is. Pull it out!
One the entire Rogue River system, and all feeder rivers, there are only two left. And these are genuinely needed for flood control purposes. Below Wm. Jess you have 157 miles of free flowing river.
Many of the smaller dams on the Kalamath are next on the block for removal. Power company folks are at 're-license' time and installing fish ladders is just not financially realistic. Cost (give or take
) as much to install the ladders as it would to just pull the things out.
Betting is 'they go.'
