Want to be excited. Sounds great. One question though. Why would this river be any different than those on the OP that flow unimpeded from pristine habitat in a national park? Hatcheries and exploitation from the word "go" (ok, 5 yrs) will not bring back #100 kings, rainbows in the lower reaches, summer nor winter run.
Instead, leave the GD thing alone and maybe, just maybe, we'll have a model of what could be done on a grander scale throughout the region.
Want to believe, really do. Unfortunately, we've been there and done that. Just another river with emergency regs when escapement doesn't reach even a sham MSY minimal level.
