- _Cadillac Desert_, good reference. But the current thinking here is
- that for the Idaho sockeye salmon (Columbia river), the biggest problem
- might not be the return up the fish ladders, but that the young salmon don't
- migrate downstream through the enormous slack waters of the impoundments.
- That is, the downstream mortality is more serious. It also has the
- convenient property that it can be solved by radically decreasing
- the amount of stored water (thus increasing the flow rate). Some
- local acquaintances are seriously pursuing the concept of building
- tunnels/culverts in the reservoirs to flush the little ones downstream.
-
- ObSingles: What would you do if you were the last member of your
- sex returning to the traditional spawning grounds. And how
- important is 'attractive'? Talk about performance anxiety, heh!
