The undoing of PNW salmon runs has been attributed to unsustainable abuses in the dreaded 4 H's....
The only dam I know of in the Kenai system sits at the top of Cooper Creek.
Now I understand that HEA (Homer Electric? if I remember correctly) has 4 new hydro projects in the pipeline. Grant, Ptarmigan, Falls and Crescent. Permits were issued in October.
Cutting edge salmon scientists also cite a 5th H that society has conveniently ignored in the PNW salmon crisis (as well as the collapse of salmon on the East Coast and Europe).... and that is History. Why would we risk dooming these fish to the mistakes of the past?
