Bad decision on the part of the court.  If indeed the treaties speak to providing salmon fishing rights, a better solution to the culvert issue would be to provide equivalent fishing opportunity off reservations or wherever where salmon are present.  For a court to wave its hand and commit many many millions of dollars of taxpayer money to be spent is irresponsible.  When the principles enunciated by the court are applied to hydropower dams, say hello to massive global warming emissions from fossil fuels brought on line to replace the marvelous hydropower.
