In addition, those lower Snamke River dams provide substantial irrigation for the massive agricultural areas in northern Idaho and southwestern Washington. This water will have to be replaced, different crops will have to be grown there, or the land will have to removed from the agricultural pool altogether.

Hundreds of millions were spend building those dams, now hundreds of millions more are spent destroying them, plus building bridges over the river to replace the roads that presently traverese the top of the dams.

Of course thge salmon are important, too,  not only for environmental reasons, but economic ones as well. The salmon are also an important food source. There are no easy answers, but destroying the dams seems a drastic step, and once they are gone, there is no going back.
