Every major river that drains into the Central Valley was dammed at low elevations, creating a "terminal rim" that, among other devastating consequences, excluded salmon from 90 percent of their spawning habitat. As a result, Central Valley salmon runs that historically were four to five million strong have been reduced to a few thousand primarily hatchery-raised fish, clear indication that one of the world's great ecosystems is on the verge of collapse. These dams have disconnected our ocean from our mountains, severing a life-cycle that has balanced the ecology of our freshwater, saltwater, and terrestrial environments. The fate of salmon and the fate of our living rivers is now very much in our hands.
