The McCloud river is the point of origin for many of the world's rainbow trout populations. Despite the California gold rush, and thanks to the inaccessability of the valley, the river remained almost untouched since before the arrival of Europeans in the West. That is, until the river was dammed in 1945, wiping out the river's chinook and steelhead runs. But the trout remained. Then in 1965 another dam wiped out the bull-trout populations. Despite this, there are still unique populations of trout further upstream. Now the river is threatened once again by a proposal by Nestle to extract water for bottling, and by the proposal to raise the Shasta dam. When is enough, enough?
