With salmon on the California coast disappearing, I wonder how many billions of dollars will be spent on hatcheries, habitat restoration, fish ladders and even trucks in an attempt to save the species. I also wonder how long government will rely on these failing approaches until confronting the obvious: the dam in Yosemite's Hetch Hetchy Valley must come down if salmon are to thrive again in the Sacramento-San Joaquin Delta.
