The refuge is not far from four dams on the lower Klamath River that could soon be demolished in the largest dam demolition project in U.S. history. The proposal to remove the dams on California's second-largest river to benefit threatened salmon has sharpened a decades-old dispute over who has the biggest claim to the river's life-giving waters.
