Plans to raise water levels at Shasta Dam are sparking debate, with tribal members warning the change would cause spiritual harm. The proposal would increase water storage capacity, and state leaders say the additional storage is needed during drought years. But for the Redding Rancheria, which has members of the Winnemem Wintu Tribe, the issue goes beyond water. Tribal Chairman Jack Potter said the dam has already disrupted salmon runs and that raising water levels would submerge sacred areas that remain, including burial sites and places where they hold traditional ceremonies.
