The feds must breach four dams on the lower Snake River in order to honor treaty obligations to Indian tribes in the Northwest, according to a new report from a consultant to the Army Corps of Engineers. The corps is considering three options for restoring salmon and steelhead trout in the river and will make a recommendation on the best option early next year. According to economist Phil Meyer, author of the report, breaching the dams “would reverse an almost century-and-one-half trend to cumulatively strip the tribes of their valued and treaty-protected rights” to fish in their traditional areas.
