  • Tribal Pacific Lamprey Restoration Plan


    The Pacific lamprey provided an important source of food for the tribes of the Columbia River Basin. Once retuning to the Columbia River and its tributaries by the millions, approximately 48,000 returned to Bonneville Dam in 2011. To address this decline, the Columbia River treaty tribes created the most comprehensive restoration plan for Pacific lamprey that the Columbia Basin has seen.
