Industrial and agricultural pollution and toxic contamination, dams that block fish migration and access to spawning habitat—the decline of salmon, steelhead, sturgeon, and lamprey in the Columbia River is has many causes. To restore the river and the life that depends upon it, the Yakama Nation Fisheries is employing many and varied strategies, simultaneously. In some areas, habitat recovery is the key; in others, supplementation of salmon runs may need to be the driver.
