Initial testing of the new bubbler at Lower Monumental Dam. This technology replaces an older, costlier, and labor-intensive "deep water chimney" system that drew cold water from below the thermocline to cool the fish ladders. The new, highly cost-effective bubbler system encourages salmon and other cold-water species to safely use the ladders during migration.
