PacifiCorp has installed two floating booms on Swift Reservoir to keep debris out of its $60 million fish collector.Boaters at Swift now have to go through the narrow boom passage near Swift Forest Camp to access most of the 4,500-acre reservoir.The other boom is on the bay where Swift Creek flows into the reservoir north of Devil’s Backbone.PacifiCorp began operation of the fish collector this winter. It is attached to Swift Dam. It has a flow to attract downstream-migrating salmon and steelhead produced in the upper watershed of the North Fork of the Lewis River.Solar lights are on the booms. PacifiCorp says maximum depth clearance is 10 feet.A deepwater net is in front of the fish collector and is visible as a floating orange line on the water’s surface. The net guides young fish to the collector. Boaters are urged to stay 200 feet away from the orange line.
