Description

The Swift No. 1 Hydroelectric Project is part of the Lewis River Hydroelectric Development located in southwest Washington State. It is owned and operated by PacifiCorp Energy. In 2008 the Federal Energy Regulatory Commission issued a new project operating license that called for the construction and operation of a Floating Surface Collector (FSC) in Swift Reservoir to collect then truck transport downstream migrating fish. Operation of the FSC began December 26, 2012. Several operating challenges were immediately apparent including small debris loads, low reservoir elevation and wind damage to the associated fish exclusion netting. PacifiCorp Energy fish passage staff is working closely with design and project engineers to resolve these issues and have already made several modifications and improvements to the intended design. This presentation will include a lessons learned –so far segment in conjunction with a separate presentation highlighting the engineering, design and construction aspects of the Swift FSC.
