Bonneville Power Administration (BPA) is proposing to fund the replacement of an existing ten-year-old seasonal fish weir with a permanent weir designed to operate safely over a range of flows. A weir is a fence or other structure placed across the creek to block passage for the purpose of catching and retaining fish. The weir will be used to monitor federally-listed Snake River steelhead and for the collection of spring Chinook salmon adults to support on-going supplementation programs in the watershed. Due to icing in the winter and high flows in the spring, the existing seasonal weir cannot be safely deployed during the typical adult steelhead migration period. After construction, the Nez Perce tribe would operate and maintain the weir.
Lolo Creek has been preliminarily determined to be suitable for Congressional designation into the Wild and Scenic (W&S) River system, and is considered one of the best whitewater kayaking runs in Idaho. As such, the proposed permanent weir would be designed to maintain the free-flowing nature of Lolo Creek, and the site would be developed to accommodate safe use of the site by kayakers.
Both BPA and Bureau of Land Management cannot proceed with a final decision until a biological opinion is issued from National Marine Fisheries Service. The biological opinion is tied to the Steelhead Hatchery Genetic Management Plan (HGMP) which will not be completed until early 2015. This project shall be in abeyance until the Steelhead HGMP is issued.
The public comment period is now closed. BPA accepted public comments about construction of the permanent weir through March 1, 2013. BPA will post comments received on the Lolo Creek Permanent Weir Fish Trapping Facility comments page.
