Pettit Lake Creek Weir Construction (DOE/EA - 2140)
Blaine County, Idaho
Bonneville Power Administration (BPA) is proposing to fund the Shoshone-Bannock Tribes to construct a new weir on Pettit Lake Creek at the site of an existing weir that is undersized for the flows regularly encountered.  The weir would utilize current technology for capture of both in-migrating Snake River sockeye adults and out-migrating Snake River sockeye juveniles and be designed according to National Marine Fisheries Service criteria for this type of structure. It would also repair a wash-out around the weir’s right bank abutment caused by the current weir’s inadequate design. Construction would require building a 150-foot-long temporary access spur to the site, and temporary use of a previously-disturbed site over 300 feet from Pettit Lake Creek for staging and equipment storage and service.
The Sawtooth National Recreation Area (SNRA) is the lead agency and BPA is a cooperating agency for the project’s environmental review. To understand the potential environmental impacts of this proposal, the SNRA, in cooperation with BPA, will prepare an environmental assessment (EA) following the procedures of the National Environmental Policy Act (NEPA). The EA will analyze the Pettit Lake Creek Weir construction proposal, as well as a no-action alternative in which BPA funding would not be provided for construction, and the current structure would remain in use. The EA will describe anticipated impacts to natural and human resources and will identify mitigation measures to help avoid or minimize impacts. During this process, the SNRA and BPA has worked with landowners, tribes, federal, state and local agencies, and interest groups.
The proposed schedule for the environmental review is as follows:
Scoping comment period                                          February 19, 2020 - March 20, 2020
Draft EA comment period                                         Spring 2020
Final EA                                                                    Summer 2020
Finding of No Significant Impact (if warranted)        Summer 2020
If decision to build, construction start                       Summer/Fall 2020
The USFS requested public scoping comments on February 19, 2020. The comment period closed on March 20, 2020. For more information or to comment, visit the SNRA project website at:
