200703300 - Monitor sub adult and adult bull trout passage through Lower Granite, Little Goose and Lower Monumental juvenile bypass facilities

Sponsor: US Fish & Wildlife Service (USFWS)

Budgets: FY07: $141,912 | FY08: $113,729 | FY09: $120,090

Short description: Enumerate bull trout passage through Lower Snake River dams' juvenile bypass systems. Evaluate as a potential source of take through the incidental barging of migratory bull trout. Determine most likely origin of bull trout utilizing these facilities.

Funding category: Expense

Recommended budgets: FY07: $0 | FY08: $0 | FY09: $0


ISRP final recommendation: Not fundable


In response to a request by the ISRP, the sponsors of the proposal provided summarized information (from a 2004 report by Battelle PNNL) of bull trout presence in fish ladders and juvenile bypass facilities at three lower Snake River dams. The small number of fish actually recorded and the very roughly expanded estimates based on a 0.4-100% sampling rates are not enough evidence to conclude that a significant problem exists for bull trout passing lower Snake River dams or that significant numbers of bull trout may be unintentionally transported down-river on barges. In addition, the proposal does not adequately demonstrate that the methods they plan to employ will be sufficient to estimate the parameters they identify in their tasks. They fail to show that the sampling scheme (sampling in the juvenile bypass systems) coupled with the planned PIT tagging is actually sufficient to estimate the number of bull trout and the proportion of bull trout that end up in smolt barges. The project sponsors are advised to conduct a focused demonstration or pilot study (within the Corp's AFEP Program) at one of the lower Snake River dams (i.e., Lower Granite Dam) to produce data indicating the potential significance of bull trout entrainment into smolt transportation barges.

State/province recommendation: MS: Core Program

Review group: MSRT

Recommended budgets: FY07: $116,412 | FY08: $116,412 | FY09: $116,412

Comment: There are several bull trout monitoring projects proposed here that provide good coverage of the basin. Other bull trout monitoring projects are proposed in the local subbasin processes. The MSRT would like to see a comprehensive picture of what bull trout monitoring is being funded throughout the basin to insure there is a common strategy for monitoring bull trout (consistent with the MSRT desire to see a coordinated plan for monitoring salmon and steelhead). Basic monitoring and evaluation for bull trout is a Core Program activity, the additional research activities in some of the bull trout projects are a lesser priority.
