Final Council recommendation (Nov 2006)

Funding category: Expense

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


ISRP final recommendation: Not fundable


This is an inadequate proposal. It is quite generally written and is not persuasive as to why such flood control issues are not already known and routinely considered by the river operations system. No explanation or itemization of the $10k budget is provided. This proposal would prepare for the contingency of dam breaching by clarifying the differing perspectives on whether the Lower Snake River dams provide flood control benefits or risks. The background section contains much of the same information as in the other proposals from this sponsor, with a focus on the US Army Corps of Engineers report "Lower Snake River Juvenile Salmon Migration Feasibility." The rationale for the proposed work is stated as finding viable alternatives to Corps’ plans. The proposal rests on the assumption that this is an issue best clarified in advance of a decision about dam breaching so that political acceptability of options can be discerned. It also rests, as does the entire set, on the need to assess the categories of impacts, in which the Corps identifies that adaptive migration might be a preferred alternative to dam breaching. The single objective of this proposal is to "clarify and investigate" competing claims about flood control risks and benefits of the Lower Snake River dams. Work elements are inadequately described and incompletely referenced. The risk/benefit analysis is not described. The proposal does not describe the type of information the river operating system already routinely tracks and assesses with regard to flood control.

Comment: Flood control is a USACE responsibility and there was a very recent study out for public comment.
