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 addresses a reasonable question, but without an adequate description of methods. It is unclear from the proposal whether information from other dams on temperature control intake structures already exists to answer this question (it does). No explanation or itemization of the $10k budget is provided. The proposal is to consider the costs and potential biological benefit of installing a temperature control intake structure at Brownlee Dam. It then cites the Lower Snake and Salmon Subbasin Plans to indicate that water temperature is a limiting factor. It also cites a number of strategies for terrestrial species, which are of dubious relevance to the proposed work. The proposal has a single objective to investigate the biological and economic attributes of a temperature control structure at Brownlee Dam. The objective is reasonably explained, but without documentation of statements about the effect of irrigation withdrawals on temperatures in downstream reservoirs. Work elements describe a number of steps to acquire data on temperature and temperature control structures at other dams. The analysis tasks are described in more detail than in any other of this group of proposals, but details of analytical methods are missing.

State/province recommendation: MS: Do Not Fund

Comment: The USACE evaluated discharges from Brownlee, as well as previous Battelle studies. This issue is being addressed through FERC relicensing.
