The background section discusses different perspectives on the problem of Snake River juvenile salmon mortality and the question of improving survival. It contains excerpts from the Corps report "Lower Snake River Juvenile Salmon Migration Feasibility" to demonstrate that although dam breaching is identified by the Corps as a less preferable alternative to major system improvements, it may become a more realistic alternative if adaptive migration efforts are not successful. Some description of alternatives being considered by the Corps is presented. The intent of the proposal is to reduce economic effects on the ratepayers of Lower Snake River dam and reservoir removal. A summary list of major costs associated with these removals is included with a more detailed description of one (turbine modification) as an example of how costs might vary with different designs.

The single objective of this proposal is to expand the list of alternatives to be considered in a re-evaluation study, which would follow a failed "check-in.” It seeks to lower the economic costs of dam removal. The methods section describes some alternatives that the Corps did not consider which might be lower cost. It describes some explanatory information from the Corps as to why certain configurations would not be considered, then notes that this information should be kept from the public until after the competition to ensure fairness. The proposal does not indicate whether this information is already available in published form. The proposal states that entries will be judged on "economic viability" and "affordability," without explanation of how these are defined. A list of work elements provides a general description of how the contest will be conducted.
