At the November 27, 2007 request of NOAA Fisheries, the ISAB reviewed the Interior Columbia River Technical Recovery Team’s (ICTRT) November 2007 technical review drafts of "Assessing the Impact of Environmental Conditions and Hydropower on Population Productivity for Interior Columbia River Stream-type Chinook and Steelhead Populations" and "Required Survival Rate Changes to Meet Technical Recovery Team Abundance and Productivity Viability Criteria for Interior Columbia River Basin Salmon and Steelhead Populations."

Generally, the ISAB finds the models to be scientifically sound and appropriately parameterized. However, the ISAB offers some suggestions on improving the analyses and the presentation of the analyses.
