The response was excellent in resolving both some rough spots in the original proposal and clarifying for the ISRP our misconceptions. They clarify that the project is not nearing termination, but intend for it to provide enumeration of adult summer Chinook in the Secesh River over the long-term. They explained the pilot project the ISRP referred to, and noted it was being completed with collections in 2006. They provided a succinct summary of the challenges of enumerating adult salmon using redd counts and discussed a timeframe to establish the precision and accuracy of estimates using DIDSON technology. The sponsors also clarified the methods they use to validate estimates using DIDSON, that hatchery and natural spawners and spawner ages are determined from carcass surveys, not from the DIDSON technology. Finally they clarified the status of video counts at Lake Creek, and the relationship between monitoring Lake Creek, Secesh River, and their roles as reference streams for Snake River spring and summer Chinook abundance and productivity. The roles of Lake Creek and Secesh monitoring provide good justification for continuation of the project.
