This information was not provided on the original proposals, but was generated during the review process.
The upper Cowlitz watershed apparently shows excellent potential for the Anadromous Fish Reintroduction Program. This proposal would provide an assessment tool for development of an improved surface collection design and for assessment of production from the upper basin. The combination of the collection system and the need to transport all adults into the upper basin for spawning provides a unique opportunity to examine salmon restoration and the productivity of "hatchery" based brood stock allowed to spawn naturally in a barren habitat (Section 9c in proposal). The system for study would be essentially "closed" (no input or output without monitoring), provides highly productive natural habitat, and would have good evaluation capability with this PIT development at the Fish Facility.
The following comment also applies to project 31017 and a joint response is likely warranted. A response is requested on how the Anadromous Fish Reintroduction Program is being evaluated. This
project could potentially be very worthwhile but its value needs to be assessed within the context of the evaluation, what are the objectives of the evaluation, what are the results of the evaluation to date? The ISRP would strongly recommend the development of an experimental design to utilize this unique opportunity. Further, the PIT equipment would provide the tool for assessing collector designs but what is being done to re-design this system for improved efficiency?
BPA has already invested heavily in the Cowlitz watershed by building the Fish Facility ($22 million) but this proposal has good cost sharing and local support. There is an opportunity for exciting and informative research programs concerning salmon restoration, role of nutrients in the ecosystem, and hatchery versus wild comparisons in the upper Cowlitz watershed.
