Project Summary

Project 2007-077-00 - Hemlock Dam Removal
Project Number:
Hemlock Dam Removal
Hemlock Dam is scheduled for removal during the summer of 2008. Removal of the dam will improve migration, water quality, and habitat for Lower Columbia River steelhead, and will restore important watershed processes in Trout Creek, a tributary to the Wind River in southwest Washington. This contract provides support to acquire engineering services for designing the dam removal and construction of a channel in the area occupied by the reservoir. The intent is to award an A&E contract during the summer of 2007, and to keep the A&E consultant on contract through the construction period, which is scheduled to occur in summer of 2008. For that reason, this contract will exceed one year in length.

Due largely to delays in receiving permits, implementation of the dam removal was rescheduled for summer 2009. The reschedule of funds was reviewed and approved by the BOG. This contract is changed only insofar as it is necessary to revise the estimated dates for completion of work. There is no additional funds requested under this CR.

Council Recommendation

Assessment Number: 2007-077-00-NPCC-20090924
Project: 2007-077-00 - Hemlock Dam Removal
Review: FY07-09 Solicitation Review
Approved Date: 10/23/2006
Recommendation: Fund
Comments: ISRP fundable qualified: produce an updated streambank stablization plan prior to dam removal. If BPA cost share policy with the USFS identifies a contribution from the USFS, $100,000 total of the recommended budget savings should be moved to project # 200721500 to conduct steelhead population estimates. Any remaining funds from Hemlock Dam removal could be moved to project # 199801900.

Final Round ISRP Rating: Meets Scientific Review Criteria (Qualified)
Final Round ISRP Comment:
This well-written proposal provides a clear description of what appears to be an important problem and excellent opportunity for substantial gain for fish, especially steelhead, by improving access to 15 mile of stream. The current fish ladder is inadequate. Dam removal would open up significant habitat that has received some extensive restoration such as side channel work. There is strong collaborative effort on this project, especially with USFS, and monitoring and evaluation would be done by WDFW and UCD under separate projects.

The ISRP is not requesting a response but believes the project sponsors, Council, and BPA should consider the following points. A new 1/3 mile-long channel will be excavated through the accumulated sediments and stabilized prior to dam removal. Stabilizing the stream banks will not be an easy task. Although the proposal describes some methods to stabilize the banks, such as use of root wads and tree planting on the banks, reviewers expect a major element will be - or should be - soil bioengineering in nature. This "fundable" recommendation is qualified. If funded, the Council and/or BPA should require a more complete description and clarification of how the streambed and banks will be stabilized, and what variations in plan, longitudinal and cross-sectional profiles are envisaged. If requested, the ISRP would be willing to review the updated stabilization plan.
