Management implications

Specific measureable objectives
The specific measurable objective of this project is the development of technology that will enable fishery managers to precisely, accurately, and relatively inexpensively estimate salmon escapement from natural and artificial origins. This technology will directly benefit stocks from the Klickitat Basin as well as serve stocks from other basins from this project's innovative approach.

Testable hypothesis
Time-lapse videography incorporated in a temporary weir on a tributary of the Klickitat River can be used to estimate salmon escapement.

Video-based escapement estimates will be more accurate and less expensive than methods now being used.

Underlying assumptions or critical constraints
Extreme water conditions (30 year flood event during fish passage period) may limit project success.

Methods
A temporary picket fence type weir will be located in a suitable location on a tributary to the Klickitat River. The fence will guide migrating fish through a funnel shaped opening into a count slot. A video camera will be operated within the count slot and record passing fish. Fish will have free access to move downstream through the count slot as well as upstream. The count slot width will be similar in size to those located at mainstem dams. The counting station will be removed after the fish migration period is complete.
Videotapes of fish passage will be reviewed and fish enumerated. Comparisons will be made between these escapement estimates and those made from redd counts. A cost comparison of the two methods will also be made.
A videotape editing system, that we have previously developed, will be modified to operate in digital format. This system will be used to reduce the effort required to evaluate recorded videotape records. The precision of this system will be compared with counts from source tapes. A cost analysis for this system will also be made.

Biological need
The current methods used to estimate salmon escapement are not as accurate as management requires. Previous studies have shown that direct count methods are much more accurate and reliable. In addition, they are quite expensive to obtain.
Video-based fish counting studies have been shown to be very effective methods for estimating escapement. These methods are used extensively in other basins, but have not been fully utilized in the Columbia Basin.

Critical uncertainties
None

Summary of expected outcome
A highly accurate salmon escapement estimation system will be developed and deployed in a critically important production area of the Columbia Basin. Major cost savings will be achieved. This system and it's operation will have no negative impacts on the fish stocks or the stream. This system will be used as a model for monitoring throughout the Columbia Basin. The digital editing system will be an integral part of the operation of this fish counting system.

Dependencies/opportunities for cooperation

Risks

Monitoring activity
Escapement estimates derived from alternative methods will be compared with direct video-based counts.

Section 3. Budget

Data shown are the total of expense and capital obligations by fiscal year. Obligations for any given year may not equal actual expenditures or accruals within the year, due to carryover, pre-funding, capitalization and difference between operating year and BPA fiscal year.
