Section 4. Purpose and methods

Specific measureable objectives
The project objective is to reestablish a Teanaway River spring chinook run of up to 4,000 adults, which was the estimated run size before 1910. The planned Teanaway spring chinook acclimation facility would help accelerate achievement of this goal. Specifically, the project would remove the major transportation obstacle for spring chinook, and increase the quantity and quality of juvenile spring chinook and summer steelhead rearing habitat. The sub-objective of the project is to increase flows in the lower Teanaway River by up to 20 cubic feet per second.

Critical uncertainties
Two risks have been identified, however neither is thought to be significant.. The first risk is that we will not be able to entice enough water right holders to participate in the program to sufficiently improve flows. Given the interest already shown by water right holders, it does not appear that this risk will materialize. The second risk is that fish populations will respond neither to the increased rearing habitat nor the improved migration flows. This risk too is thought to be remote as experience has shown that fish are sufficiently opportunistic to attempt to exploit any available suitable habitat. In 1996, in spite of a lower than average spring chinook escapement, three spring chinook redds were constructed in the Teanaway. higher than average flows in 1996 made this unusual event possible.

Biological need
The Teanaway River was once a significant production area for Yakima spring chinook, steelhead and coho salmon. Low summer and fall flows in the lower mainstem block access to good spawning and rearing habitat upstream from the irrigated area, and render rearing habitat within the affected reach essentially useless. The Yakima Fisheries Project objective of increased natural production of spring chinook will be less difficult to meet when obstacles to utilization of spawning and rearing habitat are removed. Moreover, irrigation withdrawals significantly reduce summer rearing habitat conditions in the lower ten miles of the river. The proposed measures will substantially increase habitat connectivity in the upper Yakima river basin.

Alternative approaches
The Yakama Indian Nation could assert that its reserved water rights for instream lows supersede all state issued rights. If that effort were successful, diversions occurring pursuant to state issued rights would be ceased, thereby increasing stream flows by a greater amount than the subject proposal. However, it would take years and enormous litigation costs to get that matter resolved. Other legal, and equally dubious and expensive approaches are also possible. The subject proposal was selected as it offers swiftest and most probable means of achieving the desired flow improvement.

The project consists of implementing several different approaches to water conservation. Funds will be used to buy land with associated water rights, buy water rights, and pressurize and/or pipe existing inefficient gravity delivery systems. Few of the landowners contacted are willing to sell their land at the present time. Several land owners are willing to sell their water rights, however and negotiations are under way with them currently. One of the projects identified involves constructing a pumping plant at river mile 1.1 to replace an existing gravity diversion (approximately 10 cfs) and cal at river mile 4. That project will elimite leakage losses and leave the saved water in stream for an additional 3 miles. Other similar projects are also being developed.

Section 6. Outcomes, monitoring and evaluation


Expected performance of target population or quality change in land area affected
We expect a return of up to 4,000 adult spring chinook, including the contribution from the Teanaway acclimation site. The flow acquisition program is expected to yield up to 20 cfs in stream flow improvement. The project will also end the practice of annual in-channel dozer work.

Present utilization and convservation potential of target population or area
Spring chinook currently use the Teanaway River only in better water years. The Teanaway currently contributes insignificantly to Yakima River Basin spring chinook production.

Assumed historic status of utilization and conservation potential
It is believed that the Teanaway produced at least 4,000 spring chinook as well as several thousand coho and steelhead prior to European settlement.

Long term expected utilization and conservation potential for target population or habitat
4,000 spring chinook. management objectives for steelhead and coho have not been developed.

Indirect biological or environmental changes
The project will contribute toward a healthier benthos and aquatic community. It should also help restore nearer normal surface and ground water pathways.

Physical products
Flows in the lower 10 miles of the Teanaway River will be improved by up to 20 cfs over existing conditions.

Environmental attributes affected by the project
Water quality and quantity will both improve. Water temperatures currently exceed 22 C during the summer months. Flow improvement s are expected to lower summer temperatures to less than 19 C.

Changes assumed or expected for affected environmental attributes
Flow improvements are expected to be immediate. Ecosystem-level recovery to a new state of dymic equilibrium will take much longer. Macroinvertebrate populations should recover significantly within three to four years and should expand further in response to increasing salmon carcass availability. Fish habitat will increase immediately and productivity levels will follow recovery of lower trophic levels.

Measure of attribute changes
Flow increase of up to 20 cfs by the end of the 1999 irrigation season.

Assessment of effects on project outcomes of critical uncertainty
Spring chinook smolt production will be monitored at the Chandler juvenile trap. Spawner surveys will track adult escapements into the Teanaway.

Information products
The project will result in the dedication, through the state Trust Water Rights Program, certificated instream flow rights of up to 20 cfs. Project efficacy will be indirectly determined through various sub-tasks of the YFP.

It will be possible to measure flow increases resulting from the project. The more difficult measures of success will be measured indirectly. Spawner surveys will reveal changes in spawner abundance in the Teanaway, however, it would not be possible to establish a direct correlation between the project and increased fish production. Similarly, smolt production will be monitored at the Chandler juvenile facility, but it would extremely difficult to tease out the contribution of the Teanaway to the total. However, if the multiple habitat projects implemented in the Yakima Basin fail to yield detectable increases in smolt production and adult escapements, then we will be forced to rethink out habitat management paradigm.

Provisions to monitor population status or habitat quality
The Chandler juvenile trap and spawner surveys will provide adequate biological monitoring. Stream flow measurements and diversion metering will monitor water use and flow improvements.

Data analysis and evaluation
Smolt monitoring and spawner surveys are presented in annual reports prepared by YIN fisheries staff.

Information feed back to management decisions
If sufficient flow is not provided to allow adult migration in the Teanaway, then additional measures will required or the acclimation may have to be abandoned. If the flow improvements do not contribute to increased spawner escapements then other habitat restoration tools will have to be implemented, or the Teanaway may have to be dropped from our restoration candidate site list.

Critical uncertainties affecting project's outcomes
There are a myriad of factors affecting the number of salmon entering the Yakima River Basin. Identifying and gaining a better understanding of the relative importance of all contributing factors would help predict project outcomes.

The project will increase stream flows. This and other proposed projects should increase spring chinook production in the Yakima River Basin. The subject project further embodies one of the significant challenges confronting salmon managers in the Columbia Basin; reconciling conflict between instream and out of stream water uses. If the project simply clears that hurdle, it will at many scales be successful.

Incorporating new information regarding uncertainties
If the irrigator's demands get unreasoble then the project will be termited.

Increasing public awareness of F&W activities
The project has already received considerable attention in the local press. This is likely to continue.
