Restoration of instream flows in the Teanaway River through the lease or purchase of land and water rights.

Project development phase Implementation
8812000: Yakima Natural Production and Enhancement: The proposed would increase the effectiveness of the Yakima Fisheries Project by providing additional passage and rearing habitat for spring chinook and summer steelhead. A spring chinook acclimation facility is already planned for the Teanaway River.

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.
Underlying assumptions or critical constraints
Irrigation diversions dry up the Teanaway River in the late summer and early fall. We plan to lease or purchase irrigated land and/or water rights to provide reliable instream flows during this period. This in turn would provide transportation and rearing habitat for spring chinook and summer steelhead. The Teanaway River drainage contains considerable unused spawning and rearing habitat for anadromous fish. Fall-spawning anadromous fish currently have little or no access to this habitat.
Brief schedule of activities
1997: Map irrigation systems and irrigated lands. Begin appraisal process, and begin acquiring land and water rights.
1998: Conclude acquisition process.
The Teanaway River was once a significant production area for Yakima spring chinook, steelhead and coho. Low summer and fall flows in the lower mainstem block access to good spawning and rearing habitat upstream from the irrigated area. 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.
The uncertainty regarding the spring chinook population response to increased freshwater habitat is relatively small in this case. There are already indications of density dependence in the survival rate of Yakima spring chinook to the smolt stage. Furthermore, planned acclimation and release of spring chinook in the Teanaway River is expected to provide more returning adult fish to utilize newly-accessible habitat.
Summary of expected outcome
We expect a return of up to 4,000 adult spring chinook, including the contribution from the Teanaway acclimation site.
Dependencies/opportunities for cooperation
We anticipate no NEPA/SEPA requirements, or any permits beyond what is normally required for land purchase or lease.
The intensive monitoring efforts under the Yakima Fisheries Project will assess spring chinook population size and productivity in the Teanaway River, and interactions with other species.
