Available in PDF, EPUB and Kindle. Book excerpt: Spring chinook salmon populations in the Imnaha and Grande Ronde rivers are listed as threatened under the Endangered Species Act (ESA) and are at high risk of extirpation. The Nez Perce Tribe, the Confederated Tribes of the Umatilla Indian Reservation, and Oregon Department of Fish and Wildlife, are co-managers of conservation/restoration programs for Imnaha and Grande Ronde spring chinook salmon that use hatchery supplementation and conventional and captive broodstock techniques. The immediate goal of these programs is to prevent extirpation and provide the potential for restoration once factors limiting production are addressed. These programs redirect production occurring under the Lower Snake River Compensation Plan (LSRCP) from mitigation to conservation and restoration. Both the Imnaha and Grande Ronde conservation/restoration programs are described in ESA Section 10 permit applications and the co-managers refer to the fish production from these programs as the Currently Permitted Program (CPP). Recently, co-managers have determined that it is impossible to produce the CPP at Lookingglass Hatchery, the LSRCP facility intended for production, and that without additional facilities, production must be cut from these conservation programs. Development of new facilities for these programs through the Columbia Basin Fish and Wildlife Program is considered a new production initiative by the Northwest Power Planning Council (NPPC) and requires a master plan. The master plan provides the NPPC, program proponents and others with the information they need to make sound decisions about whether the proposed facilities to restore salmon populations should move forward to design. This master plan describes alternatives considered to meet the facility needs of the CPP so the conservation program can be fully implemented. Co-managers considered three alternatives: modify Lookingglass Hatchery; use existing facilities elsewhere in the Basin; and use new facilities in conjunct ion with a modified Lookingglass Hatchery. Each alternative was evaluated based on criteria developed for rearing fish for a conservation program. After this review, the Nez Perce Tribe determined the only alternative that meets the needs of the program is the alternative to use new facilities in conjunction with a modified Lookingglass Hatchery. This is the Proposed Alternative. The Proposed Alternative would require: Construction of a new incubation and rearing facility in the Imnaha River and modifications of the existing Gumboot facility to accommodate the Imnaha component of the Lookingglass Hatchery production; Construction of a new incubation and rearing facility in the Lostine River to accommodate the Lostine component of the Lookingglass Hatchery production; and Modifications at Lookingglass Hatchery to accommodate the Upper Grande Ronde and Catherine Creek components of the Lookingglass Hatchery production. After an extensive screening process of potential sites, the Nez Perce Tribe proposes the Marks Ranch site on the Imnaha River and the Lundquist site on the Lostine River for new facilities. Conceptual design and cost estimates of the proposed facilities are contained in this master plan. The proposed facilities on the Imnaha and Lostine rivers would be managed in conjunction with the existing adult collection and juvenile acclimation/release facilities. Because this master plan has evolved into an endeavor undertaken primarily by the Nez Perce Tribe, the focus of the document is on actions within the Imnaha and Lostine watersheds where the Nez Perce Tribe have specific co-management responsibilities. Nevertheless, modifications at Lookingglass Hatchery could make it possible to provide a quality rearing environment for the remainder of the CPP. The Nez Perce Tribe will assist co-managers in further evaluating facility needs and providing other components of the NPPC master planning process to develop a solution for the entire CPP. Although the fish production for the conservation programs is already authorized and not at issue in this master plan, a detailed description of the fish culture program, historic and current management practices, and life history and biology of Imnaha and Lostine River spring chinook salmon is also provided in this master plan for background and supporting information.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For the second consecutive year, the Nez Perce Tribe, in conjunction with the Fish Passage Center, participated in the smolt monitoring program in the Imnaha River. A rotary screw trap was used to collect emigrating wild and hatchery chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) smolts from February 6 to June 20, 1995. We PIT tagged and released 421 wild chinook salmon smolts, 747 hatchery chinook salmon smolts (445 HxW and 302 HxH), 227 wild steelhead trout smolts and 1,296 hatchery steelhead trout smolts. Cumulative interrogation rates at mainstem Snake and Columbia River dams were 78.4% for wild chinook salmon, 58.9% for hatchery chinook salmon (HxW), 56.6% for hatchery chinook salmon (HxH), 76.2% for wild steelhead trout, and 69.2% for hatchery steelhead trout. Peak outmigration of NPT tagged wild Imnaha River chinook salmon smolts occurred from early to mid-May at Lower Granite, Little Goose, and Lower Monumental Dams. Median and 90% passage dates for wild chinook salmon smolts at Lower Granite Dam were May 1 and May 11, respectively. Continuous spill at Lower Granite Dam was initiated on May 3 and lasted for 51 days. The 90% passage date of wild chinook salmon smolts at Lower Granite Dam (May 11) preceded peak Snake River and Lower Granite (June 6) flows by 26 days. Although hatchery chinook salmon exhibited a shorter outmigration period through the Snake River than their wild counterparts, peak arrival for both groups occurred at approximately the same time. Median and 90% passage dates at Lower Granite Dam for other PIT tagged groups were: hatchery chinook salmon (NPT-HxW) - May 2 and May 13; hatchery chinook salmon (FPC-HxH) - May 8 and May 15; wild steelhead trout - May 2 and May 9; and hatchery steelhead trout (NPT and FPC) - May 31 and June 16. Hatchery steelhead trout displayed small peaks in arrival timing at Lower Granite and Little Goose Dams in mid-May to mid-June.

This book was released on 2002 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results of the Lower Snake River Compensation Plan Hatchery Evaluation Studies (LSRCP) and the Imnaha Smolt Monitoring Program (SMP) for the 1999 smolt migration from the Imnaha River, Oregon. These studies were designed and closely coordinated to provide information about juvenile natural and hatchery chinook salmon (Oncorhynchus tshawytscha) and steelhead (Oncorhynchus mykiss) biological characteristics, behavior and emigrant timing, survival, arrival timing and travel time to the Snake River dams and McNary Dam on the Columbia River. Data collected from these studies are shared with the Fish Passage Center (FPC). These data are essential to quantify smolt survival rates under the current passage conditions and to evaluate the future recovery strategies that seek to optimize smolt survival through the hydroelectric system. Information shared with the FPC assists with in-season shaping of flow and spill management requests in the Snake River reservoirs. The Bonneville Power Administration and the United States Fish and Wildlife Service contracted the Nez Perce Tribe (NPT) to monitor emigration timing and tag 21,200 emigrating natural and hatchery chinook salmon and steelhead smolts from the Imnaha River during the spring emigration period (March 1-June 15) with passive integrated transponder (PIT) tags. The completion of trapping in the spring of 1999 marked the eighth year of emigration studies on the Imnaha River and the sixth year of participating in the FPC smolt monitoring program. Monitoring and evaluation objectives were to: (1) Determine spring emigration timing of chinook salmon and steelhead smolts collected at the Imnaha River trap. (2) Evaluate effects of flow, temperature and other environmental factors on emigration timing. (3) Monitor the daily catch and biological characteristics of juvenile chinook salmon and steelhead smolts collected at the Imnaha River screw trap. (4) Determine emigration timing, travel time, and in-river survival of PIT tagged hatchery chinook salmon smolts released at the Imnaha River acclimation facility to the Imnaha River Trap. (5) Determine arrival timing, travel time and estimated survival of PIT tagged hatchery and natural chinook salmon and natural and hatchery steelhead smolts from the Imnaha River to Snake and Columbia river dams.
