Available in PDF, EPUB and Kindle. Book excerpt: Program RealTime provided tracking and forecasting of the 1998 inseason outmigration via the internet for stocks of wild PIT-tagged spring/summer chinook. These stocks were from eight release sites above Lower Granite dam, including Bear Valley Creek, Catherine Creek, Elk Creek, Lake Creek, Imnaha River, Minam River, South Fork Salmon River, and Secesh River. Forecasts were also provided for a stock of hatchery-reared PIT-tagged summer-run sockeye from Redfish Lake and for the runs-at-large of Snake River wild yearling and subyearling chinook salmon, and steelhead. The 1998 Program RealTime performance was comparable to its performance in previous years for the whole-season evaluations for every stock tracked. Relative to 1997, performance improved for the yearling chinook run-at-large, and for predictions for last-half of the season for every other stock. Performance compared poorly with 1997 predictions for the first half of the runs of PIT-tagged yearling spring/summer chinook stocks and the run-at-large of fall subyearling chinook, and was slightly worse for the first half of the Redfish Lake sockeye run and the steelhead run-at-large. Poor first-half performance was likely due to the unusually large (and in some cases short) outmigrations in 1998. Utilization in 1998 of a different method of adjusting smolt counts at Lower Granite Dam compared to previous years produced slightly better first-half performance than pre-1998 adjustments would have, but slightly worse last-half performance, for all the PIT-tagged stocks, prompting a return to the pre-1998 adjustment formula for the 1999 outmigration. An Army Corp of Engineers (ACOE) experiment during April and May of 1998 involving the installation of two new components to existing structures at Lower Granite Dam did not appear to affect RealTime performance. A comparison of run-timing predictions based on FPC passage indices and Battelle hydroacoustic counts showed the two independent data sources produced very similar results, for the wild steelhead and yearling chinook runs-at-large. Due to the less than desirable first half performance in 1998, a refinement in the calibration process for Program RealTime will be conducted in the future.

Book excerpt: Since the 1994 outmigration, program RealTime has been applied to provide in-season predictions of smolt outmigration timing for individual and aggregates of listed threatened and endangered Snake River salmon stocks. Results from the 1997 smolt outmigrations of wild Snake River yearling and subyearling chinook show prediction of run-timing can be accurately forecasted. The number of release sites meeting previous years criteria for RealTime forecasts dropped to five for the wild spring/summer chinook parr PIT-tagged in 1996: Catherine Creek, Imnaha, Lostine, Minam and South Fork Salmon Rivers. An experiment in lessening previous RealTime requirements for forecasting a outmigration in progress added three release sites of chinook: Lake Creek, Secesh and South Fork Wenaha Rivers; and one release of age 1+ sockeye at Redfish Lake. Passage indices provided by the Fish Passage Center for Lower Granite Dam were monitored for the wild subyearling chinook outmigration. Investigation continued into basing predictions on historical years with similar flows as a way to improve forecasting performance for the wild subyearling outmigration. Program RealTime's output is a series of estimated percentages of the status of the smolt outmigration throughout the season. To compare the performance the program from year to year, or to compare various assumptions used set up the forecasting, the mean absolute deviance (MAD) of the daily predicted outmigration-proportion from the actual outmigration-proportion is calculated post-season. Furthermore, these MAD's are considered for three periods of the season: the first 50% of the season, the second 50%, and the entire season.

Available in PDF, EPUB and Kindle. Book excerpt: Program RealTime provided monitoring and forecasting of the 2003 inseason outmigrations via the internet for 33 PIT-tagged stocks of wild ESU chinook [sic] salmon and steelhead to Lower Granite and/or McNary dams, two PIT-tagged hatchery-reared ESU of sockeye salmon to Lower Granite Dam, and 15 passage-indexed runs-at-large, five each to Rock Island, McNary, and John Day Dams. All of the 23 stocks of wild yearling chinook salmon which were captured, PIT-tagged, and released at sites above Lower Granite Dam in 2002, have been monitored at least once before the 2003 migration. These stocks originate in drainages of the Salmon, Grande Ronde and Clearwater Rivers, all tributaries to the Snake River, and are subsequently detected to the tag identification and monitored at Lower Granite Dam. In a continuation from the previous two years, seven wild PIT-tagged runs-at-large of Snake or Upper Columbia River ESU salmon and steelhead were monitored at McNary Dam. Two wild PIT-tagged runs-at-large were monitored at Lower Granite Dam, the yearling and subyearling chinook salmon and the steelhead trout runs. The hatchery-reared PIT-tagged sockeye salmon stocks outmigrating to Lower Granite Dam consisted of a stock from Alturas Lake and one from Redfish Lake. The passage-indexed stocks (stocks monitored by FPC passage indices) included combined wild and hatchery runs-at-large of subyearling and yearling chinook, coho, and sockeye salmon, and steelhead trout forecasted to Rock Island, McNary, and John Day Dams.

Available in PDF, EPUB and Kindle. Book excerpt: Program RealTime provided tracking and forecasting of the 2001 inseason outmigration via the internet for eighteen PIT-tagged stocks of wild salmon and steelhead to Lower Granite and/or McNary dams and eleven passage-indexed stocks to Rock Island, McNary, or John Day dams. Nine of the PIT-tagged stocks tracked this year were new to the project. Thirteen ESUs of wild subyearling and yearling chinook salmon and steelhead, and one ESU of hatchery-reared sockeye salmon were tracked and forecasted to Lower Granite Dam. Eight wild ESUs of subyearling and yearling chinook salmon, sockeye salmon and steelhead were tracked to McNary Dam for the first time this year. Wild PIT-tagged ESUs tracked to Lower Granite Dam included yearling spring/summer chinook salmon release-recovery stocks (from Bear Valley Creek, Catherine Creek, Herd Creek, Imnaha River, Johnson Creek, Lostine River, Minam River, South Fork Salmon River, Secesh River, and Valley Creek), PIT-tagged wild runs-at-large of yearling chinook salmon and steelhead, and a PIT-tagged stock of subyearling fall chinook salmon. The stock of hatchery-reared PIT-tagged summer-run sockeye salmon smolts outmigrating to Lower Granite Dam, consisted this year of a new stock of fish from Alturas Lake Creek, Redfish Lake Creek Trap and Sawtooth Trap. The passage-indexed stocks, counted using FPC passage indices, included combined wild- and hatchery-reared runs-at-large of subyearling and yearling chinook, coho, and sockeye salmon, and steelhead migrating to Rock Island and McNary dams, and, new this year, combined wild and hatchery subyearling chinook salmon to John Day Dam. Unusual run-timing and fish passage characteristics were observed in this low-flow, negligible-spill migration year. The period for the middle 80% of fish passage (i.e., progress from the 10th to the 90th percentiles) was unusually short for nine out of ten PIT-tagged yearling spring/summer chinook salmon stocks tracked to Lower Granite Dam. It was the shortest on record for seven of these ten stocks. The nine stocks recording unusually short middle 80% periods also recorded higher-than-average recovery percentages. However the opposite trend was observed for the PIT-tagged wild subyearling chinook salmon and hatchery sockeye salmon stocks whose middle 80% period of passage to Lower Granite Dam was average to above average. Recovery percentages for these two stocks were average, compared to historical recoveries. The performance results of Program RealTime to make accurate predictions of percentiles of fish passage at an index site were mixed this year. The release-recovery stocks of wild PIT-tagged spring/summer chinook salmon tracked to Lower Granite Dam were predicted less accurately than usual, on average, with two exceptions. One of these exceptions was a stock that had its best prediction (first-half, last-half, and season-wide) ever to occur. On average, however, performance was down for predicting these stocks. The RealTime Select composite season-wide MAD was 4.3%, larger than the historical average of 2.1%. Passage percentiles for PIT-tagged runs-at-large of wild Snake River yearling and subyearling chinook salmon and of wild steelhead outmigrating to Lower Granite Dam were predicted very well this year, their second year of inclusion in the project, with season-wide MADs of 3.6%, 4.7%, and 1.8% respectively. These results, too, were mixed with respect to comparison with last year's performance. The yearling chinook stock was predicted somewhat better last year (up from 1.7% last year to 3.6% this year) but the subyearling chinook salmon and steelhead stocks were predicted better this year than last, season-wide. The steelhead stock, in particular, was predicted much better this year than last year, down to 1.8% this year from 4.8% last year. The PIT-tagged runs-at-large of wild salmon and steelhead tracked to McNary Dam in 2001 for the first time, were also well-predicted. In particular, the Snake River stocks were well-predicted, with season-wide MADs of 4.7% for subyearling chinook salmon, 3.3% for yearling chinook salmon, and 1.4% for steelhead. All three Snake River stocks were better predicted at McNary Dam than they were at Lower Granite Dam. The Upper Columbia River PIT-tagged runs-at-large of wild subyearling chinook salmon and wild steelhead were not predicted with the remarkable accuracy of the Snake River stocks, but RealTime performance for these stocks was still good, with season-wide MADs of 7.9% and 4.9%, respectively. The results of RealTime predictions of FPC passage-indexed percentiles of combined wild and hatchery-reared salmonids to Rock Island and McNary dams were comparable to last year with respect to the large variability in performance. Like last year some runs were predicted very well while others were predicted very poorly. The stocks predicted best and worst last year were not necessarily the stocks predicted best and worst this year.

This book was released on 2005 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Umatilla Basin Natural Production Monitoring and Evaluation Project (UBNPMEP) is funded by Bonneville Power Administration (BPA) as directed by section 4(h) of the Pacific Northwest Electric Power Planning and Conservation Act of 1980 (P.L. 96-501). This project is in accordance with and pursuant to measures 4.2A, 4.3C.1, 7.1A.2, 7.1C.3, 7.1C.4 and 7.1D.2 of the Northwest Power Planning Council's (NPPC) Columbia River Basin Fish and Wildlife Program (NPPC 1994). Work was conducted by the Fisheries Program of the Confederated Tribes of the Umatilla Indian Reservation (CTUIR). UBNPMEP is coordinated with two ODFW research projects that also monitor and evaluate the success of the Umatilla Fisheries Restoration Plan. Our project deals with the natural production component of the plan, and the ODFW projects evaluate hatchery operations (project No. 19000500, Umatilla Hatchery M & E) and smolt outmigration (project No. 198902401, Evaluation of Juvenile Salmonid Outmigration and Survival in the Lower Umatilla River). Collectively these three projects comprehensively monitor and evaluate natural and hatchery salmonid production in the Umatilla River Basin. Table 1 outlines relationships with other BPA supported projects. The need for natural production monitoring has been identified in multiple planning documents including Wy-Kan-Ush-Mi Wa-Kish-Wit Volume I, 5b-13 (CRITFC 1996), the Umatilla Hatchery Master Plan (CTUIR & ODFW 1990), the Umatilla Basin Annual Operation Plan (ODFW and CTUIR 2004), the Umatilla Subbasin Summary (CTUIR & ODFW 2001), the Subbasin Plan (CTUIR & ODFW 2004), and the Comprehensive Research, Monitoring, and Evaluation Plan (Schwartz & Cameron Under Revision). Natural production monitoring and evaluation is also consistent with Section III, Basinwide Provisions, Strategy 9 of the 2000 Columbia River Basin Fish and Wildlife Program (NPPC 1994, NPPC 2004). The need for monitoring the natural production of salmonids in the Umatilla River Basin developed with the efforts to restore natural populations of spring and fall Chinook salmon, (Oncorhynchus tshawytsha) coho salmon and (O. kisutch) and enhance summer steelhead (O. mykiss). The need for restoration began with agricultural development in the early 1900's that extirpated salmon and reduced steelhead runs (BOR 1988). The most notable development was the construction and operation of Three-Mile Falls Dam (3MD) and other irrigation projects that dewatered the Umatilla River during salmon migrations. The Confederated Tribes of the Umatilla Indian Reservation (CTUIR) and the Oregon Department of Fish and Wildlife (ODFW) developed the Umatilla Hatchery Master Plan to restore the historical fisheries in the basin. The plan was completed in 1990 and included the following objectives: (1) Establish hatchery and natural runs of Chinook and coho salmon. (2) Enhance existing summer steelhead populations through a hatchery program. (3) Provide sustainable tribal and non-tribal harvest of salmon and steelhead. (4) Maintain the genetic characteristics of salmonids in the Umatilla River Basin. (5) Produce almost 48,000 adult returns to Three-Mile Falls Dam. The goals were reviewed in 1999 and were changed to 31,500 adult salmon and steelhead returns (Table 2). We conduct core long-term monitoring activities each year as well as two and three-year projects that address special needs for adaptive management. Examples of these projects include adult passage evaluations (Contor et al. 1995, Contor et al. 1996, Contor et al. 1997, Contor et al. 1998), genetic monitoring (Currens & Schreck 1995, Narum et al. 2004), and habitat assessment surveys (Contor et al. 1995, Contor et al. 1996, Contor et al. 1997, Contor et al. 1998). Our project goal is to provide quality information to managers and researchers working to restore anadromous salmonids to the Umatilla River Basin. This is the only project that monitors the restoration of naturally producing salmon and steelhead in the basin.
