"abstract": "We used Passive Integrated Transponder (PIT)-tagging and a series of instream PIT-tag\ninterrogation systems (PTIS) to investigate life-histories, populations, and efficacy of habitat\nrestoration actions for steelhead Oncorhynchus mykiss in the Wind River subbasin, WA. Our\ntagging focused on parr in headwater areas of the subbasin and our PTISs provide information on movement of these parr, which is primarily, but not exclusively downstream. The PTISs also\nprovide data on life-history aspects of other steelhead life-stages. The Wind River subbasin in\nsouthwest Washington State provides habitat for a population of wild Lower Columbia River\nsteelhead and is an excellent watershed for long-term studies of population dynamics and\nresponses to restoration of this wild population. Much data on steelhead population metrics have\nbeen gathered from the Wind River providing information on habitat restoration actions and\nongoing research into steelhead life histories. Additionally, the Wind River is an excellent\ncontrol watershed of an exclusivly wild steelhead population to which basins with hatchery\nprograms can compare. No hatchery steelhead have been planted in the Wind River subbasin\nsince 1994, and hatchery adults are estimated to be less than one percent of adults in any year\n(pers comm. Thomas Buehrens, Washington Department of Fish and Wildlife). Numerous\nrestoration actions have been implemented in the subbasin, including the removal of Hemlock\nDam on Trout Creek in 2009. Data from our study, and companion work by Washington\nDepartment of Fish and Wildlife (WDFW), will contribute to Bonneville Power Administration\u2019s\n(BPA) Research Monitoring and Evaluation (RM&E) Program Strategy of Fish Population\nStatus Monitoring (www.cbfish.org/ProgramStrategy.mvc/ViewProgramStrategySummary/1),\nspecifically the sub-strategies of: 1) Assessing the Status and Trends of Diversity of Natural\nOrigin Fish Populations and to uncertainties research regarding differing life histories of a wild\nsteelhead population, 2) Assessing the Status and Trend of Adult Natural Origin Fish\nPopulations, and 3) Monitoring and Evaluating the Effectiveness of Tributary Habitat Actions\nRelative to Environmental, Physical, or Biological Performance Objectives.\n\nDuring summer 2015, we sampled and PIT-tagged age-0 and age-1 steelhead parr in\nheadwater areas of the Wind River subbasin to characterize population traits and investigate\nvariable life-histories, including growth and parr movement downstream prior to smolting.\nThroughout the year, we maintained a series of instream PTISs to monitor movement of tagged\nsteelhead parr, smolts, and adults. Detections at the instream PTISs showed trends of parr\n8\nemigration during summer and fall, in addition to the expected movement of parr and smolts in\nspring. These data are increasing our understanding of varied life histories of juvenile steelhead;\npaired with other steelhead population work in the subbasin we hope to better understand the\nfactors influencing parr movements. Monitoring of PIT-tagged fish over multiple years is\nproviding information on contribution of various life-history strategies to smolt production and\nadult returns, as well as identifying factors influencing parr movement.\n\nMovements of PIT-tagged adult steelhead were also monitored with our instream PTISs.\nThese data have provided information on timing of adult movements to various parts of the\nwatershed, which allows us to assess adult returns to tributary watersheds within the Wind River\nsubbasin. Determination of adult use of tributary watersheds is providing data to contribute to\nevaluation of the efficacy of the removal of Hemlock Dam on Trout Creek. Hemlock Dam,\nlocated at rkm 2.0 of Trout Creek was removed in summer 2009 and had contributed to\nhydrologic impairment of Trout Creek.\n\nEvaluating restoration efforts is of interest to many managers and agencies so that\nfunding and time are allocated for best results.
