  Citation × Citation Citation Abstract Copy Title: Catherine Creek Spring Chinook Salmon Hatchery Program Review - 2011 Abstract -- This paper provides background information, program development history, and an assessment of program performance for the Catherine Creek spring Chinook salmon hatchery program. We cover the time period from initiation of the program in the mid-1990s to present. General background information and pre mid-1990s hatchery program performance were previously presented in Grande Ronde Basin Spring Chinook Salmon Hatchery Review: Introduction and the Early Years. The Catherine Creek spring Chinook hatchery program was initiated with collection of wild parr for the Captive Broodstock Program in 1995 due to the depressed status of this population (Figure 1). Adult trapping and smolt acclimation facilities were constructed to implement the program and are operated by the Confederated Tribes of the Umatilla Indian Reservation (CTUIR). These facilities function as satellite facilities of Lookingglass Fish Hatchery (Figure 2). Lookingglass Fish Hatchery (LFH) serves as the adult holding, spawning, incubation, and rearing facility for the program. Smolts are transported from LFH to the Catherine Creek acclimation ponds for a short period of acclimation in the spring prior to release. Annual adult mitigation, smolt production, and brood year specific smolt-to-adult return goals were developed for the Catherine Creek program to represent 16.67% of the total Grande Ronde River basin goals (Table 1).

  Citation × Citation Citation Abstract Copy Title: 2009 Foskett Spring Speckled Dace Investigations Progress Report 2009 Abstract -- Speckled dace (Rhinichthys osculus) are geographically widespread throughout the western United States and occur in many isolated subbasins and interior drainages in south-central Oregon. The Foskett Spring speckled dace (R. osculus ssp.) is represented by a single population that inhabits Foskett Spring (Figure 1) on the west side of Coleman Lake (Warner Lakes subbasin) in Lake County, Oregon. Foskett speckled dace was listed as threatened under the federal Endangered Species Act in 1985 (U.S. Fish and Wildlife Service 1985). The Foskett speckled dace became isolated in Foskett Spring at the end of the Pluvial period (~9,000-10,000 years ago). Foskett Spring is a natural spring that rises from a springhead pool, flows through a narrow spring brook into a series of shallow marshes, and then disappears into the soil of the normally dry Coleman Lake (Figure 1). A second population in Dace Spring, located approximately 0.8 kilometer south of Foskett Spring, was established from an introduction of 100 fish from Foskett Spring in 1979-1980 (Williams et al. 1990); however recent surveys have failed to document their continued existence at this location. In 1987, the U.S. Bureau of Land Management (BLM) acquired, through exchange, the 65 hectare parcel of land containing Foskett and Dace Springs. Both sites were fenced to exclude livestock. The Recovery Plan for the threatened and rare native fishes of the Warner Basin and Alkali Subbasin states that Foskett speckled dace will probably not be delisted in the near future because of its extremely isolated range and potential for degradation of its habitat from localized events (USFWS 1997). The primary recovery objective for this species is long-term persistence through preservation of its native ecosystem. The plan further states that the conservation and long term sustainability of this species will be met when: 1) long-term protection of its habitat, including spring source aquifers, springpools and outflow channels, and surrounding lands is assured; 2) long-term habitat management guidelines are developed and implemented to ensure the continued persistence of important habitat features and guidelines include monitoring of current habitat and investigation for and evaluation of new spring habitats; and 3) research into life-history, genetics, population trends, habitat use and preference, and other important parameters is conducted to assist in further developing or refining criteria 1) and 2), above. Actions needed to meet these criteria include protecting the fish population and its habitat, conserving genetic diversity of the fish population, ensuring adequate water supplies are available, monitoring of the dace population and habitat conditions, and evaluating long-term effects of climatic trends on recovery of this fish population. The purpose of this investigation was to determine the status of the federally listed Foskett Spring speckled dace and its habitat. This report updates a monitoring program initiated in 2005 by ODFW (Scheerer and Jacobs 2005) by providing results of monitoring conducted in 2009. Specifically, this monitoring program calls for biannual estimates of population abundance, assessments of distribution and demographic parameters and assessments of physical habitat conditions.
