Fall Chinook Salmon Spawning Ground Surveys in the Snake River Basin Upriver of Lower Granite Dam, 2005 Annual Report.

Redd counts are routinely used to document the spawning distribution of fall Chinook salmon (Oncorhynchus tshawytscha) in the Snake River basin upriver of Lower Granite Dam. The first reported redd counts were from aerial searches conducted intermittently between 1959 and 1978 (Irving and Bjornn 1981, Witty 1988; Groves and Chandler 1996)(Appendix 1). In 1986, the Washington Department of Fish and Wildlife began an annual monitoring program that, in addition to the Snake River, included aerial searches of the Grande Ronde River the first year (Seidel and Bugert 1987), and the Imnaha River in subsequent years (Seidel et al. 1988; Bugert et al. 1989-1991; Mendel et al. 1992). The U. S. Fish and Wildlife Service and Idaho Power Company began contributing to this effort in 1991 by increasing the number of aerial searches conducted each year and adding underwater searches in areas of the Snake River that were too deep to be searched from the air (Connor et al. 1993; Garcia et al. 1994a, 1994b, 1996-2005; Groves 1993; Groves and Chandler 1996). The Nez Perce Tribe added aerial searches in the Clearwater River basin beginning in 1988 (Arnsberg et. al 1992), and the Salmon River beginning in 1992. Currently searches are conducted cooperatively by the Nez Perce Tribe, Idaho Power Company, and U.S. Fish and Wildlife Service. Our objective for this report was to consolidate the findings from annual redd searches into a single document, containing detailed information about the searches from the most recent spawning season, and summary information from previous years. The work conducted in 2005 was funded by the Bonneville Power Administration and Idaho Power Company

Demonstrationsanlage zur Abgasentschwefelung bei einem Schmelzkammerkessel Abschlussbericht

Stora Billerud GmbH, Werk Arnsberg, hat die Kohleversorgung durch die Ruhrkohle Aktiengesellschaft (RAG) im sogenannten Jahrhundertvertrag sichergestellt. Diese Kohleversorgung, als Mischlieferung verschiedener Zechen, beinhaltet einen minimalen Schwefelgehalt von 1,1% bezogen auf Rohkohle und kann nicht weiter abgesenkt werden. REA-Anlage musste in vorhandenes Gebaeude integriert werden. Verfuegbarkeit von 98% wurde gefordert. Es wurden fast ausschliesslich GFK und PP als Werkstoffe fuer suspensionsfuehrende REA-Komponenten und Rohre verwendet. Ruehrwerke und Hauptwaescherpumpen aus REA-festem Stahl. PLS und Visualisierung erleichtern Betrieb und Ueberwachung der REA. Die Entschwefelung von 75.000 m"3 Rauchgas unter 200 mg/m"3 ist moeglich. (orig.)Coal supply to Stora Billerud GmbH at Arnsberg, Bavaria, by Ruhrkohle Aktiengesellschaft (RAG) is ensured by the Agreement on Electric Power Generation from Coal. The coal supplied originates from different mines. It has a minimum sulphur content of 1.1% as referred to raw coal which cannot be lowered. The flue gas desulphurisation system had to be integrated in an existing building. An availability of 98% was required. Only CFC and PP were used as materials for pipes and other components exposed to the suspension. Agitators and primary scrubber pumps were made of sulphur-resistant steel. Electronic and visual control facilitate operation and monitoring. Desulphurisation efficiencies amount to less than 200 mg/m"3 for 75,000 m"3 of flue gas.

Durchfuehrung von Laermschutzmassnahmen in einer vollkontinuierlich durchlaufenden Papierfabrik Abschlussbericht

One of the main sources of noise in paper mills is the paper machine, which on account of its dimension and technical demands cannot be encased. For noise pollution abatement the following measurers are supposed: The paper machine shup and the internal traffic ways in the fully continuous paper mill should be built over with a new proof, and optimized aerators and de-aerators have to be installed. By these measures of sound insulation the sound level can be reduced by 11-12 dB. (orig.)Eine der Hauptlaermquellen in Papierfabriken ist die Papiermaschine, die infolge relativ grosser Abmessungen und prozesstechnischer Notwendigkeit nicht fuer eine Kapselung geeignet ist. Durch Ueberbauung der Papiermaschinenhalle sowie der innerbetrieblichen Verkehrswege bei vollkontinuierlich durchlaufendem Betrieb, sowie Einbau einer schalltechnisch optimierten Be- und Entlueftung wird demonstriert, dass der Beurteilungspegel des Gesamtwerkes durch diese Massnahmen um ca. 11-12 dB(A) gesenkt werden kann.

Influence of river conditions on survival and travel time of Snake River subyearling fall chinook salmon

From 1995 to 2000, subyearling fall chinook salmon Oncorhynchus tshawytscha reared at Lyons Ferry Hatchery were PIT-tagged at the hatchery, trucked upstream, acclimated, and released into free-flowing sections of the Snake River weekly from early June to mid-July. We estimated survival probabilities and travel time through the lower Snake River and detection probabilities at dams for each weekly release group. The average median time between release and arrival at Lower Granite Dam was 43.5 d. For each group, we split this time into two nearly equal (on average) periods: one when most fish in the group were rearing and one when most fish had apparently begun active seaward migration. The estimated survival for hatchery fish from release to the tailrace of Lower Granite Dam decreased with release date each year. The estimated survival through this reach was significantly correlated with three environmental variables: survival decreased as discharge ( flow ) decreased, as water transparency increased, and as water temperature increased. Because the environmental variables were highly correlated among themselves, we were unable to determine whether any factors were more important than the others. All three factors have plausible biological consequences for rearing and actively migrating fish, and survival is probably influenced by all of them and possibly by interactions among them as well. Summer flow augmentation will increase discharge and decrease water temperature (provided the additional water is not too warm) and probably increase the speed of seaward migration of smolts, all of which are beneficial to the recovery of threatened Snake River fall chinook salmon
