Technical reports are directed primarily toward a worldwide audience and have an international distribution. No restriction is placed on subject matter and the series reflects the broad interests and policies of Fisheries and Oceans Canada, namely, fisheries and aquatic sciences. Technical reports may be cited as full publications. The correct citation appears above the abstract of each report. Each report is abstracted in the data base Aquatic Sciences and Fisheries Abstracts. Technical reports are produced regionally but are numbered nationally. Requests for individual reports will be filled by the issuing establishment listed on the front cover and title page. Numbers 1-456 in this series were issued as Technical Reports of the Fisheries Research Board of Canada. Numbers 457-714 were issued as Department of the Environment, Fisheries and Marine Service, Research and Development Directorate Technical Reports. Numbers 715-924 were issued as Department of Fisheries and Environment, Fisheries and Marine Service Technical Reports. The current series name was changed with report number 925.

Online Discussion: https://www.youtube.com/watch?v=pHplxCMHmJc CRV Session Sketches, Summary & Topology Information contributed by Ronald Kuhn, Ohio, USA ----------- Seton Lake is a freshwater fjord draining east via the Seton River into the Fraser River at the town of Lillooet, British Columbia, about 22 km long and 243 m in elevation and 26.2 square kilometres in area.[1] Its depth is 1500 feet. The lake is natural in origin but was raised slightly as part of the Bridge River Power Project, the two main powerhouses of which are on the north shore of the upper end of the lake near Shalalth. At the uppermost end of the lake is the community of Seton Portage and the 1 mouth of the short Seton Portage River, which connects Anderson Lake on the farther side of the Portage to Seton Lake. Retrieved Mar. 1, 2015. http://en.wikipedia.org/wiki/Seton_Lake Image courtesy of Larry Bourne Sketch courtesy of Ronald Kuhn, CRV Intermediate Level Student The Bridge River hydroelectric complex consists of three dams and stores water for four generating stations. The system uses Bridge River water three times in succession to generate 492 megawatts, or 6 to 8 per cent of British Columbia's electrical supply. Hydroelectric development of the system began in 1927 and was completed in 1960. Its waters (Downton Reservoir) initially pass through the Lajoie Dam and powerhouse and are then diverted through tunnels and penstocks from Carpenter Reservoir to the two powerhouses on Seton Lake Reservoir.

BRGMON-8 February 2018 Seton Lake Resident Fish Habitat and Population Monitoring Year 3 (2015) Executive Summary Data collection for Year 3 of this proposed 10-year study was completed in 2015. Results for Years 1 and 2 of this program are provided in the previous data report produced for this program in 2015 (Sneep 2015). Where relevant, comparisons across monitoring years for this program have been included in this report. A full synthesis of all results will be conducted following the final year of data collection which is scheduled for 2022. The primary objective of this monitoring program is to “collect better information on the relative abundance, life history and habitat use of resident fish populations in Seton Lake” (BC Hydro 2012). Field studies for the Seton Lake Resident Fish Habitat and Population Monitoring Program (BRGMON-8) were conducted in Seton Lake, as well as Anderson Lake for the first time this year. Data collection in Anderson Lake was included to provide context and comparison for the Seton Lake results. The two lakes are comparably sized, located within the same watershed, and have similar natural inflows; however, Seton Lake is impacted by the diversion from Carpenter Reservoir whereas Anderson Lake is not.

    “Black” Kokanee, a Novel Reproductive Ecotype of Oncorhynchus Nerka Amanda L

    Pagination not final (cite DOI) / Pagination provisoire (citer le DOI) 1 ARTICLE The origin and genetic divergence of “black” kokanee, a novel reproductive ecotype of Oncorhynchus nerka Amanda L. Moreira and Eric B. Taylor Abstract: Kokanee and sockeye salmon are the freshwater-resident and anadromous forms, respectively, of Oncorhynchus nerka. Unique populations of “black” kokanee are found in Lake Saiko, Japan, and in Anderson and Seton lakes in the southwestern interior of British Columbia. They are distinct from other populations of O. nerka in that black kokanee display black nuptial colouration and they spawn between 20 to 70 m below the surface of lakes in the winter or early spring. Analysis of mitochondrial DNA and nine microsatellite loci supported the hypothesis that black kokanee in Lake Saiko and in Anderson and Seton lakes have had a diphyletic origin resulting from at least two episodes of divergence in the North Pacific basin. Further, black kokanee in the Anderson and Seton lakes system were genetically distinct from sympatric populations of sockeye salmon in Gates and Portage creeks (inlets to Anderson and Seton lakes, respectively) and were distinct from one another. Anderson and Seton lake black kokanee differed dramatically from one another in standard length at maturity, but no differences were found between the two populations in size-adjusted maximum body depth or in gill raker numbers. Independent origins of black kokanee represent novel diversity within O. nerka, are consistent with the importance of parallel evolution in the origin of biodiversity, and suggest that independent management regimes are required for the persistence of black kokanee biodiversity within a physically interconnected lake system.
