Phone: (250) 398-3600 The 2004 Adult Coho Assessment of Tributaries of Quesnel Lake 6 November 26, 2004 1.0 Introduction During the latter part of October 2004, John Stace-Smith of Riverside Forest Products Ltd. of Williams Lake’s Soda Creek Division contacted Cariboo Envirotech Ltd with an opportunity to conduct watershed related assessments within their general operating area. It was decided that due to the timing of the request, and the lack of current information on suspected coho spawning streams, that an adult coho salmon habitat and escapement survey should be conducted on tributaries of Quesnel Lake. Quesnel Lake is located in the east Cariboo region of the Interior of British Columbia. It has a surface area of 27,012.717 hectares, a perimeter of 323.801 kilometres, and a known depth of 610 metres. Fish species known to inhabit Quesnel Lake are as follows: ¾ Bull Trout Salvelinus confluentus ¾ Burbot Lota lota ¾ Chinook Salmon Oncorhynchus tshawytscha ¾ Coho Salmon Oncorhynchus kisutch ¾ Kokanee Oncorhynchus nerka ¾ Lake Trout Salvelinus namaycush ¾ Longnose Dace Rhinichthys cataractae ¾ Minnow (general) all cyprinids ¾ Mountain Whitefish Prosopium williamsoni ¾ Northern Pike Minnow Ptychocheilus oregonensis ¾ Peamouth Chub Mylocheilius caurinus ¾ Rainbow Trout Oncorhynchus mykiss ¾ Redside Shiner Richardsonius balteatus ¾ Sockeye Salmon Oncorhynchus nerka ¾ Sucker (general) Catostomus sp. (FishWizard) Interior Fraser River coho salmon, which includes Quesnel Lake stocks are now protected under the Species at Risk Act (SARA). Additionally, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) “has concluded that there is a serious risk of extinction due to several factors. These include: concern that reductions in fishing pressure may be insufficient or not maintained, that marine survivorship may not improve, that habitat loss or deterioration in the watershed continues, and that use of hatcheries threatens recovery” (COSEWIC). Public forums have recently been held to discuss this issue, including one held in Williams Lake on November 17th, 2004. The minutes of this stakeholder session have been included in this report under Tab 17. Additionally, a National Recovery Strategy for Coho Salmon has recently been developed and can be reviewed through the Internet (Recovery Strategy). Quesnel Lake tributaries have historically been known to provide spawning opportunities for adult coho (FishWizard). The Quesnel River Hatchery located in Likely, British The 2004 Adult Coho Assessment of Tributaries of Quesnel Lake 7 November 26, 2004 Columbia, in operation by Fisheries and Oceans Canada from 1981 to 1995 conducted coho salmon assessments on McKinley Creek, a tributary of the Horsefly River, and Summit Creek, a tributary of Quesnel Lake located in the East arm. Enhancement of these two tributaries also occurred through a gamete collection in the fall with the resultant fry being released the following spring. Continuation of the McKinley Creek project as a stock assessment tool is ongoing through the efforts of Fisheries and Oceans Canada and the Cariboo Tribal Council of Williams Lake. 2.0 Methodology Two experienced freshwater fisheries biologists from Cariboo Envirotech Ltd conducted the field portion of the project. The survey involved the use of an 18 foot Gregor jetboat powered by 125 hp jet motor. The crew assessed Quesnel Lake tributaries on a daily basis from October 25th to November 2nd. Access to the stream mouths was primarily by boat and reconnaissance was conducted in the first and second reaches on foot. Although the project was based out of the community of Likely located at the lake outlet, the field crew set up base camps at the ends of both the North and East arms to facilitate ease of access to streams located in these areas. This also alleviated some safety concerns as the field crew traveled in an open boat during some severe weather conditions. Additionally, for reasons of safety, the field crew was provided with a satellite telephone and followed daily check in procedures. During the assessments, standard stream cards were filled out with relevant data and photos were taken in an effort to show habitat conditions. These items can be reviewed in the appendices of this report. It should be noted that although the Federal/Provincial government FDIS program was used to provide the field data, the information has not been transferred to their database program, and is only utilized in this report for ease of data compilation. Discussions were held with Fisheries and Oceans staff Richard Bailey and Adrian Wall from the Coho Recovery Team regarding the project and streams were identified for assessment. It was also felt that the field assessment data would provide some opportunity for comparison with aerial flight counts on the same streams. 3.0 Results Table 1 provides a summary of the streams assessed and relevant information associated with each stream. A total of 15 streams were assessed during the project and adult coho were found in 4 of these streams. One unnamed stream, WSC 160-635400-05400, was added to the survey based on personal communication with a Horsefly resident who had historically trapped an adult coho during his trapping season in this stream (pers. comm.). Aside from Penfold Creek, all the creeks drain directly into Quesnel Lake. The 2004 Adult Coho Assessment of Tributaries of Quesnel Lake 8 November 26, 2004 Table 1: Assessment summary.

  • Eocene Paleo-Physiography and Drainage Directions, Southern Interior Plateau, British Columbia1
    215 Eocene paleo-physiography and drainage directions, southern Interior Plateau, British Columbia1 Selina Tribe Abstract: A map of reconstructed Eocene physiography and drainage directions is presented for the southern Interior Plateau region, British Columbia south of 53°N. Eocene landforms are inferred from the distribution and depositional paleoenvironment of Eocene rocks and from crosscutting relationships between regional-scale geomorphology and bedrock geology of known age. Eocene drainage directions are inferred from physiography, relief, and base level elevations of the sub-Eocene unconformity and the documented distribution, provenance, and paleocurrents of early Cenozoic fluvial sediments. The Eocene landscape of the southern Interior Plateau resembled its modern counterpart, with highlands, plains, and deeply incised drainages, except regional drainage was to the north. An anabranching valley system trending west and northwest from Quesnel and Shuswap Highlands, across the Cariboo Plateau to the Fraser River valley, contained north-flowing streams from Eocene to early Quaternary time. Other valleys dating back at least to Middle Eocene time include the North Thompson valley south of Clearwater, Thompson valley from Kamloops to Spences Bridge, the valley containing Nicola Lake, Bridge River valley, and Okanagan Lake valley. During the early Cenozoic, highlands existed where the Coast Mountains are today. Southward drainage along the modern Fraser, Chilcotin, and Thompson River valleys was established after the Late Miocene. Résumé : Cet article présente une carte reconstituée de la géographie physique et des directions de drainage, à l’Éocène, pour la région du plateau intérieur de la Colombie-Britannique, au sud du 53e parallèle Nord. Les formes de terrain à l’Éocène sont déduites de la distribution et du paléoenvironnement de déposition des roches de l’Éocène et à partir de relations de recoupement entre la géomorphologie à l’échelle régionale et la géologie du socle, d’âge connu.

  • Spawning Site Selection and the Influence of Incubation Environment on Larval Success in Interior Fraser Coho
    Spawning Site Selection and the Influence of Incubation Environment on Larval Success in Interior Fraser Coho Crystal Jane McRae B.Sc. Trent University, 2004 Thesis Submitted in Partial Fulfillment of The Requirements for the Degree of Master of Science in Natural Resources and Environmental Studies (Biology) The University of Northern British Columbia July, 2009 © Crystal Jane McRae, 2009 ABSTRACT Habitat features have been shown to influence salmonid spawning site selection as well as the survival and growth of larval fish throughout incubation. Most studies have been conducted in coastal watersheds, however, and little is known regarding habitat features associated with spawning sites for interior populations of salmon. My study examined factors affecting spawning site selection and incubation success for a population of interior Fraser coho salmon (IFC) ( Oncorhynchus kisutch ), in McKinley Creek watershed, British Columbia. Ground surveys coupled with radio telemetry were used to identify spawning site locations. An information theoretic approach was used to examine the probability of spawning site use based on habitat features. Incubation of larval fish within in-stream artificial redds allowed for the assessment of survival and growth in different incubation environments. The spawning habitat use of IFC throughout the McKinley Creek watershed was more extensive than previously realized. Hyporheic conductivity, dissolved oxygen, temperature and specific discharge were the best indicators of spawning site selection. Despite significant differences in habitat variables between used and unused spawning sites, survival and growth of larval IFC did not differ between sites; maternal effects were greater than incubation habitat features. This study has provided critical information about spawning site selection and the incubation environment of IFC, and has contributed to the understanding of the influence of habitat features on salmonids in interior watersheds.

  • Effects of Past and Present Mining on Fine Sediment Geochemistry of Floodplain Soils, Horsefly River, BC, Canada
    Effects of past and present mining on fine sediment geochemistry of floodplain soils, Horsefly River, BC, Canada Master thesis Marjolein Vogels 3345971 Supervisor: Dr. M. Van Der Perk Utrecht University Faculty of Geosciences Department of Physical Geography April, 2013 1 Cover: Quesnel River, Likely, British Columbia, Canada (2012) 2 Abstract Active and abandoned mine sites are known to be a dominant source of metal contamination in fluvial systems worldwide. Small-scale mining of minerals like gold, copper and zinc has been prevalent in interior British Columbia, Canada since the 19 th century. The region is also characterized to provide an important habitat for wildlife of which the river gravel beds for several salmon species are a prime example. This thesis investigated the impact of past and present mining on floodplain soils of the Horsefly River, BC, Canada. The abandoned Black Creek placer mine was specifically studied. Floodplain cores were analysed for metal distributions of arsenic, cadmium, zinc, lead, selenium and copper, elements often associated with gold placer mining. The anthropogenic part (residual part) of these metal concentrations was determined by subtracting that part stemming from local geology from the total concentration measured. The concentrations representing local geology were determined using a normalization procedure combined with regression analysis. The cores were also analysed for 210 Pb abundance from which age-depth profiles were established. Three floodplain cores were analysed this way: (1) upstream of the Black Creek inlet into the Horsefly River, (2) downstream of the Black Creek inlet, (3) at the Horsefly delta (55 kilometers downstream). It was concluded that there were no present effects of the Black Creek mine on the fine sediment geochemistry of the Horsefly floodplain.

Spring Grizzly Bear viewing is nothing short of wondrous and amazing with new life springing forth and fresh crisp air in the mountains fragrant with the scents of new growth. In early spring the bears emerge from their dens hungry and in search of food for themselves and their young offspring. We find the grizzlies on the mountain slides, in the mountain valleys where it greens up first and on the estuaries of the rivers. The early spring grasses and sedges sprouting in the lowlands and along the river banks and lakeshores draws the bears to the lower elevations where feed is plentiful after the long winter hibernation period. Watch the entertaining antics of the grizzly cubs with their mothers and the courtship of the mating pairs. Access is by 4x4, multi-passenger ATV, hiking and jetboat on rivers. In July and August as the summer temperatures climb the grizzlies move to higher elevations into the boreal forest and the high alpine basins and valleys in the Cariboo Mountains. Viewing, at this time involves amazing hiking through mountain meadows, boreal forest and into the alpine. Some bears stay on the rivers as they await the early summer Chinook salmon run. We explore the river ecosystems by jetboat as we watch the bears, moose, deer, beaver, and other wildlife and birds and perhaps a wolf, or otter.

  • Temperature Preference, Aerobic Scope and Upper Thermal Tolerance in Sympatric Juvenile Chinook Salmon (Oncorhynchus Tshawytscha) and Coho Salmon (O
    TEMPERATURE PREFERENCE, AEROBIC SCOPE AND UPPER THERMAL TOLERANCE IN SYMPATRIC JUVENILE CHINOOK SALMON (ONCORHYNCHUS TSHAWYTSCHA) AND COHO SALMON (O. KISUTCH) by Hannah Sungaila B.Sc., University of British Columbia, 2009 THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN NATURAL RESOURCES AND ENVIRONMENTAL STUDIES (BIOLOGY) UNIVERSITY OF NORTHERN BRITISH COLUMBIA November 2018 © Hannah Sungaila, 2018 ABSTRACT Populations of Pacific salmon (Oncorhynchus spp.) are locally adapted to environmental conditions, with temperature being the most important abiotic factor. Wild Chinook salmon (O. tshawytscha) and coho salmon (O. kisutch) from the Horsefly River system in central British Columbia (BC) vary in adult migration timing, but often rear sympatrically as juveniles. These species provide an interesting opportunity to investigate adaptations to the environment in the juvenile life-history stage, which may differ from adaptations at the adult stage. I conducted three laboratory studies with wild-caught Horsefly River juvenile Chinook salmon and coho salmon to compare thermal preference, performance and tolerance between species. Temperature preference did not differ significantly between Chinook salmon and coho salmon. Aerobic scope (difference between maximum and routine metabolic rates) was also similar between the two species, and neither showed a distinct temperature optimum for peak physiological performance within the range of temperatures tested. Coho salmon had a significantly higher upper thermal limit compared to Chinook salmon, although the differences were small (0.26 ºC) and may not be biologically meaningful. Thus, these two populations appear to be well adapted for their current environmental conditions rather than show any tendencies to be differentially suited to selective pressures they will experience as adults.
