2012 Final FWCP Seton Corridor REPORT Seton River Corridor Corridor REPORT 2012 13 2. GOALS AND OBJECTIVES The Sekwʼelʼwas Seton Wildlife Corridor Restoration Feasibility Study, and the ongoing vegetation, spawning gravel, fish and wildlife surveys carried out in 2010-13 were implemented as a result of the restoration work taking place at the Powerhouse Restoration site and the increasing awareness of loss of intact wildlife corridors and habitat, both in-stream and upland. The question was by enhancing and creating wildlife habitat at the Powerhouse site, are we creating a wildlife sink? Can we provide corridors that wildlife can use to traverse the area between Seton Lake and the Fraser River in a safe way for both wildlife and people? Can we increase both spawning and rearing habitat in the corridor, including the rivers and the three existing spawning channels? The Goals of Sekwʼelʼwas Seton River Corridor Conservation and Restoration Project are to: ⇒ determine the health of the river, spawning channels and upland corridor; and ⇒ gather data that will provide information to stakeholders on possible: • Category 1: Conservation areas • Category 2: Restoration areas • Category 3: Sustainable Management areas • Category 4: Wildlife Corridors that provides movement across the landscape. The Objectives during the 2012-13 study were to: ⇒ continue networking with interested stakeholders and engage partners in development of a long-term ecological plan for the corridor; ⇒ map and survey upland ecosystem habitats in the middle corridor (building on work already completed in the lower corridor); ⇒ complete spawning gravel condition sampling of the Lower and Upper Spawning Channels; ⇒ complete fish stock assessment at the Lower and Upper Spawning Channel; ⇒ establish baseline reptile survey grids and monitor; ⇒ complete two Interior Western Screech-owl surveys; ⇒ remove invasive weeds and replant with native plant species at Lower Spawning Channel (0.5ha area); ⇒ provide training and capacity building in ecological survey methods and restoration techniques; ⇒ provide watershed educational and volunteer stewardship opportunities. Cayoose Creek Stʼatʼimc have exceeded the goals and objectives set out in the revised Application 12.W.SON.02. The work carried out during 2012/13 provides a strong framework on which to develop a management strategy with various stakeholders that will increase the resilience of the Seton River corridor, decrease fragmentation and conserve critical habitats that benefit a wide range of wildlife species, including species-at-risk. The ultimate goal is to conserve and/or restore a functioning habitat network that maintains ecological processes and provides for the movement of native species between key ecosystem spaces, while still taking into account the human impacts and requirements. Seton River Corridor Corridor REPORT 2012 14 3. STUDY AREA 3.1 Site Location The project site is located within the traditional territories of the Stʼatʼimc, just southwest of the town of Lillooet. The Seton River basin is located in the rainshadow of the southern coastal mountains about 235 kilometres northeast of Vancouver. The Seton watershed begins in the headwaters of Gates Creek, which flows into Anderson Lake, through Seton Portage, spilling into Seton Lake. The Seton River flows east out of Seton Lake and runs approximately 4.7 kilometres where it drains into the Fraser River. Much of the flow coming from Seton Lake is diverted via the Seton Canal to the Seton Powerhouse on the Fraser River. The area includes three spawning channels - Upper Seton River Spawning Channel (USC) and Lower Seton River Spawning Channel (LSC) and a smaller spawning channel on Cayoose Creek within the FortisBC hydroelectric complex. The boundaries created for the corridor plan includes the entire stretch of the Seton River corridor from Seton Lake to the Fraser River, and incorporates the Seton and Cayoose Rivers, three spawning channels, the Seton Canal, Powerhouse site, the upland habitats and cliffs on both sides of the rivers (Map 2 - blue boundary). This map also shows the work already carried out at the Powerhouse and Mariposa Flat sites (orange boundary), and the Lower Seton Corridor (purple boundary). The 2012-13 survey areas include the LSC, USC, and the riparian/upland areas running along the south bank of the Seton River between the LSC to the USC. Working with stakeholder partners we were also able to complete surveys of the Cayoose Creek area at the FortisBC IPP complex and under the BC Hydro Transmission Lines.

  • Preliminary Calibration of a Numerical Runout Model for Debris Flows in Southwestern British Columbia
    7th International Conference on Debris-Flow Hazards Mitigation Preliminary calibration of a numerical runout model for debris flows in Southwestern British Columbia Sophia Zubryckya,*, Andrew Mitchella, Jordan Aaronb, Scott McDougalla a Department of Earth, Ocean and Atmospheric Sciences – University of British Columbia, Vancouver, British Columbia, Canada bDepartment of Engineering Geology – ETH Zürich, Zürich, Switzerland Abstract Debris-flow hazard and risk assessments require reliable estimates of inundation area, velocity and flow depth to evaluate spatial impact and impact intensity. Semi-empirical numerical runout models that simulate bulk flow behavior with simple rheological models are useful in forecasting these parameters, however, they require calibration by back-analyzing past events. This paper presents the back-analysis of six debris flows in southwestern British Columbia using a novel automated calibration approach that systematically optimizes the Dan3D runout model to fit field observations. The calibration method yielded good simulations of runout length, but under-predicted flow depths in some cases, and over-predicted velocities in all cases. The best-fit Voellmy rheology parameters for the studied cases ranged from 46 to 531 m/s2 for the turbulence coefficient and 0.08 to 0.18 for the friction coefficient. There is a potential inverse correlation between friction coefficient and event volume. Calibrated parameters were compared to morphometric parameters for the study sites, which may be useful for guiding parameter selection once a larger dataset is calibrated. Ongoing work is focused on refining the calibration technique, including standardization of input parameters more relevant to debris flows. The long-term goal is to apply the technique to a larger dataset of debris-flow cases and provide practitioners with better guidance on the selection of model input parameters for forecasting purposes.

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.

  • The Reproductive Biology of Steelhead (Oncorhynchus Mykiss) in the Bridge and Seton Rivers, As Determined by Radio Telemetry 1996/97 and 1998/99
    The Reproductive Biology of Steelhead (Oncorhynchus mykiss) in the Bridge and Seton Rivers, As Determined by Radio Telemetry 1996/97 and 1998/99 Prepared for: The Ministry of Environment, Lands & Parks Fisheries Branch, Southern Interior Region 1259 Dalhousie Dr. Kamloops, BC V2C 5Z5 Prepared by: Stacy Webb, Robert Bison, Al Caverly and Jim Renn Abstract The 1996/97 and 1998/99 studies of the spawning migrations of Bridge and Seton River steelhead were part of a larger study investigating the migration behaviour and stock composition of interior Fraser River steelhead. Steelhead were radio-tagged in the fall of 1996 and 1998 in the Lower Fraser River and in the winter/spring of 1997 and 1999 in the Middle Fraser River. Tagging effort was concentrated at the Seton/Fraser River confluence during the winter/spring captures, specifically to study Bridge and Seton River steelhead. A total of 15 steelhead were tracked during the 1997 spawning season and 18 steelhead were tracked during the 1999 spawning season in the Bridge and Seton watersheds. Immigration into the Seton and Bridge Rivers started around the middle of April and finished during the second week of May. Immigration into the Bridge and Seton Rivers in 1999 occurred primarily during the last two weeks of April. Spawning in the Bridge and Seton watersheds in 1997 started during the second week of May and ended around the middle of June. Spawning in the Bridge and Seton watersheds in 1999 occurred a little earlier, starting during the second week of April and finishing during the first week of June.

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.

Page i Bridge-Seton Water Use Plan Seton River Habitat and Fish Monitor: BRGMON-9 January, 2015 Executive Summary The objective of this monitoring program is to monitor the response of fish habitat and fish populations to variations in Seton Dam flow operations. This monitor combines old and new approaches to better understand the status of the Seton River fish populations and how different life histories may be affected by Seton Dam operations. The data collected on juvenile and adult fish populations will, over time, allow us to identify trends and patterns that will enable us to make inferences about the effect of flow on habitat, species abundance and diversity. In 2014, we collected data through habitat (depth, velocity) surveys, which allowed us to quantify useable habitat for Rainbow Trout, Coho and Chinook juveniles in the Seton River. Repeating the surveys at established sites enabled us to monitor the effects of flows on each habitat type. In 2014, habitat surveys were completed at four different discharges: 12, 15, 25 and 27 m3/s. Overall, it appears that as flows increase, useable habitat decreases. However, this change is not consistent between habitat types and species.
