PSC Infrastructure Upgrade

This project would provide computer hardware and software infrastructure upgrades at the PSC Secretariat offices to support the implementation of SharePoint. SharePoint is an information and document management solution that will support an array of PSC bodies and the Fund Committees (the “PSC Family”) with virtual workspace, data archives, document libraries, and other functions accessible online.
The immediate objective is a sustainable hardware infrastructure to support the growing needs of the PSC Family for virtual workspace and online collaboration for the next five years. This project would provide two new physical servers configured as a Hyper-V environment (virtual environment). A Hyper-V environment allows you to house multiple virtual servers, which provide different services, on one or more physical servers. This infrastructure would permit the Secretariat to develop virtual SharePoint workspace (“portals”) as a benefit for the PSC Family and Secretariat operations.

Chilko River Chinook Salmon Mark-Recapture (Fraser River Summer-run Age 1.3 Stock Group)

The primary goals of the Chilko River Chinook Salmon Mark-Recapture Project are to develop and estimate the spawning abundance that meets or exceeds the Chinook Technical Committee data standard for escapement indicator stocks. Specifically to determine:

1) estimates of spawning escapement by age and sex that will, on average, attain a coefficient of variation (CV) of 15% or less on the spawner estimates; and

2) consistent estimates that are asymptotically unbiased.

Additional objectives include bias testing of application and recovery data, and improving the efficiency of the study in-season and annually.

Radio Telemetry Investigation to Test Closure Assumptions Underpinning Escapement Estimates for the Harrison Stock (Fraser River Fall-run Age 0.3 Stock Group)

Canadian Department of Fisheries and Oceans (CDFO) Fraser Stock Assessment have been delivering a high-precision Chinook salmon mark-recapture program on the Harrison River since 1983. The Harrison River mark-recapture project is the escapement indicator stock for the Fraser River Fall stock group. Program staff also conduct a SSP mark recapture on Chilko River and annual mark-recapture programs on the Lower Shuswap, Middle Shuswap and Nicola rivers; which generate highly precise (CV < 15%) escapement estimates by age, sex, and hatchery contribution. CDFO staff have considerable expertise in the delivery of telemetric assessments of fish behaviour to determine whether or not assumptions of distribution and closure have been met. Fraser Stock Assessment staff have successfully conducted similar telemetry studies on the Lower Shuswap, Middle Shuswap and Chilko rivers.
The Chilliwack River exploitation rate indicator stock is used to represent the distribution of the Harrison Chinook stock. The mortality distributions from the CTC exploitation rate analysis, shows that the stock occurs mainly in the West Coast Vancouver Island (WCVI) aggregate abundance based management (AABM) fishery and US and Canadian individual stock based management (ISBM) fisheries. The stock has high fishery management importance because of its large exploitation in the WCVI AABM, US ISBM and Canadian ISBM fisheries and large abundance.

Water Storage Feasibility on East Coast Vancouver Island

Feasibility of stream flow improvement projects continued in collaboration with fisheries agencies, First Nations, regional district and municipal governments, landowners, area streamkeepers and other ENGOs. Select east coast Vancouver Island (ECVI) watersheds were first prioritized in 2006 and have been reviewed annually by Fisheries and Oceans Canada (DFO) and Ministry of Environment (MoE; now Ministry of Forests, Lands and Natural Resource Operations, MoFLNRO). Evaluation involved a multifaceted process involving biological, hydrological and engineering assessments required for landowner consent, public support and regulatory approval. The work was then further focused on five high priority watersheds/sites Craigflower (Thetis Lake), Millstone (Brannen Lake), Englishman (Shelton Lake), Courtenay (Wolf Lake), and Quatse (Quatse Lake) where new storage could be developed or where existing storage could be improved or increased.

Cowichan River – Stoltz Bluff Sediment Remediation

Stoltz Bluff is a deposit of glacial sediment that extends for approximately 600 m at the outside of a natural meander bend on the Cowichan River, 27 km upstream of Cowichan Bay. Stoltz Bluff was previously identified as the largest point source of fine sediment on the river, representing on average 35-45% of the river’s annual total suspended sediment (TSS) load (KWL Assoc. Ltd. 2005). This is significant in that effective sediment management was identified as the second highest fish habitat restoration priority in the Cowichan Recovery Plan, prepared for Cowichan Tribes’ Treaty Office (LGL Ltd. 2005).
The primary objective of a potential Stoltz Bluff remediation project evolved over 25 years to become “the effective control of massive sediment transport from the bluff (i.e., 10,000-28,000 m3/year since 1993) (KWL Associates Ltd. 2005)), that had been negatively affecting Cowichan River fish habitats and stocks for many kilometres downstream (Burt and Ellis 2006).” The recent Cowichan River Watershed Health and Chinook Initiative (Ayers 2017) reemphasized the value of improved year-round water quality and salmonid spawning habitat as an ongoing strategic management objective.

Beginning in July 2006, the BC Conservation Foundation (BCCF) coordinated a major sediment remediation project at Stoltz Bluff. Work included construction of an engineered 600 m rip-rap berm and terrace, complete with a series of weirs, channel gradient controls and bioengineering treatments designed to move river flows away from the base of the bluff and prevent further bank erosion and major slope failures.

The initial phase of the project took 10 weeks to build, and was supported by a group of seven partners who contributed $830K in funds and in-kind construction materials (including $250K from PSC). For 10 years following the project’s inception, there was a significant improvement in the river’s water quality (i.e., TSS and turbidity) and downstream fish habitats (Gaboury et al. 2012), which is thought to have contributed to incremental gains in annual returns of the river’s fall Chinook and chum salmon stocks, as well as winter steelhead.

However, since 2014, there has been a notable (and even dramatic) change in slope stability at Stoltz Bluff, apparently prompted by the cyclical return of wetter winter weather conditions (McQuarrie 2017). Mass wasting events in the Bluff’s gullies and numerous smaller slope failures have collectively overwhelmed existing sediment retention infrastructure, resulting in higher sediment loads entering the Cowichan River. If this is not effectively mitigated in subsequent annual maintenance activities, a decade of improved spawning conditions will likely become incrementally reversed.
