Lakelse sockeye stocks experienced a significant decline for several cycles from the late 90’s through 2010 and were identified as a high priority by DFO North Coast Area. The construction of a regulated-flow side-channel in Lower Williams Creek has been identified by the DFO North Coast Resource Restoration Unit as the greatest potential opportunity to further improve Lakelse sockeye stocks and safeguard current spawning and incubation.
Williams Lower Channel : Site 1.
The construction of a regulated-flow side-channel in Lower Williams Creek was identified by the DFO North Coast Resource Restoration Unit as the greatest potential opportunity to further improve Lakelse sockeye stocks and safeguard current spawning and incubation. Feasibility for this work was very successful with the early support of BC Parks for a channel within the Lakelse Lake Provincial Park, which is the only stable reach in Lower Williams. An excellent channel route was surveyed and initial design work was initiated. Further development of this channel was halted after BC Parks Management toured the proposed site with DFO, reviewed the report outlining the proposed work and decided not to support a project in the Park. The site tour sparked concern for several old growth and some culturally modified trees which were near the proposed channel route Although we could easily avoid them, we understood and respected their management decision.

The Takshanuk Watershed Council (TWC) will conduct a salmon habitat assessment of the Kelsall River in Southeast Alaska using a combination of on-the-ground fluvial habitat surveys and remote-sensed classification/delineation. TWC will classify habitat types; determine the physical habitat values and channel metrics.

This project will complete the original screened intake project begun in the spring of 2013. That project, funded by the Pacific Salmon Commission Northern Fund enabled the water intake for the SJ Hatchery to be completely screened.

It is proposed that formal efforts be continued in order to improve sockeye salmon migration access both in and out of Tahltan Lake by ensuring passage thru numerous beaver dams. Concurrently, it is proposed that a small crew clear and expand the trail below Tahltan Lake along Johnny Tashoots Creek. This trail was initially established specifically to make it feasible for Fisheries crews to get to the beaver dam sites, but the unmaintained trail has become slow and unsafe to traverse.
Over the years it has been observed that these beaver dams can restrict or block salmon passage, for both out-migrating sockeye smolts and in-migrating adults. To note, there are currently several other adult salmon passage challenges on the Tahltan River (i.e. the previous landslide and Decheeka Falls), which consume adult migration energy expenditures. However, those other sites are not presumed to affect smolt out-migration as has been the seen with the beaver dams.
An extensive amount of dedication is currently provided for the effective stock assessment and enhancement of Tahltan Lake sockeye. Therefore, the regular field staff at Tahltan Lake needs to constantly maintain operations, leaving inadequate time for dedicated access or trail improvement activities. In particular, to properly conduct this work, there is a necessity of carrying equipment and camping overnight at the various downstream sites.
For 20 years Tuya Lake has been an important part of the Stikine River sockeye enhancement program having demonstrated a very high productive capacity in terms of rearing potential. However, it has not been monitored with the same consistency and effort as the other Transboundary enhancement sites. If sockeye planting into Tuya Lake is to continue then at least a basic level of consistent monitoring should also be conducted. Without such, a change in the trend of rearing capacity or potential for Tuya Lake would likely to go unnoticed.
The goal of this project is to capture a minimum of 200 out-migrating Tuya Lake sockeye smolts for subsequent biological sampling. Such would include the collection of length, weight, age and otolith data. Upon sample analysis and comparison to previous data, this would provide indicator information regarding Tuya sockeye smolt condition, lake productivity and thermal marked / unmarked ratios.

For this study several new enhancement opportunities for Stikine sockeye were investigated in order to provide details upon which enhancement implementation could be pursued. For 2015, it is proposed that Tahltan Lake should be the sole focus of this final year of the enhancement feasibility study. This work would centre upon collecting and analyzing data to inform the detailed design and budget for creating additional sockeye spawning habitat at Tahltan Lake. Information thus far provides strong indication that this would be a promising new enhancement initiative. Analysis and modeling of hydrogeology data is considered to be a critical precursor to construction of the spawning area.
The intent of diversifying or expanding the existing Stikine enhancement program was reflected in the updated 2009 Transboundary PST arrangements. It states that: For the duration of this Chapter, the ‘Parties will pursue a diverse program to enhance sockeye production in the Stikine River …’ and that ‘The existing enhancement program may be expanded to include new activities such as barrier removal, habitat improvement and/or other agreed enhancement projects.’ (PST Appendix to Annex IV, Chapter 1, section 5.)
Tahltan Lake has ranked highest in enhancement feasibility since the beginning of this study. The lake is known to be spawning limited in terms of productivity and also to have underutilized rearing capacity. Field surveys during the feasibility study thus far have indicated that an area of riparian wetland on the north-east lakeshore has high potential for the creation of new sockeye spawning habitat. Beneath the wetland there is a partially confined aquifer within a gravel paleo-channel, which will likely provide essential groundwater flow and suitable substrate. The creation of a new spawning area would not only serve to increase wild productivity, but could also be utilized as an alternative site for the collection of brood stock. Such would be a useful manner of supplementing needs and addressing challenges of the current egg-take project.

Sockeye enhancement on the Stikine River is a key component of the recently re-negotiated Canada/U.S. agreement on the Transboundary rivers. The egg-take at Tahltan Lake and subsequent incubation of the eggs at the Snettisham hatchery has been vital in the production of enhanced sockeye salmon, achieving the target of 100,000 enhanced adults per year thereby significantly increasing the Stikine River fishery value to Canada and the US.

Current methodology for estimating escapement and run size of Nass Area Chum salmon relies on a number of untested assumptions, resulting in considerable uncertainty regarding stock status. We propose a detailed review of recent and historical escapement data for Nass Area Chum salmon stocks, combined with strategically targeted escapement surveys, to refine and standardize the methodology used to calculate Nass Area Chum salmon escapement and run size.
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.
