ADAPT Program – Sagkeeng First Nation

DAL Projects in collaboration with Sagkeeng First Nation, submitted a proposal to INAC to perform an assessment of the shoreline at Lake Winnipeg. To date, the nation has lost in excess of 1000 acres of reserve land and vital infrastructure along its shoreline and climate changes pose further risk to accelerating erosion rates. The focus of this study was to provide a revised remedial works plan that identifies the areas of highest risk to further erosion by incorporating a high-level assessment of the potential changes to the region. DAL was perfectly positioned to take on this work as Sagkeeng First Nation had been a client of DAL since the 1990s, and had performed the earlier shoreline assessment and protection works as the project and construction manager for Sagkeeng.

This project combined the best of our multi-disciplinary expertise, collaborating with geotechnical, hydrotechnical and climate change specialists. Through a series of interrelated and multifaceted issues and a fast approaching winter season, DAL initiated a survey of the shoreline, followed by a geotechnical investigation of the shoreline; relevant hydrotechnical information was collected and wave calculations were performed by hydrotechnical engineers; quantifiable climate change factors such as precipitation and flow rate data were analyzed; and all this information was put together to undertake a cost/benefit analyses for protecting various parts of the shoreline.

At the point of this writing, a community consultation is being planned for the residents of Sagkeeng First Nation. The event will present our technical findings and recommendations for protecting areas of interest such as infrastructure; and invite input from the community for what they consider to be of cultural and personal significance.

The findings from this assessment will be published in a report to INAC, and it will have DAL’s recommendations on how to plan for protecting the shoreline in light of the assessed impact of climate change; and the cost benefit ratio for protecting various areas of the shoreline as opposed to losing the shoreline.
