Area: Chilliwack

Preliminary site assessment identified hydraulic capacity, access constraints and potential flooding concerns near the joining of Sqwa:la (Hope Slough) and Stó:lō (Fraser River) area west of Chilliwack, BC. 

Sqwa:la (Hope Slough) flows to the Stó:lō (Fraser River) and is fed by the Hope River, which also connects to the Stó:lō (Fraser River) approximately 12km upstream from the mouth of the slough.

The slough has seen a historic accumulation of sediment, especially at its connection with the Stó:lō (Fraser River), that was increased by the November 2021 ARE. Sqwa:la (Hope Slough) is typically 80–90 meters wide and narrows to only 20 meters wide at the outflow.

This deposition of sediment may cause additional damage to riverbeds, banks, and infrastructure, and may pose a significant threat to the safety of people, properties, infrastructure, and the environment. 

Planned work on this site includes reducing the amount of sediment along the channel towards the connection with the Stó:lō (Fraser River) to improve channel capacity along the project site area. (See map below).
