Work on the slide in 2021, took place for a month, starting in August and commencing in the first week of February. Manual manipulation (wedge and feathering) was used to create a channel through the remaining rock debris. No blasting took place because of fire restrictions.
The work was followed by several rain events. At the end of September, hatchery staff seined a pool in the upper river and were excited to find over 140 coho in the net. This is the largest number of fish that have travelled to the upper river (without being transported) since the slide occurred in 2014. Most of the fish from the seine were marked and released, the rest were taken to the hatchery for broodstock.
On November 15th, 2021 the Seymour River flows reached 502 cubic meters per second. This significant rain event redistributed a lot of rocks in the slide area.
We are hoping that no more rock manipulation will be needed and that the goal to restore migration has been met. We will do a final assessment in the summer of 2022.
