On December 7, 2014, 80,000 cubic metres of rock and debris slid into the canyon blocking the Seymour River. River water levels upstream of the slide rose by 10 meters and forced the removal of Twin Bridges. In the next year Seymour Hatchery staff and volunteers continually monitored adult and juvenile fish. The results found that no migration was occurring upstream or downstream of the slide area!

In the fall of 2015 two engineering firms were hired to determine the best way to reduce the slide debris to enable greater water flows and fish migration. Seven different recommendations were made. A Roundtable was formed with all the stakeholders and partners to decide on one of the recommendations. The partners decided on drilling and rock breaking over a 2 – 5 year period as the best way to restore migration for all species on the Seymour River.

Since then, Seymour Salmonid Society, has taken the lead in managing and fundraising for the rockslide mitigation project.

Thanking our generous funding partners and stakeholders, including:
