Because the Lillooet River supplies Lillooet Lake, these high flows are directly impacting the lake's condition and increasing the risk levels. Lilʼwat Nation has already expanded an evacuation order and alert for the area along the Lillooet River corridor to Lillooet Lake due to these high-risk river levels.

What we don't know yet

  • Will the dam discharge be reduced to mitigate the high flows?
  • How long will the orange rainfall warnings remain in place for west and inland Vancouver Island?

What would change this answer

Heavy rainfall continues in the regionThe high flows will intensify, potentially requiring further expansion of evacuation orders and increasing the risk to Lillooet Lake.
BC Hydro reduces the dam discharge rateThe high flows along the Lillooet River corridor should decrease, allowing for a reduction in evacuation alerts.
