Flooding from Washington’s Nooksack River overwhelmed B.C.’s Sumas Prairie, forcing 450 evacuations and prompting calls for federal flood mitigation action.

Abbotsford Mayor Ross Siemens slammed the federal government for inaction during severe flooding from Washington’s Nooksack River, which forced 450 evacuations in B.C.’s Sumas Prairie and damaged farms. He urged a Sumas River pump station and better cross-border water management. Floodwaters are receding, but recovery will take days, with officials relocating livestock and assessing infrastructure damage.
