Dramatic satellite images show the extent of flood damage in B.C.'s Sumas Prairie following last weekend's historic rainfall. The low-lying rural area, east of Abbotsford's town centre, is mostly farmland and was created by the draining of Sumas Lake in the 1920s. Last week the area suffered extensive flooding as water gushed in from the Nooksack River from neighbouring Washington state, forcing evacuations and killing livestock.
