2000: There is a certain irony about one of the driest places getting the greatest rainfall, and yet that is what happened at usually rain-sparse Vanguard, Saskatchewan on July 3 when a carwash-like downpour flooded the community of 200 people, some 65 km southeast of Swift Current. As much as 375 mm (14.76”) of rain fell in eight hours, the greatest storm for that duration on the Canadian Prairies and one of the most substantial rainfall intensities ever recorded in Canada.
The spectacular thunderstorm produced more cloud-to-ground lightning strikes than that part of southern Saskatchewan would expect in two years. A year's amount of rain left crops in the field drowning and rotting, and roads and rail lines under water. The force of the water crushed cars and farm implements swept away grain bins and soaked large bales. Stranded residents had to be rescued by boat, which rapidly became the carrier of choice on the main street in Vanguard. The flash flood also carried away herds of cattle and drowned dozens of deer and antelope. Some further irony, when millions of liters of contaminated water submerged the water-treatment plant and backed up into homes and businesses, officials had to ship in bottled water from Swift Current.
