Its been rain that has caused most of it. Basically the entire catchment for the bow river, elbow river, sheep river and highwood river had 3 days of heavy rain. All of dowtown Calgary is flooded, the hockey arenas firs 10 rows are filled with water. Its nuts. Most of the bridges in the area were closed today and are just re opening this evening. 100,000 people evacuated from homes. Some via Combine.
I am lucky in that my house is on high ground and we have nothing to worry about but the devistation is amazing. Highest recorded flow rates in all of our rivers. Google Canmore or Calgary flood pics if you want to see.
