When Canadian astronaut Chris Hadfield installed a new “disaster cam” in the International Space Station last January, he had no idea that the first event the camera would record would be the flood that devastated parts of Calgary in June.

The camera, known as ISERV, captured the Bow and Elbow rivers at their peak as they ravaged downtown. Here are some of the images, courtesy the people from Servir Global.

For comparison, we’ve overlayed “before” images from Google Maps. Just move the slider back and forth to see the difference.

1. Overall impact of the flood from downtown moving east to Inglewood Golf and Curling Club and south to Bonnybrook.

2. Calgary Zoo, at the confluence of the two rivers.

3. A closer view of the west end of the zoo.

4. Prince's Island Park and Eau Claire.

5. Flooding Elbow River turns Talisman Centre into an island and inundates Mission, Erlton and Roxboro.

6. Stampede grounds next to the Elbow River.

7. The Bow River over-runs the Inglewood Golf and Curling Club and comes dangerously close to crossing Deerfoot Trail.
