Read the following selection and then answer the question.

Water. It's vital to our lives. It keeps us hydrated and clean, is essential for food production, and is even the focal point during a relaxing vacation at the beach or lake. But when there's too much, water can be devastating. On June 22, 2013 and the days following, floodwaters ravaged downtown Calgary in Alberta, Canada, and took over the area. More than 100,000 residents were forced to evacuate the "Stampede City" and nearby towns. In the midst of the disaster, a new NASA camera aboard the International Space Station (ISS), called the ISS SERVIR Environmental Research and Visualization System (ISERV), snapped 24 images of the flooded area. The ISERV team sent photos of the scene to Canadian officials to help with response and assessment.
