USA, AZ/Tempe: Historic Salt River Dam After Heavy Rains Royalty-Free Stock Image

This is the historic rubber dam, now substituted by a metal dam. The dam dams up Rio Salado/Salt River in Tempe. Usually the river bed is almost completely dry, but on September 8, 2014 torrential rains filled the reservoir (Tempe Town Lake) to the brim and had to be released into the river bed. This was regulated by a rubber dam, which wascontrolled by an operating system that inflated or deflated rubber tubes. The tubes were bolted to concrete slabs. To protect the rubber from the heat of the sun, a pedestrian bridge (with sun sails above the slabs) was built to shade the dam; Hayden Butte (A-Butte) and Hayden Flour Mill in the background of the photo.
