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 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 this rubber dam, which was controlled 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.
