Tempe Town Lake stitched panorama. The lake itself fills the bed of the Salt River. The original dam was controlled with multiple inflatable bladders. One winter produced so much spring run-off that all sections of the dam had to be lowered to prevent up-river flooding. It is a pretty rare event. A few years later one of the sections exploded due to the Arizona sun causing the rubber to rot sooner than expected, the entire lake was drained in order to replace all of the bladders. They took the opportunity to install a bridge across the bladders for easier access between the north and south sides of the lake.
