One of the four large rubber bubbles forming west of the dam failed, for reasons that are still unknown. Tempe Police are investigating the breach.
Temp work to replace the bubbles on the past year because they were determined to achieve their life earlier than expected. Bridgestone, the manufacturer bubbles, made two of the four sections of the replacement of the west dam. But the city and its contractors have been working to replace the sections, but efforts were hampered in recent months, the upstream water flow from snow melt and rain in other parts of the state.
