Aging dam above Douglas called 'catastrophic' threat
DOUGLAS A pair of engineering firms contracted by the state warn that cracks in the 112-year-old concrete LaPrele dam, along with deterioration in its geologic foundation, could result in catastrophic failure.
Such an event would threaten people and infrastructure downstream, including the town of Douglas, and likely destroy the Ayres Natural Bridge Park directly below the dam, as well as two Interstate 25 bridges, the Wyoming Water Development office said during a tour last week.
This is more than an irrigation district matter, Water Development Office Director Brandon Gebhart said. Its a hazard.
Rehabilitating the dam might be impossible, according to Gebhart. Instead, the office and its governing citizen commission is considering building a new dam directly below the existing structure. The commission will consider seeking funds to develop a complete engineering study for a project that could exceed $50 million.
