Denver Water prepares for spillway construction

DILLON – Construction is imminent at the Dillon dam.

Denver Water officials have accepted bids for construction and will recommend the board of water commissioners approve a contract at their meeting Wednesday, said Jim Weldon, dam safety engineer.

Weldon said engineers are recommending the approximately $2 million in improvements be completed by Moltz Constructors and Engineering Constructors – two companies working together in a joint venture.

If the contract is approved as recommended, Weldon said construction could begin in the first or second week of July.

Though most of the work should be completed by the end of this year, Weldon said the contractor will work through the winter and into next spring to complete the cleanup. The entire project should be done by May 1, 2003; it is not expected to interfere with next summer’s water storage levels.

Prior to this year’s low water levels, Denver Water officials expected they would need to lower the water levels to below 9,011 feet for the construction. According to Denver Water’s Web site, the water level sits at 9,017 when the reservoir is full, but water experts said they don’t expect the water levels to rise higher than they were Tuesday, at 8,992.49 feet.

Contractors will be removing deteriorating concrete from inside the reservoir’s spillway and replacing the concrete with a steel liner. Weldon said he hopes the new liner will last several hundred years.

The Dillon Dam Road and the bike path will not be closed during the construction, though Weldon said there might be some occasional short closures to let the trucks in and out.
