Among the various projects taking place at Gavins Point Power Plant, generator unit number three was recently dewatered to allow project crews to inspect the draft tube for damage caused by cavitation and make the necessary repairs. Cavitation repairs in the draft tube for unit three will continue through mid-March. Additional maintenance and rehabilitation projects are also underway at the Gavins Point project including replacing three power transformers and rehabilitating the spillway’s tainter gates. Work will move to unit two for annual generator maintenance, to install new un-watering and drain valves, to install a new motor control center, and replace switchgear equipment.
A stalled front brings record rainfall to the Front Range of the Colorado Rocky Mountains. The runoff brings a surge of water through canyons and foothills and into major population centers of central Colorado.
But, this surge of water happened only in a virtual environment.
During the week of Aug. 19, several employees from the U.S. Army Corps of Engineers, Omaha District participated in a safety exercise focused on Cherry Creek Dam and Reservoir near Denver, Colo. – or more to the point, in the middle of the Denver metropolitan area.
In mid September, a wet monsoonal pattern stalled along the Front Range of the Rocky Mountains bringing heavy rains to the foothills west of Boulder. The resulting flooding impacted roads, bridges and other infrastructure, with rivers carving new channels and eroding riverbanks. Major roadways in the Estes Park area sustained severe damages with limited alternatives to access these areas for repairs.
The U.S. Army Corps of Engineers, Omaha District activated its Emergency Operations Center Sept. 12, in preparation for the anticipated requests for assistance during and following the resulting flooding.
Calls also began to flood the Omaha District’s Denver Regulatory office located on Chatfield Dam near Littleton, Colo.
