The Dalles Dam Lock Closure Extended
The Oregonian, January 3, 2011
The U.S. Army Corps of Engineers has extended the closure of The Dalles Dam navigation lock by five days, officials said Monday.
The lock at Columbia River mile 192 closed Dec. 10 to replace the downstream miter gate and had been scheduled to reopen March 18. But setbacks in the fabrication of the new gate as well as added welding led to delays.
The corps of engineers is replacing gates at The Dalles, John Day and Lower Monumental dams, shutting down all river traffic, as well as doing maintenance and repair work at other locks in the Columbia-Snake navigation system.
