Weir Work Delayed at Lower Monumental

WALLA WALLA -- Installation of a removable spillway weir at Lower Monumental Lock and Dam will be delayed until fall, according to the U.S. Army Corps of Engineers. Temporary spillway weirs are designed to provide fish with an efficient, less stressful route while reducing migration delays.

Completion was slated for April 13, but general contractor Advanced American Construction of Oregon City, Ore., notified the corps that it would not meet the deadline. As it is almost time for juvenile salmon to migrate downstream, the project was pushed back to increase salmon safety.

In the meantime, the corps is putting in its traditional spill to provide safe passage for fish this summer.

Advanced American Construction was awarded the contract in April 2006 for around $15 million.
