Little Goose lock reopening delayed until April 11
Repairs at the Little Goose Dam navigation lock have delayed its reopening until April 11, according to the U.S. Army Corps of Engineers.
The dam was originally slated to reopen March 20 with the rest of the Columbia and Snake river system locks. Its reopening has been delayed twice.
Operational testing of the north gate revealed that the pintle heel was not replaced in the correct position under a previous contract, the corps said in a press release. The north gate’s quoin blocks will need to be machined to correct the deficiency.
Surveying was performed on the south gate, confirming the south pintle heel was also installed out of position under the previous contract. Corrections were made, and the gate is being moved into place to verify the alignment, according to the corps.
The pintle heel is a part of the bottom hinge component, said Gina Baltrusch, corps spokeswoman. Quoin blocks are the thick, vertical pieces of metal on the outside of the gate that run from top to bottom, creating the water-tight seal between the gate and the wall.
The corps will shave roughly one-sixteenth of an inch off the quoin block so it will seal properly, Baltrusch said.
“We regret the impact to our navigation stakeholders caused by this additional delay in reopening the lock at Little Goose,” project manager Jason Williams said in the press release. “We are doing all we can to restore safe, reliable lock service as quickly as possible.”
Columbia Grain in Clarkston, Wash., is one of the companies that uses the river system to ship grain to Portland for sale to overseas customers.
Assistant vice president Randy Olstad said he supports and trusts the corps to make sure the repairs are done right.
“It’s frustrating at this point, but the river system is extremely important for our business,” he said.
His company had time to prepare for the downtime, but is eager for the dam to be repaired, Olstad said.
Customers have been understanding so far, he said.
“We’ve done our job, I believe the corps is doing their job,” he said. “This is just an unforeseen circumstance we wish they would have caught earlier, but did not. That’s water under the bridge. We’ve just got to deal with it.”
Olstad declined to estimate how much the delay will cost the company.
“It’s more of our reputation, saying what we’re going to do and doing what we’re going to say,” he said. “I think that’s more on the line than anything.”
