Olympic National Park spokeswoman Barb Maynes said Saturday that crews had drilled 35-foot-deep holes in the concrete over the past week that have been stuffed with explosives to blow out one of the few remaining sections of the once-210-foot-tall dam.
“We're really getting down very close to the bottom now,” Maynes said.
She did not know the width of the section on the far east side of the 87-year-old dam that will be removed today.
Today's blast will take out much of the remaining dam but not all of it, according to Maynes.
Maynes said crews with Barnard Construction, the Bozeman, Mont., firm contracted to blast away the dam, were scheduled to blast this portion of the dam Saturday but were unable to prepare for the explosion earlier in the week because of high winds.
They also were set back by cold temperatures that led to a portion of the drill breaking, Maynes said.
Removal of Elwha Dam 8 miles downstream from Glines Canyon Dam was completed in March 2012.
Blasting on Glines Canyon Dam resumed in January after shutting down in November to accommodate fish migration.
Demolition crews set off about 2,000 pounds of explosives packed into a concrete stub of the dam Jan. 26, reducing it from a height of about 55 feet to about 35 feet.
The next fish window will begin in May.
Glines Canyon Dam is being removed via controlled explosions as part of the largest river restoration project in U.S. history, a $325 million effort to restore 70 miles of the river to salmon and steelhead runs that were cut off by the early 1900s construction of Glines Canyon Dam and the 108-foot-tall Elwha Dam.
