The historic breaching of Condit Dam in the White Salmon River ends more than a dozen years of planning and legal wrangling. The carefully orchestrated blast opened up a PacifiCorp-owned dam that has blocked the river since 1913. It also entirely drained Northwestern Lake, the reservoir behind the dam.
UNDERWOOD — The lower White Salmon River is laced with woody debris that “look like shish kebabs facing upstream ready to spear you,’’ said the rafting guide who on Wednesday made the first trip down the stream since the breaching of Condit Dam.
“They are scary looking,’’ said Mark Zoller, owner of Zoller’s Outdoor Odysseys, a rafting company based in BZ Corner. “They are a kayaker’s nightmare.’’
Zoller, 47, is a Hazel Dell native and 1982 Columbia River High School graduate. His company is the largest of the commercial rafting outfits on the White Salmon.
He was hired to go down the river as part of a study of siltation following last Wednesday’s breaching of the 125-foot-tall dam 3.3 miles up the river.
Zoller and 12 others, using three rafts and a kayak, put in Wednesday morning about .75-mile downstream of the Condit site. They took out at the mouth of the river at Underwood.
“How the debris sits in the river is crazy,’’ Zoller said. “There are logs everywhere. It looks like they floated down, hit the sandy bottom, wedged in, got cemented in place for now, and are sticking upstream. It’s a huge danger.’’
Zoller said the river is changing daily.
“Yesterday, there was an island at the mouth of the river. It’s gone today.’’
The river is 4 inches deep in many places. Four times on Wednesday Zoller had to get out of the raft and drag it through water less than 2 inches deep.
“The river is moving fast,’’ he said. “An engineer explained to me the math, but all the particles in the water make the river flow faster than normal.’’
Rafts normally don’t move fast in 4 inches of flow, but they did on Wednesday, he added.
The material on the river bottom is an intermittent mix of mud, sand and gravel. Zoller said he was surprised at the amount of gravel.
At spots, the shoreline could be walked with ease. Elsewhere, the rafters sunk to their knees in the muck.
The river downstream of Condit is closed to rafting and fishing. PacifiCorp, operator of the Condit Dam, issued a statement on Tuesday reiterating the danger of the White Salmon River.
“It’s such a quick-changing environment,’’ Zoller said. “People could see something on YouTube and think it’s OK to get on the river and then really get themselves screwed up.’’
Zoller noted the regular BZ Corner reach of the river is open for rafting.
Commercial trips for the former Northwestern Lake reach and downstream of Condit must wait until the entire dam and coffer dam have been removed, perhaps by late summer 2012, he said.
“People will have to be patient and give the river time to clear itself and the contractors time to remove the dam,’’ Zoller said.
