Osoyoos resident Doug Eisenhut last week accused water managers of flooding Osoyoos and causing millions of dollars in damage, choosing to benefit Kelowna over Osoyoos.

Eisenhut, the retired owner of Eisenhut Insurance, charged that officials should have started to lower Osoyoos Lake in January, as they were doing with Okanagan Lake.

The exchange at a public meeting on May 15 to discuss the flood situation was one of the more heated ones of the evening.

Most of the more than 100 people attending politely listened as officials from the Town of Osoyoos, the Regional District of Okanagan-Similkameen and the Government of B.C. explained the situation and answered questions.

Some audience members expressed frustrations with lack of information and with the inconvenience of evacuation, but the tone was mostly civil.

Eisenhut said officials should have known in January there would be flooding problems because of high snowpack levels.

“We knew that in January,” he said. “You lowered (Okanagan) Lake in January. Why didn’t you start lowering ours? That’s the question.”

The comment drew applause from some members of the audience, but it also highlighted the communication gap between some frustrated members of the public and the officials and experts.

“In January, February, March, we had an opportunity to at least keep our lake the level it was,” said Eisenhut. “You raised it, and now we get the flood, millions of dollars of damage. Did you sacrifice Osoyoos for Kelowna?”

Many of Eisenhut’s remarks in an 11-minute exchange were directed at Shaun Reimer, the B.C. official who oversees operation of dams on the Canadian side of the border, including the dam where water exits Okanagan Lake at Penticton.

Reimer explained that a high snowpack doesn’t necessarily translate into historic flooding on the scale of the 1972 floods. In other years, there have been high snowpacks, but no floods, he said, while acknowledging that the risk increases when snowpacks are high.

But much of the response to Eisenhut came from Brian Symonds, who sits on the International Osoyoos Lake Board of Control, a body under the Canada-U.S. International Joint Commission (IJC).

Armed with a slideshow of graphs and charts from government websites, Symonds tried to explain how the laws of physics affect rising and falling lake levels.

Symonds and Reimer at times appeared frustrated when their explanations seemed to fly over the heads of some audience members.

“I’m going to try to explain it again,” said Symonds when he stepped up to respond to Eisenhut. “Obviously I didn’t do a very good job last time and I hope this will make more sense.”

Symonds explained that the gates at Zosel Dam in Oroville, which regulate the outflow from Osoyoos Lake under normal conditions, have been “freeboarding” or wide open since March 26.

On that date, the level of Osoyoos Lake was at 910.32 feet above sea level.

The Zosel Dam is operated by the Washington State Department of Ecology based on rules established by the IJC.

“That was everything you could do possibly on Osoyoos Lake back on March 26,” said Symonds.

Even recently, flows from Okanagan Lake were fairly steady and Osoyoos Lake was within the comfort zone.

It was only when the Similkameen River started rising that the balance of inflows and outflows on Osoyoos Lake was upset, he said.

“We might like to be able to magically make the water disappear,” Symonds said. “The only way to get it out of the lake is to have the gates (at Zosel Dam) open and the elevation of the lake drive the water out.”

Officials let water out of Okanagan Lake in the winter months, lowering that lake’s level to provide capacity for anticipated snowmelts.

“If the water had not been let out of Okanagan Lake earlier, it would’ve been a lost opportunity with nothing gained by the people in this room,” said Symonds.

Eisenhut wasn’t persuaded.

“You lowered the big lake, you lowered Penticton’s Lake, and you raised ours,” he argued. “That was a man (made) decision and I think we are in an economic crisis year and your disaster fund only pays 80 per cent because you chose to obliviate Osoyoos. I think we should get 100 per cent of recovery, and not 80 per cent, because it was chosen to flood this area as opposed to hold the water back in Kelowna and flood there.”

Symonds tried to explain that with the nature of the channel at the outflow from Osoyoos Lake and the dam gates wide open, it would have been impossible to let more water out of the lake.

“You physically couldn’t do it,” said Symonds. “It’s fantasyland to think that it could’ve been down that low at (that) point in time.”
