Water supply a concern on both sides of border

The stakes are high: In a valley with the least water per capita of all water basins in Canada, there are many who want their interests to be top priority, including residents of the U.S. and trans-boundary native bands.

The stakes are high: In a valley with the least water per capita of all water basins in Canada, there are many who want their interests to be top priority, including residents of the U.S. and trans-boundary native bands.

For the opening of this week’s international Water Science Forum in Osoyoos, Osoyoos Indian Band Chief Clarence Louie said: “The Okanagan Nation wants to work with you to ensure we can always swim in these waters and eat the fish in these waters.”

But he was blunt as well: “Either you invite us in the door or we’re going to kick down the door.”

By way of explanation, he pointed to history and warned, “We’re not going to just stand on the sidelines again. We won’t be silent. We will have as much of a say as anyone else in the future.”

He told of the opening in the last century of the Grand Coulee Dam on the Columbia River, where the First Nations were invited to don their traditional regalia and attend the opening ceremony, even though they had not been consulted when the white man decided to erect that barrier to fish passage up the river and into the Okanagan Valley, prohibiting the salmon from migrating.

He said that on Thursday, the valley’s chiefs will meet in Westbank to discuss the water that flows down the valley and across the border.

He noted that the international boundary is an imaginary line dividing the Okanagan peoples, so that today the Colville Tribes are in the U.S. and the Okanagan Nation are in Canada, where once they were one.

And, when Chuck Brushwood spoke for the Confederated Tribes of the Colville Reservation, he added: “We are all salmon people and salmon need water.”

Louie explained that the salmon “indicate whether we’re doing our job. We have to pay attention. They’re an important part of our lives.”

Plants and animals require good water and they are the first to suffer, he said. “It all starts with water.”

Okanagan MLA John Slater agreed it’s all about the water, and also that there’s only one water source serving an area from Vernon to Oroville, Wash.

“We need to control it. We need drinkable water to take care of our future. Water is the number one restriction on growth. If we screw this up we’ll be in big trouble,” Slater warned.

From south of the border, Washington Senator Bob Morton noted they’re already having difficulties with water supply in his state.

Some of the challenges include the need for more power production and dams to store B.C.’s spring runoff for agricultural production on the U.S. side of the border, he said.

“By 2050, we’ll need to double agricultural production to feed our own nations and the nations of the world. Fresh water is our greatest asset. It’s more precious than gold,” he added.

Management of water use in the entire Okanagan Valley should become part of the orders governing Osoyoos Lake, so that needs for water south of the border can be met, believes at least one scientist reporting to the International Joint Commission.

“Basin-wide water management must be used to meet demands. Solutions don’t stop at the border. We have to look at managing upstream uses,” said Michael Barber, a professor at Washington State University and director of the Washington Water Research Center.

In addition, he suggested that alternative sources of water be researched, since Osoyoos Lake is a small storage lake with little room for variance in water level without impacting recreational use or shoreline residents.

“Osoyoos Lake has limited storage capacity for all the demands,” he commented, in proposing that flows be the basis for orders governing the trans-boundary waterway instead of lake level.

In making the recommendation, Barber said he looked at what volumes of water would be needed by 2040 to meet the demand for irrigation, domestic and in-stream/fish needs.

During drought years, he noted that 90 per cent of the demand is for fisheries requirements.

Osoyoos Mayor Stu Wells, who is also chair of the Okanagan Basin Water Board, said such a proposal concerns him, particularly when in southern Washington officials are looking at diverting water from the Columbia River to replace shortages resulting from aquifers that are drying up, leaving farmers short of water.

Another one of Monday’s speakers, Jim Mattison, a consultant with Urban Systems, recommended that the commission amend its definition of what is a drought year, when water level requirements are more flexible, since in half of the past 24 years, a drought has been declared.

In four of those, it was actually rescinded, he noted, but nonetheless, normally droughts don’t occur that frequently. His review was conducted jointly with water engineer Don Dobson and fisheries biologist Brian Jantz.

Further complicating the discussion about Osoyoos Lake water levels is the impact the freshet from the Similkameen River has once it enters the Okanagan River downstream from Osoyoos Lake.

In some high-water years, it can actually cause water to back up into Osoyoos Lake.
