North Dakota Starts Draining Lake into Canada
------------------------------------------------------------------------
WINNIPEG, Manitoba - Despite Canadian fears of contamination, North Dakota began pumping water on Monday from its Devils Lake floodlands into a system that leads eventually into a commercial fishery north of the US border.
The US diversion plan has been a diplomatic sore point because of Canadian concerns the water could pollute Manitoba's Lake Winnipeg, the world's 10th largest freshwater lake and home to a C$25 million ($21 million) fishery.
North Dakota says the water from Devils Lake, which has swallowed up 90,000 acres of land over 12 years of higher than normal precipitation, is safe. But Canada fears the land-locked lake contains high concentrations of salts and other pollutants along with foreign fish and organisms.
The system diverts water through a canal into the Sheyenne River, which drains into the Red River, which empties into Lake Winnipeg.
Canada and the United States reached an agreement earlier this month on several modifications to prevent harm to the Canadian lake. But some critics in Canada were not appeased.
"We did our little modifications on a few things, so we're back in the operations mode," said Dale Frink, North Dakota's state water engineer.
"We'll run (the outlet) on and off until Nov. 1," Frink told Reuters.
The Manitoba and Canadian governments had pushed for a review of the Devils Lake project by the International Joint Commission, an independent binational agency set up to resolve cross-border water disputes.
But North Dakota said the review would take too long, and governments had already spent more than $400 million moving homes and building and repairing roads and bridges because of the flooding.
The Bush administration declined to refer the project to the commission, and pushed for the agreement that saw North Dakota add more rocks and gravel to its drain to keep fish and other organisms from leaving Devils Lake.
Scientists from both countries are studying water quality, and US and Canadian governments will design and construct a more advanced filter system based on the studies.
So far, biologists have not found any invasive species such as zebra mussels in the lake, but they are still waiting on results on fish viruses and parasites, as well as other organisms, said Dwight Williamson, manager of water quality at Manitoba's water stewardship department.
"Clearly, our preference would have been for all of these results to be in prior to operation," Williamson said.
