The Columbia River Treaty, an international agreement governing the flow of water between British Columbia and six U.S. states, will be 55 years old this year. It has not aged well. The river springs from the Columbia Icefield in the Rocky Mountains of B.C. and winds 1,930 kilometres through the Northwestern United States – Washington, Oregon, Idaho, Montana, Nevada and Wyoming. No other river in North America spills more water into the Pacific Ocean.
The agreement reached between the U.S. Bureau of Reclamation and the Canadian province of Manitoba sets up a team with Canadian representation to oversee treatment and monitoring of the river water, and among other duties help develop an emergency response plan. The team also is to have representatives of the state and federal governments south of the border, and is to meet at least once a year.
