which was signed to kind of come up with an approach for preventing and resolving disputes over the use of shared waters. It was it established an international joint commission to help the two countries carry out its provisions. And at the time disputes over water, most notably on the Niagara River and the East Coast, were already creating tension along the border. So the treaty provided this framework to deal with these disputes. It held its first meeting in 1912 and it has worked over the last century plus to resolve more than 100 matters raised by the two federal governments. So the Columbia River Treaty more specifically came about during this era of hydropower expansion in the United States and Canada, which is sort of symbolized in the 1930s with the construction of the Grand Coulee Dam in Washington. And during about a 20 year period, more than a dozen large dams were built in the Columbia River Basin, mostly for hydroelectric power purposes. They also benefited flood control, navigation, and other irrigation projects. The construction of these dams had and continues to have a negative impact on the ecosystems of the Bayeson. For example, the completion of the Grand Coulee Dam eliminated salmon runs from the mainstream Columbia River and tributaries in British Columbia. So the specific impetus for the Columbia River Treaty was a major flood in 1948. The river was abnormally high due to deep snowfall and large rainstorms and it breached a dike in Randport, Oregon
