 On the Canadian side the raising of the dam was halted primarily by the extensive work by Curley Chittenden - logger turned environmentalist, who worked tirelessly to rally opposition to this additional flooding of the upper Skagit River basin.Ultimately a treaty was signed between the City of Seattle and Province of British Columbia to supply Seattle with the equivalent amount of power from other, existing dams in British Columbia in exchange for Seattle not raising the dam.The Skagit Environmental Endowment Commission was created at this time to oversee joint USA/Canada stewardship of the upper Skagit River watershed.
