Upper Skagit Watershed

Construction of Ross Dam

The construction of Ross Dam forever changed the landscape of the Upper Skagit Watershed. The proposal to erect the fourth step of the dam--often referred to as High Ross Dam--led to the international agreement that created the Skagit Environmental Endowment Commission, and established the current parameters for the management of the Upper Skagit Watershed and the purchase of electrical power by the City of Seattle from the province of British Columbia.

The following images show the site of Ross Dam from pre-construction to completion of the third step.
