Upper Skagit Watershed

Skagit Basin Aerial Photographs

Seattle City Light conducted an aerial photographic survey of much of the Skagit Basin in July 1977. The survey was undertaken when the Federal Power Commission authorized the construction of the fourth step for Ross Dam. The raising of the dam would have raised the level of Ross Lake to the 1725 foot elevation, an increase of more than 100 feet. This would have had a profound effect on the rivers and creeks that feed the lake. The survey documented the forest cover, the topography, the courses of the creeks, and other natural features of the basin.
