For a behind-the-scenes look at how 50 percent of Seattle's power is generated, visit the Boundary Hydroelectric Project, just one mile south of the Canadian border. Boundary Dam, which is nestled in the foothills of the Selkirk Range, arches between two massive rock cliffs. Its gates retain the flow of Washington's second largest river, the Pend Oreille (say Pond-er-ray).

The utility won the "National Eyes on Wildlife Award" for teaming up with the Colville National Forest to assist in the development of Flume Creek Mountain Goat Viewing Area. Seattle City Light manages the Boundary Project and six other hydroelectric plants in Washington state, providing the lowest cost, most reliable and greenest electricity in urban America.

Security Note: With heightened security concerns, access may be limited. Photo ID is required for all adults and some areas of the project are restricted.
