Information: Ross Dam, originally called Ruby Dam, was built in three stages between 1937 and 1949, and currently stands 540 feet (165 m) tall. A fourth stage of construction was planned for the dam; however, in 1984 Seattle City Light made an electricity-purchasing agreement with British Columbia which delayed any further expansion of the Ross Lake Dam for 80 years. The lake and dam are named after James D. Ross, the superintendent of the Seattle City Light’s Skagit River Hydroelectric Project, which built the dam.
Miscellaneous Info

The U.S. portion of Ross Lake is in the Ross Lake National Recreation Area. North Cascades National Park is adjacent to the west and south, while the Pasayten Wilderness is east of the lake.
