R&M was a sub-consultant with responsibility for geotechnical investigations and analysis, and surveying and mapping for the dam and powerhouse, and civil engineering design of the ancillary features. R&M also provided design support for the main dam, spillway and tunnel. The project included a concrete-faced, 170’ high rockfall dam with a 19,000’ long power tunnel conducting water to an above-ground powerhouse to with two Pelton turbine generating units, small diversion dikes and permanent maintenance facilities.
Today, Bradley Lake is the largest of seven hydroelectric facilities in Alaska. It provides a clean, affordable alternative to fossil fuels to six electric utilities throughout the state.
