Five years ago, reconstruction began on the intake of the Hebgen Dam, which controls the flow of the Madison River. Now, the project is projected to be complete by the end of this summer.
“In 2005, analysis indicated a need for the intake to survive a maximum earthquake,” said Benjamin Cope, NorthWestern Energy’s project manager for the dam rehabilitation. “Then in 2008, the stop logs in the dam failed and we had an uncontrolled release, which accelerated the need to begin the project. Construction began in 2009.”
