Permanent repairs, upgrades scheduled for Hebgen Dam gate
Date: Jun 27, 2022
Butte, Mont. – June 27, 2022 – Permanent repairs and upgrades to the release gate at Hebgen Dam will begin later this summer and are expected to be complete by mid-September.
A stem coupling on the release gate failed on Nov. 30, 2021, causing the gate to partially close. An investigation, called a Root Cause Analysis, was completed. The findings and corrective actions were reviewed and approved by the Federal Energy Regulatory Commission, the federal licensing authority for NorthWestern Energy’s Missouri-Madison Hydroelectric Project. The work taking place at Hebgen Dam will implement the corrective actions identified through the Root Cause Analysis.
Outflow from Hebgen Dam will continue over the spillway until work is completed on the dam gate.
