Bliss Dam Spillway Repair
Delivering design-build innovation to protect Bliss Dam, control erosion, and ensure safe and reliable operations
IMCO Construction completed remediation work at a hydroelectric dam on the Snake River, near Bliss, Idaho. The facility, built in 1950, required improvements to an area downstream of the spillway to prevent erosion. This design-build project focused on safety and coordination with dam operators at an active facility.
The work included underwater concrete construction and crane hoisting. Design began in early 2022. After a two-year permit delay, construction started in 2024 and was completed in February 2025.
