Maintenance Work Will Restrict Traffic over Hells Canyon Dam Aug. 3–6

Visitors crossing Hells Canyon Dam from either direction should expect delays while Idaho Power crews remove stop logs.

OXBOW, Oregon — Visitors intending to cross Idaho Power’s Hells Canyon Dam Aug. 3–4 should plan to do so between 10:30 a.m. and 12:30 p.m., Mountain Time. Motorists could also experience delays of up to 45 minutes Aug. 5–6.

Idaho Power crews will be removing large beams called stop logs from the dam and moving them to a storage area. Stop logs are used to control water flow through the dam to allow for maintenance.

The work will require a crane to be on the dam Aug. 3–4, preventing any traffic from crossing from 7 a.m. to 10:30 a.m. and again from 12:30 p.m. to 5:30 p.m. both days. A single lane will be open for two hours beginning at 10:30 a.m. Pedestrians will be allowed to cross during the road closure.

On Aug. 5–6, the road across the dam will be open, but traffic could be delayed by up to 45 minutes while the stop logs are being loaded and unloaded. All Idaho Power operations in Hells Canyon are conducted on Mountain Time.

Located 21 miles downstream of Oxbow Dam, Hells Canyon Dam is the third and last project in Idaho Power’s Hells Canyon Complex. It began generating electricity in 1967 and has a nameplate generating capacity of 391,500 kilowatts.
