Bypass Flows

The Rogue River flow line is no longer in service. Flow information is provided in the table below.

Rouge River

The portion of the Rogue River natural channel between North Fork Dam and the Prospect No. 2 Powerhouse is commonly called the North Fork Rogue Bypass. Releases from the dam provide flow through this natural channel at all times of the year. Flows may vary due to a number of factors including weather, upstream flows, and dam operations. The flows reported here are recorded at a gage near the OR Highway 62 bridge, approximately 0.3 miles below the dam.

Disclaimer: PacifiCorp is by no means promoting or inviting the public to participate in whitewater boating activities in the Rogue River bypassed reach. These water management data are estimates of river flows. Please beware and use caution, as actual river flows may be vastly different because of operational changes at the dams or due to weather conditions. Remember: These are estimates only and are subject to extreme change without notice.

Important Notice:

Several planned outages will occur in 2018 for maintenance of project generating units. The outage dates include May 23, 2018; July 20, 2018; and September 10, 2018 through September 28, 2018.

These outages may result in the release of more flow than the required minimum flow in the bypassed reach of the North Fork Rogue River between North Fork Dam and the powerhouses. During the outage from September 10, 2018 through September 28, 2018, the full inflow of the North Fork Rogue River to North Fork Reservoir may be released to the bypassed reach below North Fork Dam. As disclaimed above, dates of the outage and flows released from the dam are subject to change without notice.
