The portion of the East Fork Wallowa River between the Wallowa Falls Dam and the West Fork Wallowa River is commonly called the East Fork Wallowa River Bypassed Reach. Releases from the dam provide flow through this natural channel at all times of the year. Flows vary throughout the year due to a variety of conditions including weather, upstream flows and dam operations.
Real-time flow data for the East Fork Wallowa River Bypassed Reach is available from U.S. Geological Survey (USGS) gage station 13325000 funded by PacifiCorp and managed by USGS.
