North Umpqua River flows

The flows represented by this gage station are in the North Umpqua River's Wild and Scenic Reach downstream of the North Umpqua Hydroelectric Project and Boulder Creek (a wilderness stream).

Real-Time flow data for this site is available from gage station 14316500 funded by PacifiCorp and managed by the USGS.

Forecasted flows for a nearby tributary, Steamboat Creek, are provided by NOAA's Northwest River Forecast Center.

Tentative 2026 schedule of planned waterway activity which may affect flow in bypass reaches or trigger a fish salvage at the North Umpqua Hydroelectric Project. Maintenance has been planned to occur during the Settlement Agreement preferred periods to the greatest extent possible. Dates are tentative and can change without notice due to weather, access, equipment, personnel, and other issues. The dates listed are the approximate range when flow changes are anticipated, but flow management may impact adjacent days as well. During some outages it may be possible to keep “fish flow” in the waterway, which means sufficient flow to keep fish alive, generally 2-20 cfs depending on the waterway, season, and weather. Note also that high natural flows and unplanned shutdowns for emergency responses and brief maintenance events may occur at any time without advance notice.

Note that Lemolo and Toketee lakes are actually hydro project reservoirs, but their ‘geographic map name’ is ‘lake.’
