North Umpqua River

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 2017 schedule of planned waterway maintenance which may affect flow in bypass reaches 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, equipment, personnel, construction and maintenance progress, and other issues. The dates listed are the approximate date of canal or powerhouse shutdowns, but ramping and flow changes may impact adjacent days as well. Note “fish flow” means sufficient flow to keep fish alive, generally 2-20 cfs depending on canal and season. Note also that high natural flows and unplanned shutdowns for emergency responses and brief maintenance events may occur at any time without advance notice. For details contact Rich Grost, PacifiCorp, 541-498-2617.  Version date 8-2-17.
