National Water Model Hydrograph
Official NWS streamflow forecasts are produced by NWS hydrologic forecasters for river gauge locations using hydrologic models which are calibrated to that location. This process considers additional guidance and information, including local expertise and experience, to produce the best forecast possible. The NWM output provides supplemental guidance to NWS forecasters and should not be considered an official NWS river forecast.
Flood Impacts
- 25 - expect major flooding from Canby to the Willamette River. Historically, businesses along Hwy 99E in West Canby have been threatened by high water at this point. Flooding in the community of Barlow can be expected at this and higher stages, along with flooding of numerous homes and agricultural land.
- 24 - expect widespread flooding of agricultural land and secondary roads. Historically, buildings and other structures in the lower sections of the river from Canby downstream to the confluence with the Pudding River begin to flood at this point.
- 23 - expect flooding of low-lying agricultural land from Canby downstream to the confluence with the Pudding River. Some secondary roads and a few structures may begin to flood.
