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
- 66 - Extensive and severe flooding can be expected from above Klamath Glen to the Pacific Ocean including the towns of Klamath and Klamath Glen and US Highway 101. The forecast level is over the top of the levee. Any persons living or working in areas protected by the levee should take appropriate action and move to higher ground.
- 65.5 - Extensive and severe flooding can be expected from above Klamath Glen to the Pacific Ocean including the towns of Klamath and Klamath Glen and US Highway 101. The forecast level is at the top of the levee. Any persons living or working in areas protected by the levee should take appropriate action and move to higher ground. High tides and strong, onshore winds amplify effects.
- 65 - Severe flooding is expected in the delta area, particularly US Highway 101 in the vicinity of Requa Road, the access road to Klamath Glen, and secondary roads. The forecast level is within 0.5 feet of top of levee. Any persons living or working in areas protected by the levee should take appropriate action and move to higher ground. High tides and strong onshore winds will amplify flooding effects.
