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
- 50 - Major Flooding. Major agricultural flooding on both sides of the river; local roadways on or near floodplain likely impassable; up to 10 feet of standing water on floodplain. Water has reached the top of the Highway 128 bridge wing wall on the west side and all but the highest portions of the bridge remain above water.
- 46 - Moderate Flooding. Agricultural floodplain lands may be as much as 5-6 feet under water, with inundation reaching the Highway 128-River Road-Moody Lane insection and the northeast Highway 128 bridge approach. NWS will issue a Flash Flood Warning, if not yet already issued.
- 39.7 - Minor Flooding. Water may have begun to inundate the lowest floodplain locations on the left bank (east) side of the river. NWS will issue an Urban/Small Stream Advisory, if not yet issued.
