What floods at each level
From the National Weather Service, highest first.
- 77 ftMajor Flooding. Willowside Road inundated and adjacent vineyards under many feet of water.
- 74 ftModerate Flooding. Water levels reaching underside of bridge deck at Willowside Road. Further rise in water levels will cause backwater effects at the bridge with waters seeking alternative routes around bridge with possible build up and overflow of roadway. NWS will issue a Flash Flood Warning, if not yet already issued.
- 70 ftMinor Flooding. Ewok Trail begins to flood. NWS will issue an Urban/Small Stream Advisory, if not yet already issued.
- 62.5 ftAction Stage. Flapper valve on upstream right bank side (north side) inundated at this stage and may become blocked.
