Flood Impacts & Photos Collapse

77 Major Flooding. Willowside Road inundated and adjacent vineyards under many feet of water.
74 Moderate 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 Minor Flooding. Ewok Trail begins to flood. NWS will issue an Urban/Small Stream Advisory, if not yet already issued.
62.5 Monitor stage. Flapper valve on upstream right bank side (north side) inundated at this stage and may become blocked. Valve serves to drain adjacent low-lying vineyards, so runoff may accumulate at an accelerated rate on adjacent floodplains due to possible valve blockage or inoperation. NWS may issue a Flash Flood Watch, if not yet already issued.
