25 Major flood stage. Stage Road at San Gregorio Creek flooded and adjacent floodplain properties under 4 or more feet of water.
21 Moderate flood stage. Adjacent floodplain under several feet of water. Stage Road crossing is backwatered.
17.7 Minor flood stage. Flood waters inundate floodplain upstream of Stage Road crossing, mainly on left bank side (as looking downstream). NWS will issue a Flash Flood Warning if not yet already issued.
