Here is a map that I obtained from the CNRFC on January 18th. The orange circles indicate River gages that are at monitor stage.

The dotted orange link in the above graphic is the bottom of the monitor stage. The data is revised several times a day so what you see if you go the url will be different from what is displayed above.
I do know from reading storm reports from the NWS San Diego whose storm report may be found here ,and the NWS Hanford CA (their storm report is on this website) that there were several reports of flash flooding and debris flows. I do not if there was any property damage from these flash floods and debris flows. I know from the CBS station in Los Angeles that residents in and near the Holy burn scar in the Lake Elsinore area of Riverside County were under evacuation orders on January 17th, go here to read the article. Mandatory evacuation were downgraded to voluntary orders yesterday. I believe that the voluntary evacuation orders were lifted later on January 17th.
