As documented on this blog, the storms of 2019 transported large quantities of sediment down the Ventura River following the Thomas Fire of December 2017. In February, a new sediment delta was observed in the Matilija reservoir. Recent observations of vegetation sprouting in the reservoir suggest deposition this year has significantly reduced the depth of the reservoir. Ventura County plans to survey and update the bathymetry in the near future.
