|Matilija Dam, Feb 18, 2017|
flow 3,500+ cfs
|2-day rainfall totals Feb 18, 2017|
The storm of Friday, February 17, 2017 delivered 9-10" of rain to the Matilija Canyon watershed. Flows in Matilja Creek peaked at 4pm with approximately 7500 cfs (cubic feet per second) flowing over the dam. The Ventura River at Foster Park peaked over 20,000 cfs later that evening.
The hydrograph below shows flows in Matilija Canyon exceeded 3000 cfs for more than 48 hours. This is the perfect scenario for flushing the fine sediments from the reservoir to the ocean, as required in order to physically remove the dam. (See Matilija Dam stakeholders select local project)

Although much work remains until the project is ready, a storm like this will exceed that required for the eventual removal of Matilija Dam.
In the News:
“What it really demonstrates is the tremendous energy that the Ventura River has when we get these types of flood events,”
