Summary: Crews repairing streamgages and measuring Santa Maria River upstream and downstream of Twitchell Reservoir releases

As forecasted, the most recent precipitation did not cause additional high flows. Most field office staff are conducting routine activities and preparing for the next storm forecast mid-week. Predictions are for another widespread rain event this week, with high precipitation in the Sierras and along the Central Coast, and up to 4-6 inches possible in the mountains of LA to San Diego.

The Twitchell Reservoir on the Cuayama River is releasing high flows into the Santa Maria River due to high water levels. Two crews of two each are measuring the Santa Maria streamgages upstream and downstream of the outflow and fixing those gages. 2 crews for a total of 3 people are repairing other streamgages.

This week, the ID WSC sent two experienced people for an extended time to help the Santa Maria Field Office measure high flows and repair damaged gages.
