Updating local reservoir status information

This post was originally published on this site

Halfway through January, we published an article looking at how California reservoirs were doing after the “atmostpheric river” dumped a series of storms on our heads.

Here is an updated version of the table of local reservoirs from that article:

Name of Reservoir % of Capacity % of Historical Average % of Capacity % of Historical Average
Cachuma
data from January 14
85% 132% 98% 136%
Casitas
data from January 13
37% 51% 45% 60%
Castaic 54% 70% 57% 71%
Diamond Valley 61% 84% 60% 81%

The green percentages are as of today, March 1.

This from the California Cooperative Snow Survey for the Southern Sierras as of January 16, 2023, with updated information in green as of February 28.

Description
Number of stations reporting 32 29
Average snow water equivalent 32.1 inches 42.0 inches
Percent of April 1 average 142% 162%
Percent of normal for this date 288% 186%

The current local seven-day forecast calls for rain today, then sunny for the rest of the week.
