Latest Snowpack Measurements Show California Water Supplies in Decent Shape

Despite a slow start, California’s snowpack has started to catch up to historical averages for this time of year across the central and southern Sierra Nevada. The northern portion of the mountain range — responsible for roughly 30% of Southern California’s water — continues to lag behind.

The northern Sierra is at 61% of normal, while the central Sierra is at 93%. The southern Sierra is at 114%. Large amounts of Southern California’s water come from the Sierra Nevada.
