Lake Cachuma — a major water source for Santa Barbara County — finally filled to capacity early Sunday morning.

The county Public Works Department reported that the reservoir in the Santa Ynez Valley reached the 753-foot elevation — the point at which is considered 100% full — at 3:30 a.m.

Water has been streaming through the gates at Bradbury Dam for more than a week, as reservoir managers made room for runoff from recent major storms.

At the peak, they were releasing about 7,000 cubic feet per second (CFS) from the lake, but that number was down to 684 CFS on Sunday.

Although officially full, the lake level is continuing to rise, as there is another foot of “freeboard” on the dam gates, according to Matthew Young, the county’s Water Agency manager.

At capacity, Cachuma holds some 193,135 acre-feet of water, which supplies South Coast entities including the city of Santa Barbara and the Goleta Water District, as well as downstream users in the Santa Ynez and Lompoc valleys.

The two impoundments upstream from the lake — Gibraltar Reservoir and Jameson Lake — are both also full and spilling water into the Santa Ynez River, which feeds Cachuma.

With recent heavy rainfall, Santa Barbara County overall has received 140% of its average annual rainfall to date. The city of Santa Barbara is on the high end, at 179% of normal.

National Weather Service forecasters are calling for dry conditions this coming week, but say another wet-weather pattern is likely beginning next weekend.

Daytime highs this week are expected to be around 60 degrees, with overnight lows in the upper-40s.
