Lake Cachuma’s surface sparkles in the afternoon sunlight, the water lapping gently against the concrete walls of Bradbury Dam. The 193,304-acre-foot reservoir in the Santa Ynez Valley provides water to much of Santa Barbara County. Today, it is mostly full at 88% of capacity. That’s a far cry from the situation about two short years ago, when the reservoir had dropped down to 31% full. However, the bucolic scene at Lake Cachuma today belies the fact that, after two wet years, the county has edged back into drought conditions, raising concerns about water supplies and fire danger. The southeastern half of the county is now listed as being in “moderate drought,” according to the U.S. Drought Monitor map. The northwestern portion has been tagged as “abnormally dry.”
