Images captured by a satellite launched from Vandenberg Air Force Base four years ago show the dramatic difference in water levels for two Central Coast reservoirs after recent rains. The U.S. Geological Survey posted a Landsat 8 image from Dec. 29, showing low water levels for Lake San Antonio in Monterey County and Lake Nacimiento in both San Luis Obispo and Monterey counties. California’s drought left Lake Nacimiento only 22 percent full as of late last year.
