ASO completed April 2018 California snow surveys in the San Joaquin, Tuolumne, Merced, and Kings river basins last week.  The ASO team delivered data products for San Joaquin and Tuolumne within one week of completing data acquisition for each basin.  The snow depth, snow albedo, and snow water equivalent data from these surveys will be used by California Department of Water Resources and local water agencies to make key water supply decisions for the remainder of the year.
