NASA released a satellite image over the weekend that showed what a large swath of California look like during the winter, when the Sierra Nevada was heavily covered with snow. A second image shows what the same region looks like now. It’s a classic good news, bad news story. Reservoir conditions are good throughout virtually all of California. In April, the snow level in the Sierra was 162 percent of average. The reservoirs will be well stocked for a long period of time.
