As California's "once in a generation" drought continues, our reservoir water and groundwater reserves are at record lows.

Over the last few months, Getty photographer Justin Sullivan has visited Shasta Lake and Lake Oroville, both of which are at 30 percent full capacity, to document the receding water and exposed shorelines.

According to this week's U.S. Drought Monitor report, 58 percent of California is in the "exceptional drought" category — the most severe type possible — while 82 percent is experiencing an "extreme drought." As we previously explained in this post illustrating the categories, that's really bad.

It's unlikely to get better before it gets worse as forecasters continue to downgrade the chance of El Niño bringing much-needed rain this winter.
