According to the U.S. Drought Monitor, 82 percent of the state of California currently falls in the "Extreme Drought" category. The years-long dry spell has tapped groundwater reserves and left reservoirs at record lows. Shasta Lake and Lake Oroville are both down to 30% of full capacity, exposing steep shorelines that were formerly under hundreds of feet of water. Marinas are crowding into ever-smaller coves as the water recedes, and ramps and roads no longer reach the shoreline. Getty Images photographer Justin Sullivan traveled to a number of these reservoirs last month and captured dramatic images, evidence of the severity of the water crisis in California.
