California relies on a network of reservoirs that provide water to municipalities, industry, agriculture, and the environment.
A new water year began on October 1 and water managers are hopeful that it will be wetter than last year. The 2018 water year was warmer and dryer than the previous year with April 1 statewide snowpack adding up to just 58 percent of average, compared to 159 percent in 2017. Despite the decrease in precipitation, most major reservoirs were able to remain at or above average thanks to carry over storage from 2017. The lone exception continues to be Lake Oroville, which completed spillway reconstruction by DWR’s November 1 target date. Despite the newly upgraded dam infrastructure, water managers have stated that they will continue to manage the reservoir more conservatively than normal as the emergency spillway continues to be fortified with concrete.
