Southern California's Largest Reservoir Refilled After 3-Year Drought

California's largest reservoirs and lakes are filling up after an extremely wet winter, with Southern California's Diamond Valley Lake and Northern California's Lake Shasta seeing significant increases in water levels. While the state has seen twice as much precipitation as the entire water year of 2021-22, the drought is not yet over, with only 36% of the state still in a drought as of March 23. Officials are emphasizing the importance of investing in facilities that capture and store water to prepare for a "hotter, drier future."
