NICASIO, CALIFORNIA - JANUARY 12: In an aerial view, the Nicasio Reservoir is seen at 100 percent capacity after a series of atmospheric river events drenched Northern California on January 12, 2023 in Nicasio, California. As several atmospheric river events bring record rainfall to California, reservoirs across state are seeing their levels rise following several years of extreme drought. Marin County's seven reservoirs are now at 100 percent capacity and other major reservoirs in the state are closing in on historic averages. (Photo by Justin Sullivan/Getty Images)
