California’s Rainy Season of 2016-17 Is Officially One for the Record Books

Until this year, the wettest year the “El Niño” year of 1982-83 stood as the Northern Sierra’s 8-Station Index wettest season on record, with an index of 88.5 inches. The average is 50 inches. To date, the current daily Precipitation for this year is 92.8 inches! The eight sites the Department of Water Resources uses in its Northern Sierra eight-station index are scattered across the Sacramento, Feather and American river watersheds. Those basins are the source of most of the water captured by the Central Valley Project and State Water Project and are key to the state’s annual water supply.
