The Union our local newspaper has an article with some insight from NID on El Niño events in Nevada County.
Remleh Scherzinger, general manager of the Nevada Irrigation District, noted the National Oceanic and Atmospheric Administration predicts a persistent and intensified drought for this region.
According to Scherzinger, two-thirds of the state’s water comes from the Sierra. That makes northern California’s rainfall key to the entire state.
The state’s Department of Water has an eight-station index for the Northern Sierra region. The average for that region is 50 inches a year, measured from October to September.
The region received 37.2 inches for 2014-2015. It got 31.3 inches from 2013-2014.
