The final snowpack measurement in the eastern Sierra Nevada Mountains showed levels well above average after winter’s unrelenting storms in California. The snowpack is an important measurement for water managers who determine how much water Southern California can expect to received from the Los Angeles Aqueduct, a system of channels and tunnels that stretches hundreds of miles from the eastern side of the 400-mile long Sierra Nevada Mountain range to Los Angeles. Snow in the mountains melts in spring, running off into the aqueduct and other water delivery systems around the state.  Based on the snowpack survey, the Los Angeles Aqueduct will flow at or near full capacity for much of the year.
