Shasta Lake Rises 10 ft. in One Day

This is some great news for our area from Dr. Roy Spencer.

The latest in a series of Pacific storms hit California yesterday with high winds and over 6 inches of rain at Shasta Dam. A number of mountain stations that feed the reservoirs in N. California, which are at very low levels from the continuing drought, have registered over 10 inches of rain in the last week.

With yesterday’s heavy rains, Lake Shasta rose a spectacular 10.6 feet in one day, which added over 130,000 acre feet of water volume to California’s largest reservoir. That’s enough water to fill 65,000 Olympic size swimming pools.

The following graph shows that there is still a long way to go to reach even normal water levels on Lake Shasta:

Nevertheless, it also shows how the reservoir can recover in only one year, as it did from the 1976-77 dry period to the 1977-78 wet period, the result of rains from weak El Nino conditions.

The current El Nino conditions in the Pacific are contributing to the current wet and stormy period, which will need to continue before we can even begin to talk about the drought being over.
