California’s drought still persists through the rain.
Although Redding has received over an inch of rain today, the city still needs about 23 inches just to get back to our normal yearly rainfall.
It’s not out of the question for parts of the NorthState to receive that much rain in just one month.
Shasta Dam got nearly 40 inches of rain in December of 2002, Redding got nearly 15 inches of rain that year.
Two feet of rain anywhere in the world will cause problems, but California’s dam system is built for exactly this type of situation.
California’s climate is centered around this type of boom or bust rainfall.
The dams have made it possible for people to live in the Sacramento Valley without having to worry about flooding.
In the event of a huge rainfall event in December, Shasta Dam officials say they’ll likely hold all the water to try to raise the lake level.
In the event that the dam is filling too quickly, they’ll release more water after the rains have stopped.
That tactic of delayed release will keep the Sacramento River at a higher level for longer, but keeps the peak river stages lower.
