I’ve camped there when it was less than 20% full.
At least the rains are washing the last remaining poison from when the EPA killed much of the tributaries. That lake is so huge, the last 5 feet to the top may never happen. Beautiful area.
The mountain drainage exceeds 1000 square miles.
They will have to significantly increase outflow to keep water from cresting over the top in this next storm.
The American River is adding another 60,000cfs where it joins IN Sacramento. Likely to also be increased.

My SIL’s family used to own property along the Sac River arm of the lake. They could only use a small portion of the property, as a camp. There were too many marijuana growers around, who let it be known that they should not stray far from their camp area. Forget about building a cabin.
