This lake is fairly crowded, and for good reason. It has many inlets, including the North Sacramento River, the McCloud River, the Pit River, and some creeks. The one outlet is the Lower Sacramento River, which makes that river to the south of the lake so huge (in width). It is best to go in the fall.
Shasta Lake, also popularly known as Lake Shasta, is a reservoir in Shasta County, California, United States. It began to store water in 1944 due to the impounding of the Sacramento River by Shasta Dam, the ninth-tallest dam in the U.S.

This is the second largest dam in the U.S. (and the dam with the world's greatest overflow spillway), and provides electricity to the majority of the North Central Valley, and flood protection to the whole Central Valley. It is worth visiting just to enjoy the view from the top, but is not for acrophobes.
