During the 2017 Eclipse half the lake was eclipsed and the other half not. You could see Mt Hood lit up orange while the forest to the south went dark. Absolutely surreal. Lots of tourists on the east bank of the lake in designated camp spots and lots of transient locals on the west bank in the “Dispersed” (free) areas. Tons of cougars, there are prints all along the West Bank. At night you can hear them walk by your tent and growl. Really pretty walk, while the north bank of the lake is the prettier side, you can only see Mt Hood from parts of the south bank. Love that the lake looks like a bird on maps ;)
