I think a lot of serious photographers avoid this lake because of its limitations, despite its fame and beauty. To begin with, it is forbidden to approach its shores, as a perimeter of wooden barriers plastered with signs makes clear in no uncertain terms. Therefore, you're stuck back in the trees and can either shoot through them or else choose one of three openings that provide a clear shot of the lake.
Then there's the matter of light versus water volume. When the water level is low, some of the beautiful yellow lake bottom and lots of boulders are revealed (as you see here). The time of year when the water is low, however, is also when the sun is setting further south; so to get the mountains in the shot, you either have to shoot right into a high sun or else shoot when the sun is down. In the summer the water in the lake rises all the way up to the trees, which makes the lake look less interesting. Ah well, "fools rush in where angels fear to tread"...
