Next time you are on a lake and the sun has set, look in different directions. You will note a silvery sheen to the surface in some directions and a darker appearance in other directions. Looking toward the W/SW will allow you to see the darker, slashing shapes of porpoising fish or the bubbling slurps as fish take your fly or insects. Just a slight edge in seeing activity. If you enjoy the squinting into darkness and the surprise of the hit, that’s ok too; look toward the darker sides. The picture above is pretty much last light, but for an hour or more before this, there is a point where fishing toward the lighter side has its advantages. The lighting will be influenced by the surrounding terrain of trees, mountains and hills. Experiment with it.
