Tuesday night, I decided to wade up the middle of Spring Creek and follow it through the upper Arb from its mouth at Upper Lyman Lake to see what I could find. As soon as I had left the glow of Carleton’s streetlights, my phone flashlight began to illuminate a beautiful community of native fauna, caught in the act of enjoying the spring season. As I waded through the icy water, I was struck by the number and diversity of fishes I found.
