In western states like Colorado, fly fishing is a hobby to many, a religion to others. Western anglers live for the opportunity to spend the day casting for a greenback cutthroat in an alpine lake, or even a rainbow from a nearby creek. While we anglers tend to focus their attention on the fish and the flies, sometimes we take the water for granted. In the west, water is a precious resource that demands careful management. From the perspective of an angler and student of Environmental Studies at CU Boulder, Fishing Western Waters will explore the science, policy, and values fishing the waters of the American west.
