Fly fishing is an art that combines skill, knowledge, and a touch of finesse. One crucial aspect of this art is selecting the right fly patterns to match what is hatching in the area you plan to fish. Geography and seasonality comes into play with choosing your fly patterns. With the vast array of fly patterns available in the market, it can be overwhelming for anglers to decide which ones to invest in and it’s easy to over do it when shopping. However, by targeting key patterns and understanding the dynamics of the local fishery, you can not only save money but also increase your chances of success on the water. In this guide, we aim to highlight the best fly patterns for a given river. While not all encompassing, let this guide serve as a quick reference and jumping off point for starting your fly fishing kit.
