Knowing what flies to use when is one of the keys to successful fly fishing. Thankfully, nature is a little predictable in this area. Through our extensive network of contacts and friends, we’ve collected an encyclopedic knowledge of fly hatching information. The pages that follow provide detailed fly hatch charts for each region of the country.
Fly hatch charts can help you pick out the appropriate flies for an upcoming fly fishing trip. However, they should never be taken as a guarantee of success but rather as a general guide to expected aquatic insect activity.
If there are any locations not included in this list, please feel free to let us know using the contact page and we’ll look into adding it.
