About IdentaFly

We built IdentaFly because we like sharing what we know. Hatch timing, fly patterns, river conditions—honest information helps people spend less time guessing and more time fishing. There will always be quiet stretches people keep to themselves; the part we care about is the learning: bugs, water, and flies, in plain language.

The three of us live and work around Denver and get on the water when we can. We're not trying to sound important—mostly we're anglers who write code and tie flies and want the tools we wished we had at the vise and on the bank.

Fly tying, patient on the water

We poke at hatch charts, pattern photos, and gauges because we use them ourselves. If something is wrong or confusing, tell us; we'd rather fix it than polish the wording.
