Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and
fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or

About "Mystery Creeks": If you recognize one of these, you already understand why I'm keeping it a secret. I'm not as strict as some anglers about hiding where I fish, mostly because I don't expect to substantially affect fishing pressure on already well-known or simply unpopular waters. But there are some gems where I don't want to add a single unfamiliar bootprint to the mix, due to the fishing, their wild character, or keeping a friend's secret. They're all "Mystery Creek" here—even the lakes.
