Troutline started in the Western US (California, Colorado, Idaho, Montana, Wyoming, Oregon, Washington, Utah, and New Mexico) and has begun expanding beyond it, into North Carolina's Southern Appalachians, the Missouri Ozarks, Pennsylvania's limestone and freestone country, the Upper Midwest with Michigan's spring-fed trout rivers, and now the Northeast: New York's Catskills, the birthplace of American fly fishing, and the cold tailwaters of the Delaware. In Canada, it covers Alberta, British Columbia, New Brunswick, Newfoundland and Labrador, Northwest Territories, Nova Scotia, Ontario, Prince Edward Island and Quebec. In New Zealand, it covers Bay of Plenty, Canterbury, Hawke's Bay, Manawatū-Whanganui, Marlborough, Otago, Southland, Tasman, Waikato, Wellington and West Coast. The roadmap below shows what's next.
