Idaho charter captain requirements
Quick answer
What license do I need to run a charter in Idaho?
You need the federal USCG captain's license plus Idaho's Outfitters and Guides Licensing Board system: an Outfitter License for the business and a Guide License for each guide. Idaho explicitly licenses lake and reservoir guiding (its Power Boating and Unclassified Water categories) the same way it licenses river guiding.

Idaho charter license, in detail
Idaho requires both a business-level Outfitter License and an individual Guide License, issued by the Idaho Outfitters and Guides Licensing Board (IOGLB). Unlicensed outfitting or guiding is a crime under Idaho Code 36-2104. The license structure explicitly extends past rivers: applicants demonstrate qualifying experience by activity category, including Float Boating (three supervised trips per river or 500-plus commercial miles), Power Boating (fifty hours on the water section applied for), and Unclassified Water (one complete commercial trip per lake section), so lake and reservoir guiding is licensed the same way as river guiding, not left out of the system the way it is in Colorado.

Fish and game interplay
Idaho licenses fishing and hunting guiding under one board, the Outfitters and Guides Licensing Board, and its activity categories are built to cover lakes and reservoirs as well as rivers: a guide qualifies separately for Float Boating (whitewater rafting rivers like the Salmon and Snake), Power Boating (motorized guiding, qualified by hours on the specific water section), and Unclassified Water, which covers lake guiding such as Lake Pend Oreille, Priest Lake, and Dworshak Reservoir with a one-trip qualifying standard per body of water. This is a deeper lake/reservoir coverage than Colorado's river-only outfitter statute or Wyoming's historically hunting-focused system. Idaho Department of Fish and Game separately regulates the fishing itself (seasons and limits); a for-hire operator carrying paying passengers for hire on any of these waters still needs the federal USCG credential on top of the IOGLB license, which is a state business/guiding authorization, not a substitute for the federal one.

State vs federal water boundary
Landlocked jurisdiction: no marine seaward boundary. The federal USCG credential still governs for-hire carriage on navigable waters, including lakes and reservoirs such as Lake Pend Oreille, Priest Lake, and Dworshak Reservoir.

Idaho charter FAQ
Does Idaho license fishing guides on lakes, or only on rivers?
Both. Idaho's Outfitters and Guides Licensing Board covers lakes and reservoirs through its Power Boating and Unclassified Water guide categories, alongside Float Boating for whitewater rivers. This is broader than states like Colorado, whose river outfitter license by statute does not extend to reservoirs.
Do I need the federal USCG credential in addition to Idaho's outfitter license?
Yes. Idaho's Outfitter and Guide licenses are the state business and individual authorization to guide for pay. If you carry passengers for hire on navigable water, you separately need the federal USCG captain's license; neither license substitutes for the other.
