Residents can buy a daily fishing license but not a three-day salmon-steelhead permit. Residents and nonresidents alike may buy a "license entitling a person to fish in the waters of the state on a day-to-day basis." A resident daily fishing license costs $11.50 plus $5 for each additional day purchased at the same time - $12.75 and $6 for nonresidents - but a daily fishing license holder can't add a steelhead-salmon permit to their license. Resident anglers must first buy a season fishing license for $25.75 to buy a steelhead or salmon permit for $12.75. Nonresidents, however, may buy a three-day combined fishing license and salmon or steelhead permit for $37.50. The rules do not allow Idaho residents to buy the nonresident three-day salmon-steelhead license.
