🪪 Do I need a fishing license to fish at Three Mile Reservoir?

Fishing in Iowa requires a valid state fishing license for anglers. Licenses include resident and non-resident, annual and short-term options, available online or at license agents statewide.

In Iowa, no fishing license is required for anglers under 16 or residents 65 and older. A few other exceptions worth knowing:

  • Free fishing days — most states designate 1–2 weekends a year where anyone can fish without a license

  • Tribal waters — tribal members fishing on tribal land operate under separate tribal regulations

  • Private ponds — landowners fishing their own water typically don't need a license

Non-residents usually pay more for a license than residents. Some species also require an extra stamp or endorsement on top of your base license.
