About Rathbun Lake
Fishing & license
Iowa fishing license
Residents and nonresidents under 16 years of age can fish without a license. There is no general senior fee exemption, but Iowa residents age 65 and older may buy a discounted Lifetime Fishing License ($61.50) and Lifetime Trout Fee ($65.00). Children under 16 may fish for trout without paying the Trout Fee if they fish with a licensed adult who has paid it and they share the adult's 5-trout daily limit. · Fishing is open year-round for most species in Iowa — annual licenses run the calendar year and expire January 10 of the following year. A few species have restricted seasons, notably paddlefish (Feb. 1 - April 30); announced trout-stream stockings run April through September, though trout may be fished all year with a paid Trout Fee.
