Iowa DNR is surveying 2025 license purchasers using an angler diary approach. If you received the early invitation, please participate,
It’s a great way to help Iowa represent angler activity. There will be a more conventional, end of year survey in November, so you may receive an invitation later this year.
Rebecca Krogman, the new DNR Biometrician, shared this cool map (link) showing the locations of license purchases from 2025.
In the last survey from 2021, anglers from 48 states and four foreign countries fished for trout in Iowa.
Minnesota, Illinois and Wisconsin residents were the majority of non-resident trout anglers at 31%, 22% and 13% respectively, with the remaining 34% coming from other states or countries.
Nonresident anglers purchased 6,550 trout stamps in 2021, or 12.5% of all trout stamps purchased, a higher percentage than any of the previous nine surveys. The previous highest percentage of nonresident trout stamps purchased was 10.8% in 2016. Non-resident anglers accounted for 11.1% of the 2021 respondents, which is slightly lower than the 12.7% of non-resident trout stamp purchasers.
