The Iowa Department of Natural Resources (DNR) is partnering for a second year with MyCatch by Angler’s Atlas to conduct a statewide walleye fishing challenge starting May 1 through June 30. The Iowa Chapter of the American Fisheries Society has joined as a research partner for the 2023 challenge. 

The Iowa Walleye Challenge uses the MyCatch mobile app to record the length of a fish. Participating anglers are encouraged to report all the walleye they catch in May and June through the MyCatch mobile app. DNR fisheries biologists will use the generalized lake and river catch data entered to assess and manage walleye populations across Iowa.   

Anglers will have the chance to win numerous local prizes, worth over $6,000, in addition to $5,000 in statewide weekly prizes. Anglers who sign up for the catch photo-release tournament by April 24 are eligible to win an Early Bird drawing for a $50 gift card from Kwik Star. 

“Results from year one were very promising,” said Jeff Kopaska, DNR fisheries research biometrician. “Angler groups and local fishing businesses are excited to pitch in and help with this walleye fishing challenge. Fleet Farm is donating over $1000 for the weekly Most Walleyes caught prize and is also providing digital coupons for all participants.”
