The Iowa Department of Natural Resources (DNR) is conducting a statewide walleye fishing challenge from May 1 through June 30.

Anglers will have the chance to win weekly prizes while also contributing to fisheries research, helping improve walleye fishing in the state.

The Iowa Walleye Challenge uses the MyCatch mobile app to record the length of a fish. Participating anglers take a picture of the fish on a measuring device using the app. Once the fish is reviewed by the catch team and meets the rules, it automatically appears on a live leaderboard where anglers can see who is in the lead to win prizes.

Participating anglers are encouraged to report all the walleye they catch in May and June through the MyCatch mobile app. The mobile app maintains anonymous location data, so angler’s secret spots stay secret. DNR fisheries biologists will use the generalized lake and river catch data entered to assess and manage walleye populations across Iowa.  

“Results from year one were very promising,” said Jeff Kopaska, DNR fisheries research biometrician. “Iowa anglers can expand the data available, simply by reporting their walleye catches.”

Anglers can find details about the contest rules, prizes, and how to register for the Iowa Walleye Challenge at There is a $25 fee to enter the tournament.
