Statewide Iowa – Over 2,000 updated fish structure locations and 215 lake outline maps have been added to the Iowa Department of Natural Resources (DNR) website.

Anglers can upload the locations of fish structures to their fish finders and GPS units to easily find brush piles, rocky reefs and gravel spawning grounds. DNR Fisheries staff and partners, such as county conservation staff and fishing clubs, strategically place fish structures in Iowa lakes to attract fish for anglers. Fish hide in these structures throughout the year.

Since 2013, DNR Fisheries staff collected data on Iowa lakes using specialized equipment connected to computers aboard a boat. The software records the depth of the lake along with information about the type of material on the lake bed (sand, gravel, mud) and, if aquatic vegetation is present, the height and density of that vegetation. This data is used to generate more accurate maps for anglers. Each map includes depth contours, boat ramp locations and other amenities.

Find more information about a specific structure such as GPS coordinates on the interactive fishing atlas or a downloadable GPX fish structure file from the Fishing Maps Web Page. These tools are updated annually as new content becomes available.
