Since 2013, fisheries staff from the Iowa Department of Natural Resources has collected data on Iowa lakes by using specialized equipment connected to computers aboard a boat. The software records lake depth along with information on what type of material is on the lake bed (sand, gravel, muck) and, if aquatic vegetation is present, the height and density of that vegetation. This data is used to generate more accurate maps for anglers.
