(Lewis) The Iowa DNR is working on a series of projects to enhance your fishing experience.
Essentials for a fishing trip in the past have probably included a pole, some bait, and maybe a boat. In the future that list might expand to include a specialized fishing map provided by the DNR. Lewis Bruce with the Iowa DNR says,
“Our ultimate goal in fisheries is to shorten the time between bites. A lot of the fish in lakes aren't spread out evenly, you have pockets where you cach fish and places where you don't, so being able to figure out where these fish are located is part of this project.”
Bruce says his research has focused on small lakes. The projects can take up to five years to complete and involve several passes across a lake with hydro acoustic equipment to locate fish. The passes through the lake also determine sediment depth and pinpoint various landmarks that may attract fish.
"Each one of those points is distinguished by a number and that number corresponds to the same number in the legend which has GPS points on it. So you can either take the contour map out and look at landmarks or you can take these GPS coordinates and download those into your GPS unit to go straight to these structures that concentrate fish."
Several maps are already available on the web. They can be viewed on the fishing page of the iowadnr.gov website.
