Spirit Lake, Iowa (RI) — State officials have started a series of surveys to chart the population of fish in lakes and streams around the state. Andrew Carlson is a Department of Natural Resources biologist and the fisheries manager for the Spirit Lake district.
The DNR conducts these surveys in the spring, summer, and fall, going to different depths and using three sampling techniques.
In the spring, crews typically find a lot of blue gills and crappies in shallow water, but hoop netting in the summer goes deeper, and they typically find more catfish in Iowa lakes in the summer. Go to www.radioiowa.com to find a link to all sorts of data from these fish surveys around the state that anglers can search to evaluate fishing spots.
