At the request of the Iowa Department of Natural Resources (IDNR) fisheries biologist, a geophysical resistivity survey was performed by the IDNR Geological and Water Survey (IGWS) to evaluate the nature and extent of lake bottom sediments along a small identified area on the north shore of East Okoboji Lake. The area in question is east of the Highway 71 bridge that intersects East and West Okoboji Lakes and adjacent to Mau Marina (Figure 1). The goal of the request by Mike Hawkins, fisheries biologist, was for IGWS staff to define the age of lake bottom sediments at the site. IGWS observations are based on a geophysical survey of the area, observations of soil samples from the site and observations from cores taken from several nearby lakeshore borings on adjacent West Okoboji Lake.
