The Wisconsin Department of Agriculture, Trade and Consumer Protection will be using a low-flying helicopter towing a magnetic sensor to measure the depth to bedrock in areas of northeast Wisconsin. Depending on the weather and flight conditions, this surveying will begin in early January with the helicopter flying over Brown, Calumet, Fon du Lac, Kewaunee, Manitowoc, Sheboygan, and Door counties. As for Door County, the area surveyed will include most of the county south of Sturgeon Bay and the canal. It will fly in a grid pattern with half-mile spacing between flight lines. By updating depth-to-bedrock maps, the project will reduce the financial burden on private landowners to verify existing maps. It will also enhance understanding of below ground properties in order to improve water quality. The results of this survey will be made public once available.
