Michigan City Buoy

The Michigan City buoy serves many audiences. For the National Weather Service (www.weather.gov), buoy data are used to forecast wave and weather conditions; observe current conditions, and change forecasts when observations are not the norm as expected. Recreational users of the lake also benefit from the data provided by the buoy. Boaters, anglers, paddlers and surfers use the data to make decisions about their personal safety, i.e. assess conditions before traveling out for the day. Charter fisherman use the data to make decisions about the safety of their customers and crew, and also which locations will be good for fishing depending on the current wind, wave and temperature conditions. The Michigan City Port Authority (www.mcmarina.org) and the Lake Michigan Indiana Department of Natural Resources office (www.in.gov/dnr/water/3592.htm) played pivotal roles in helping deploy the buoy and anchor. The buoy was first deployed through a grant from Illinois-Indiana Sea Grant. A grant from the Indiana Department of Natural Resources Coastal Management Program (www.in.gov/dnr/lakemich) allowed for the addition of the temperature chain.
