Nearshore buoys deployed off Waukegan and Winthrop Harbor

Lake Michigan now has two new buoys that monitor lake conditions in real-time. Placed about a mile offshore in Illinois waters—close to Waukegan and Winthrop Harbor—each buoy will measure air and water temperatures, wave and wind conditions, and water currents every 20 minutes while deployed. The buoys are also equipped with webcams that transmit an image and video once per hour during daylight hours. Illinois-Indiana Sea Grant will host the most recent data and images on their program website, while data will be managed by Great Lakes Observing System (GLOS).

Ethan Theuerkauf and colleagues from the Illinois State Geological Survey (Prairie Research Institute, University of Illinois at Urbana-Champaign) and the Illinois Department of Natural Resources Coastal Management Program have been working to deploy these buoys for several years. “We plan to use the buoy data to study the drivers of erosion along the Illinois shoreline,” said Theuerkauf, a scientist with the Illinois State Geological Survey and an adjunct professor at the University of Illinois at Chicago. “It is a bonus that so many boaters and swimmers can also use the information.”

“It’s great to have two more systems that will help scientists and weather forecasters understand what’s happening in the Illinois and Indiana waters of Lake Michigan,” said Jay Beugly, an aquatic ecology specialist with Illinois-Indiana Sea Grant, who helped place the buoys in the water on July 19 and is the main support for the Illinois-Indiana Sea Grant real-time buoy program.

Ed Verhamme, a project engineer with LimnoTech, Inc., designed and custom-built these buoys for application along the Illinois shoreline. “These buoys are closer to shore than other buoys in Lake Michigan, which helps scientists better understand how waves and currents affect the shoreline, but also required us to use a different type of buoy”, said Verhamme who also joined Beugly and Theuerkauf during the buoy deployment.

As of July 23, 2018, data from the two new buoys can be found via the GLOS data portal and the National Data Buoy Center by searching buoy numbers 45186 (Waukegan) and 45187 (Winthrop Harbor). These buoys were supported by a NOAA Coastal Zone Management Projects of Special Merit Grant.

      Hi there – thanks for this message. As we mention in the story, funding for this particular buoy came through a NOAA Coastal Zone Management Projects of Special Merit Grant. The main investigator on that grant is Ethan Theuerkauf. Community support is essential to getting new buoys, but each group that manages a buoy has a different approach to funding them. There are also different permitting processes and mechanics for actually getting buoys in the water in different parts of the Great Lakes. In some cases, like the South Haven buoy, local communities or tourism boards pull together money to fund buoys each year. In the case of the buoys Illinois-Indiana Sea Grant supports completely, we tend to write grants to support them. But our program is focused on southern Lake Michigan. My suggestion is to reach out to the Regional Science Consortium (presqueislesp@state.pa.us). You can see data from buoys they support here: http://wqdatalive.com/public/55. Since they already work in eastern Lake Erie, they may have some ideas for what you need to do to put buoys in the water over there, and may have some more specific names for who to contact. If you don’t have good luck over there, I may have some other ideas for who to connect with. But I’d try them first.
