Boaters and beachgoers visiting the Chicago area this summer will have access to even more real-time data on lake conditions with a second nearshore environmental-sensing buoy that was launched in Lake Michigan on Tuesday, August 4, 2015.
 
The new buoy, located roughly four miles off the coast of Wilmette, Ill., relays information on wind speed, air and water temperature, wave height and direction, and other environmental characteristics from May to October each year.
 
Tom Palmisano, an owner of Henry’s Sports and Bait shop in Chicago, volunteered his boat and time to take out the anchor portion of the buoy.
 
“The buoy will be useful for anybody who does anything on the water,” said Palmisano, a longtime commercial and recreational diver. 
 
The Sheridan Shore Yacht Club in Wilmette donated use of their crane to lift the hulking sections — totaling over 600 pounds — into the water.
 
The TIDAS 900 Wilmette buoy is a joint project between Illinois-Indiana Sea Grant (IISG) and LimnoTech to help advance understanding of nearshore waters, alert the public to hazardous conditions in real time, and improve weather forecasts. Staff from Purdue University Civil Engineering also assisted on the project. This one is also equipped with a webcam enabling people to actually see the conditions on the lake.
 
“This is a tremendous leap forward,” said Ed Fenelon, a National Weather Service (NWS) meteorologist with the Chicago office. “Before this buoy, there was a data void in almost all of the nearshore area.” 
 
Data from the first buoy launched in 2012 off the coast of Michigan City, Ind., has already led to adjustments in wave forecast models and boosted understanding of fisheries and nearshore dynamics. 
 
Data from the Wilmette buoy will also be used to improve predictions of hazardous weather conditions and issue swim and small water craft advisories.
 
“To accurately forecast the future, you have to have a detailed measurement of current conditions,” Fenelon added. “This buoy will give us just that.”
 
Current lake conditions will be updated every 10 minutes and be available at the IISG Wilmette Buoy page.  The mobile-friendly sites highlight conditions of particular interest to recreational users, such as wave height, wind speed, and surface water temperature.
 
Along with graphs showing trends over recent time periods, this information will tell boaters and kayakers when it’s safe to be on the water and help anglers target specific species.
 
“We have talked with many different groups in the area, from anglers and boaters to scientists, and the response to the buoy has been overwhelmingly positive,” said Jay Beugly, IISG aquatic ecology specialist. “People are excited that this information is so easily accessible.” 
 
The Wilmette buoy was funded through the Great Lakes Observing System (www.glos.us), which is part of the National Oceanic and Atmospheric Administration’s (NOAA) greater Integrated Oceanic Observing System network. 
 
Information collected from the buoys is also fed into the National Data Buoy Center (http://www.ndbc.noaa.gov/) operated by the National Oceanic and Atmospheric Administration and the more localized http://greatlakesbuoys.org/Forecasters, researchers, and others can download raw historical data for Michigan City buoy ID 45170 or Wilmette buoy ID 45174 from any of these websites.

We are excited to offer the opportunity to propose a speaker or panel session during the 2026 Emerging Contaminants in the Environment Conference April 28-29.  The conference will feature traditional 15-minute presentations and a poster session on the latest in emerging contaminant research, policies, and outreach in the soil, water, and air.The deadline to propose a session is June 16, 2025.Learn more at the link in bio.
What Wild Things Will You Find in Your Watershed? Join us from April 22 to May 19 on iNaturalist for the Great Lakes BioBlitz! Participate in weekly challenges, view others' observations, and build community across the basin.How to Participate:-Register: Sign up on iNaturalist.-Observe: Explore your watershed and document the wildlife you find.-Engage: Share your observations and connect with fellow nature enthusiasts.
Join the Invasive Crayfish Collaborative for an exciting webinar featuring Purdue University master's student Izzy Paulsen. Izzy will share her mixed method study exploring how and why teachers use live crayfish and their interest in outreach. Her study draws from interview and survey data conducted in Great Lakes states. Register at the link in bio.
Deadline extended! The IISG program, in cooperation with the @nationalparkservice at @indianadunesnps and @UrbanRivers in Chicago, is offering two internship opportunities to support conservation policy efforts. Sea Grant’s national Community Engaged Internship (CEI) program aims to broaden participation in coastal, ocean, Great Lakes, and marine sciences providing training and mentorship to the next generation of scientists, decision-makers, and citizens. The program will do so by recruiting, retaining and engaging students in place-based research, extension, education, and/or communication that respects and integrates local ways of knowing.Applications due April 21.Learn more at the link in bio.
