The LimnoTech Toledo Water Intake Buoy in Ohio was deployed the week after the 2014 water ban in an effort to better understand and detect HABs. The sensors track the wind and the waves, so that an occurring bloom can be tracked more efficiently and not sneak up on the citizens again. For more information, including a list of the sensors and their purposes as well as links to viewable data, check out the LimnoTech page on Toledo’s website.
In addition, there are two Sonde sensors in the lake, monitored through Michigan. While the LimnoTech sensors track movement, the Sonde sensors test the water quality and can detect an actual bloom. For more info, check the page on Toledo’s website.
