Clean Lakes Alliance hosted an event today to explain seasonal changes happening to Madison’s lakes.
A University of Wisconsin-Madison researcher is encouraging people to visit local lakes in May to witness an annual phenomenon that makes the water crystal clear.
Hillary Dugan, an associate professor at the Center for Limnology at UW-Madison, explained the science behind the seasonal clarity. In spring, a large bloom of diatoms, a species of phytoplankton, provides food for zooplankton, tiny organisms that then boom in population.
