Progress in Lake Restoration Science
The media almost always gets the story wrong about effective methods to eliminate cyanobacteria blooms in lakes (otherwise known as blue-green algae or harmful algal blooms (HABs). The actual track records for the most talked-about methods are astoundingly poor, about “0 wins” vs “5000 losses” since the U.S. Clean Water Act was passed in 1970. Usually the articles talk ...
