Lakes across the country are struggling with harmful algal blooms, low oxygen, and declining fish populations. While these problems are often obvious at the surface, many management practices are based on misconceptions that don’t address the real causes. Instead of solving the issue, they often make lakes even sicker. Chemical Treatments: A
While invasive zebra mussels consume small plant-like organisms called phytoplankton, Michigan State University researchers discovered during a long-term study that zebra mussels can actually increase Microcystis, a type of phytoplankton known as “blue-green algae” or cyanobacteria, that forms harmful floating blooms. Zebra mussels can filter out the Microcystis with other particles, but then they spit
A national environmental organization labeled the Raccoon River one of the country’s most endangered because of toxic algae and nitrates. Des Moines Water Works called it a “catastrophe,” as the Raccoon is the major source for drinking water for a half-million Iowans. Des Moines Water Works, after dumping as much as $250,000 a year into
It’s a familiar sight to residents living on the shores of Kitsap Lake in Washington: each summer, around the beginning of June, a bright green algae begins to creep across the water. These blooms can be harmful to people and pets and have forced closures of Kitsap Lake and its beaches every year for the
Spraying chemicals can be dangerous to the environment in many ways. But for Floridians, they can contribute to harmful algae blooms and damaging releases along the coast. There are other ways to remove invasive plant species that may not require chemical spraying. James Douglass, an environmental scientist at Florida Gulf Coast University says the other
An aquatic weed harvester was used to remove macroalgae from Georgica Pond in New York from 2016 through 2018 and on a limited basis last year, an effort to inhibit harmful algal blooms, including toxic cyanobacteria, or blue-green algae. Approval has just been granted for the the mechanical harvester to be operated from June to
Efforts to restore Georgica Pond are proving to be successful thanks in part to the help of an aquatic weed harvester. Georgica Pond has been invaded by toxic cyanobacteria, or blue-green algae, in recent years, which can cause serious health problems. For the second consecutive year, the foundation has leased an aquatic weed harvester to
Blue-green algae, technically known as cyanobacteria, are microscopic organisms that are naturally present in lakes and streams. Typically present at low number, blue-green algae can quickly become abundant in warm, shallow, undisturbed surface water rich in nutrients like phosphorous and nitrogen. Some blue-green algae produce toxins that could pose a health risk to people and
