By John Fefchak August 4, 2023

In response to the Co-operator’s July 13 article, “Water strategy action plan launched”. During a press event on July 17, Manitoba Environment and Climate Minister Kevin Klein noted that, in 2013, Lake Winnipeg was designated the most polluted lake in Canada. He went on to say that, since 2016, the Manitoba government has been working

Cyanobacteria, also known as blue-green algae, can produce toxins that are harmful to livestock, wildlife and people.

Watch for blue-green algae in your livestock water supply

Deadly algae can thrive in livestock water sources during hot spells, but remote watering systems lower the risk significantly

By Jeff Melchior July 12, 2023

In over three decades as a veterinarian, Roy Lewis never saw a cow die from ingesting blue-green algae from an infected water source. But he still says it’s an issue ranchers should watch for. Why it matters: Manitoba has had a hot start to the summer with over two dozen days with daily highs above

Algae blooms can endanger livestock

Hot weather can promote blooms which can produce harmful toxins

By North Dakota State University July 6, 2021

Cyanobacteria, also known as blue-green algae, can produce toxins that are harmful to livestock, wildlife and people. The growth of this bacteria is aided by high temperatures. “The hot, dry conditions we are experiencing are perfect for the production of cyanobacteria,” says Miranda Meehan, North Dakota State University Extension livestock environmental stewardship specialist. Given the current conditions, producers and the public should

Alum a useful tool to combat toxic algae

The chemical has been used in the U.S. to clear lakes of algal blooms but hasn’t seen widespread acceptance in Canada

By Geralyn Wichers December 23, 2019

It’s no magic bullet, but aluminum sulphate can significantly reduce toxic algal blooms in lakes, American scientist John Holz told conservationists at a Winnipeg conference on December 3. “It is a common tool,” said Holz, whose company HAB Aquatic Solutions, has done 104 applications of the product, also called ‘alum,’ in the U.S. Holz spoke

A total of 885 fishermen and women registered for the Healthy Lake Committee ice fishing derby March 3 on Pelican Lake, near Ninette.

Nitrogen reduction not the path

Reducing how much nitrogen enters a lake has little impact on algal blooms, IISD researchers say

By Manitoba Co-operator Staff January 8, 2018

If you take the nitrogen out of the equation for lake algal blooms it turns out you really haven’t changed things at all. According to researchers at the Experimental Lakes Area, operated by Winnipeg’s International Institute for Sustainable Development, that’s because many of the algae responsible for the harmful blooms can turn around and fix

Researchers say the substances have been associated with  several health conditions

By Manitoba Co-operator Staff December 11, 2017

Manitoba’s largest lake is the host to potentially harmful toxins caused by cyanobacteria, more commonly known as “blue-green algae.” Researchers from the University of British Columbia, working with the Lake Winnipeg Research Consortium, were looking for a specific toxin called BMAA that’s been linked with conditions ranging from Alzheimer’s to Lou Gehrig’s disease. “Cyanobacteria blooms

Ontario watershed study shows overapplication of phosphorus

By GFM Network News, John Greig June 1, 2017

Farmers in one Huron County, Ont. watershed are applying almost exactly the nitrogen needed by their crops, but more than 30 per cent more phosphorus than is needed. University of Guelph researchers reached the conclusions by analyzing multiple years of data collected by the Ausable Bayfield Conservation Authority during in-person interviews with farmers in the

Better on-farm management would go a long ways towards solving the problem

There are two easily identifiable solutions to the Lake Erie algae blooms, said an American researcher, but success will require the co-operation of thousands of farmers. Jeffrey Reutter, a researcher at the Lake Erie island-based Ohio State University Stone Lab research station, has seen both the 1970s sewage-driven algae bloom, and the current blooms that
