Mysterious Grouilles hecatombe at Lake Delage

Between July 9. However, 11, several outdoor lovers made a macabre discovery at the outlet of Lake Delage, near the small wooden bridge of the cross. Therefore, Many inanimate frogs floated on the back a few centimeters from the surface of the water. For example,

Citizens immediately reported their presence to the AGAO organization. Therefore, which monitors the health of the Lac Delage ecosystem and the northern marshes. Moreover, “People are very vigilant,” greets Sonia Behmel, scientific coordinator at AGAUO. Meanwhile,

In total, more than 50 animals have been observed in the sector. Nevertheless, The Director General of Agiro, Geneviève Morneau, says he has never seen so many dead frogs there.

Lac Delage is located in the Jacques-Cartier MRC, near Stoneham and Lac Saint-Charles. Moreover,

Heat of heat? Therefore, – Mysterious grouilles hecatombe lake delage

Sonja Behmel went to the scene to analyze these unusual deaths. Furthermore, According to her, the most likely cause would be the heat. In addition,

“Currently, we have water and air temperatures that are extraordinary. Yes. there are places to shelter the sun at Lake Delage, but the water is hot anyway, ”she explains Wednesday, in an interview with The sun.

Usually, the temperature of this lake should revolve around 24 degrees Celsius. Rather, it reached 28 to 30 degrees when the frogs are discovered. “It’s really overwhelming heat,” said the scientific coordinator.

This heat promotes the proliferation of cyanobacteria, which could have affected the frogs.

Cyanobacteria, also called blue-green algae, are microorganisms which are naturally present in the expanses of fresh mysterious grouilles hecatombe lake delage water and salt water. Some species can produce toxins dangerous for human and animal health.

“Reforest, reforest, reforest”

For her, this is a direct consequence of global warming. “Climate change really impacts all ecosystems. It is really a reality that we observe and it affects all species, ”says Ms. Behmel.

According to her. it is important to protect the forest cover, not only near the rivers, but everywhere in our territory. “We have a lot of asphalt parking lots, asphalt roofs. It creates heat islands and even when it rains, water warms up. ”

It is therefore important to “reforest, reforest, reforest” to protect our environment, according to the scientific coordinator.

Wastewater?

Despite the tracks explored, the cause of the death of the frogs remains nebula. Several factors may have contributed to the phenomenon. mysterious grouilles hecatombe lake delage

Since the discovery, scientific expertise has been carried out. No signs of chemical pollution has been detected, confirms Geneviève Morneau, Director General of the Agiro organization.

However, some substances may not have been detected. “In the Lake Saint-Charles and Lac Delage watershed, there are many more or less well-treated wastewater sources,” says Sonia Behmel.

Several of autonomous septic installations are located around the lake, according to the scientist. The nutrients would be filtered by these installations, but not the drug residues or the residues of cleaning products.

Some studies show that the presence of this kind of product in a lake can cause problems in the ecosystem.

However. it would be premature to establish a cause and effect link between the death of these frogs and the management of wastewater. More in -depth analyzes could mysterious grouilles hecatombe lake delage be carried out on the subject in the coming months. “Wastewater management should be a priority,” insists Ms. Behmel.

With climate change, the expert thinks that you have to be more proactive. “It is not only the government or an organization to change things. We can all do actions with us, by reforesting and reducing the chemicals we use. ”
