In summary, the conversation discusses the issue of a severe algae bloom in Lake Erie caused by phosphorus pollution. The bloom has resurfaced after a decrease in the 1970s and may be related to a rainy spring and invasive mussels. The conversation also mentions the positive impact of the zebra mussel invasion on water clarity and fish populations. However, the issue of phosphate pollution from sewage sludge application on no-till corn fields is also raised.

How do we fix this?​

The green scum shown in this image is the worst algae bloom Lake Erie has experienced in decades. Such blooms were common in the lake’s shallow western basin in the 1950s and 60s. Phosphorus from farms, sewage, and industry fertilized the waters so that huge algae blooms developed year after year. The blooms subsided a bit starting in the 1970s, when regulations and improvements in agriculture and sewage treatment limited the amount of phosphorus that reached the lake. But in 2011, a giant bloom spread across the western basin once again. The reasons for the bloom are complex, but may be related to a rainy spring and invasive mussels.

Wait...

There's life?

In Lake Erie?

This is bigger than the Mars rocks!

Agreed!

I was born and raised in Milwaukee, along the shores of Lake Michigan, and Lake Erie has long been the shame of the Great Lakes.

Anyways, here's a nice song (and notice that it contains the lines: "and farther below Lake Ontario takes in what Lake Erie can send her":

Lake Erie is an example of an invasice species producing a postive result. The zebra mussel invasion effecitvley filtered water so much that the lake became clear and cleaner and fish populations are doing very well. The algal blooms cited here have been attributed phosphate pollution resulting from to winter application of sewage sludge on no-till corn fields. Spring snow melt carries phisphate into the lake.
 

What is causing the toxic algae bloom in Lake Erie?

The toxic algae bloom in Lake Erie is primarily caused by excess nutrients, such as phosphorus and nitrogen, entering the lake from various sources including agricultural runoff, sewage treatment plants, and stormwater runoff. These nutrients fuel the growth of harmful algae, leading to the bloom.

What are the potential health risks associated with the toxic algae bloom?

The toxic algae bloom in Lake Erie can produce harmful toxins, such as microcystins, which can cause skin irritation, respiratory problems, and liver damage if ingested. These toxins can also contaminate drinking water and harm aquatic life, leading to potential economic and environmental consequences.

What measures can be taken to prevent or mitigate the toxic algae bloom in Lake Erie?

To prevent or mitigate the toxic algae bloom in Lake Erie, it is important to reduce the amount of nutrients entering the lake. This can be done through better management practices in agriculture, upgrading sewage treatment plants, and implementing green infrastructure to reduce stormwater runoff. Additionally, reducing the use of fertilizers and properly disposing of pet waste can also help reduce nutrient pollution.

How can the public help address the issue of toxic algae bloom in Lake Erie?

The public can play an important role in addressing the issue of toxic algae bloom in Lake Erie by being mindful of their actions and how they may contribute to nutrient pollution. This includes properly disposing of waste, reducing fertilizer use, and supporting efforts to improve water quality. Additionally, individuals can get involved in local initiatives and organizations working to protect and restore Lake Erie.

What are the long-term solutions for addressing the toxic algae bloom in Lake Erie?

Long-term solutions for addressing the toxic algae bloom in Lake Erie involve reducing nutrient pollution at its source and implementing sustainable practices to prevent future blooms. This may include stricter regulations for agricultural and industrial practices, increasing funding for infrastructure improvements, and promoting sustainable land use practices. Monitoring and research efforts are also important for understanding and managing the issue in the long term.
