What environmental issue is associated with Lake Allegan?

• A. Heavy metal contamination
• B. Oil spills
• C. Algal blooms
• D. Recreational overuse

Answer: (C)

The environmental issue most commonly associated with Lake Allegan is algal blooms. Algal blooms occur when there is an excessive growth of algae, often fueled by nutrient pollution from fertilizer runoff, wastewater discharges, or other sources containing high levels of phosphorus and nitrogen. These blooms can lead to harmful effects on water quality, including decreased oxygen levels, which can harm aquatic life, and can produce toxins that may pose health risks to humans and animals. Managing nutrient input into the lake is crucial to mitigate these blooms and maintain the ecological balance of the water body.
