Which of the following is a method of managing algae growth in reservoirs?

Increased aeration
Regular flushing
Low rates of copper sulfate application
Increased sunlight

The correct answer is: Low rates of copper sulfate application

Managing algae growth in reservoirs is critical for maintaining water quality. The method involving low rates of copper sulfate application is effective because copper sulfate is an algaecide that targets and helps reduce the population of algae without drastically disrupting the aquatic environment. Properly controlled application can hinder growth by interfering with photosynthesis and cellular metabolism in algae, leading to its eventual decline. Increased aeration may enhance oxygen levels and promote the growth of beneficial organisms, while regular flushing is often more focused on pollutant removal than specifically targeting algae. Additionally, increased sunlight can actually encourage algae proliferation, as many algae thrive in illuminated conditions. Therefore, careful and judicious application of copper sulfate serves as a targeted strategy for controlling algae growth effectively in reservoirs.
