How is the water supply to reservoirs protected?

The water supply to reservoirs is protected through various measures, including watershed management, which involves maintaining the health of the land surrounding the reservoir to prevent contamination. Regulations and zoning laws restrict industrial and agricultural activities near water sources. Additionally, water quality monitoring programs are implemented to detect pollutants early, and there are often buffer zones established to filter runoff before it reaches the reservoir. Regular maintenance and inspections of infrastructure also help ensure the integrity of the water supply.
