The lake is unique for being located at an altitude of approximately 1,500 meters above sea level.
It was developed by the British collector JD Begbie in 1864 to manage the local water supply.
The surrounding landscape is part of the Servarayan mountain range, a southern offshoot of the Eastern Ghats.
The lake serves as a natural catchment area, capturing runoff from the surrounding high-gradient slopes.
The specific shade of the lake water often appears green due to the high density of surrounding hill vegetation reflected on the surface.
Yercaud Lake, locally known as Emerald Lake, is a natural freshwater lake situated in the center of the Shevaroy Hills in Tamil Nadu. The lake is surrounded by hills and lush gardens, serving as the primary tourist hub of the Yercaud hill station. It features a boat house that offers pedal and rowing boat rentals for visitors to explore the central water area. A floating fountain is installed within the lake, often operating during peak tourist seasons. The perimeter includes a well-maintained walking path and manicured park areas for public use. The site serves as the central venue for the annual Yercaud Summer Festival, which includes flower shows and cultural events. It is a man-made lake created to collect rainwater runoff from the surrounding slopes. The depth of the water is relatively shallow, making it suitable for recreational boating. It remains the most accessible water body in the Salem district's high-altitude region.

Avoid boating during high winds or heavy rainfall, as visibility and control can become challenging.
Boating services may be suspended during heavy monsoons or if water levels become dangerously low; the lake area remains open year-round.
Avoid feeding the fish or birds in the lake; dispose of all plastic waste in designated bins to protect the ecosystem.
