- Grasslands and wetland birding near the city.
- Quiet cycling and photography routes around the lake.
The story
A former Bengaluru water reservoir whose shifting lakebed, grassland and scrub now form a conservation landscape valued for birds—and damaged when visitors mistake open ground for a driving arena.
The story of Hesaraghatta Lake
Hesaraghatta is best understood as a landscape rather than a permanently full lake. The reservoir belonged to Bengaluru’s historic water-supply system, while rainfall and catchment change now produce radically different wet and dry appearances.
The two exact lake photographs on this page deliberately show that contrast: open water after heavy rain in September 2017 and cattle grazing across a dry lakebed. Neither state is a promise about what a visitor will see this week.
Bird Count India treats the lake, grassland, scrub, Mathkur and nearby institutional land as distinct birding hotspots. That division is useful: a single map pin cannot represent where waterbirds, grassland raptors and scrub species will be found on a particular morning.
Conservation work has pushed the wider Hesaraghatta grassland towards formal protection. The visitor consequence is straightforward: established public approaches and habitat rules matter more than the shortest line to a map centre.
A dry surface is still habitat and working grazing land. Driving across it, pursuing birds or crowding a nest destroys the very quality people travel to see.

History
The lake was created as part of Bengaluru’s historic water-supply infrastructure in the late nineteenth century.
Declining and variable inflow transformed the public image of Hesaraghatta from dependable reservoir to alternating water, mudflat and grassland.
Bird surveys and conservation campaigns now treat the wider landscape as one of Bengaluru’s important remaining natural areas.
Why visit
For dawn birding across several connected habitat types.
To read water-supply history through a reservoir that no longer behaves like a permanent urban lake.
To experience open grassland near Bengaluru while practising low-impact access.
