The topography of Sukhna Lake and its immediate surroundings transitions from the flat plains of Chandigarh to the undulating, hilly terrain of the Shivalik range.
* **Lake Basin:** The lake sits in a shallow, artificially created basin. Its depth fluctuates significantly depending on monsoon rains. * **Embankment/Promenade:** The southern edge of the lake features a 2-kilometer-long solid earth embankment, topped with a paved promenade for pedestrians. * **Surrounding Terrain:** To the north and east, the terrain rises into the forested, rolling hills of the Shivalik catchment area. To the west lies the world-famous Rock Garden and dense city greenery, while the south is bordered by the manicured landscapes of the Chandigarh Golf Club.
