Mordhana Dam is part of the larger Palar River water‑management system, capturing runoff from the Koundanyanadhi sub‑basin. Its uncontrolled spillway design means water flows over the crest whenever the reservoir exceeds the FRL, creating a spectacular, thunderous cascade during monsoon peaks—an unforgettable sight for visitors.
History & Significance
Constructed in the early 2000s (exact year not publicly documented), the dam was built primarily for irrigation and groundwater recharge in the surrounding agrarian districts. By regulating the flow of the Palar tributary, Mordhana Dam helps sustain over 800 acres of farmland, supporting local livelihoods and contributing to Tamil Nadu’s food security.
Beyond its utilitarian role, the reservoir has become a modest but growing tourist attraction. The calm water surface at sunrise and sunset mirrors the sky, making it a favored spot for landscape photography and bird‑watching. The dam’s location—away from major highways yet accessible by road—offers a tranquil retreat for city‑dwelling travelers seeking nature’s quiet.
3. How to Get There
By Air
The nearest major airport is Kempegowda International Airport (BLR) in Bengaluru, about 190 km (≈ 4 hrs) away. From there, you can rent a car or take a private taxi to Peranampattu.

The closest railway station is Hosur Junction (HSRA), approximately 70 km from the dam. Hosur is well‑connected to Chennai, Bengaluru, and other South Indian metros. From Hosur, hire a local cab or board a state bus heading toward Peranampattu.

4. Best Time to Visit
| Season | Weather | Visitor Experience |

| Winter (Nov – Feb) | Cool, dry, temperatures 18‑28 °C | Ideal for sunrise/sunset photography, comfortable trekking around the reservoir. |
| Pre‑Monsoon (Mar – May) | Warm, occasional showers | Good for bird‑watching; the water level is moderate, exposing more shoreline for walks. |
| Monsoon (Jun – Sep) | Heavy rains, high water flow | Dramatic spillway action; the reservoir swells, creating misty vistas—but road conditions may be slippery. |
| Post‑Monsoon (Oct) | Pleasant, receding water levels | Perfect for picnics and boating (if local operators are available). |
Tip: The most photogenic moments occur early morning (5:30–7:00 am) when the sun paints the water in gold and the mist from the spillway lingers.
