Poondi reservoir

Poondi Lake or Sathyamoorthy reservoir is the reservoir across Kotralai River in Tiruvallur district of Tamil Nadu State. It acts as the important water source for Chennai city which is 60 km away. Poondi Reservoir (later named as Sathyamoorthy Sagar) was constructed in 1944 across the Kosathalaiyar River or Kotralai River in Thiruvallur district with a capacity of 2573 Mcft and placed in service for intercepting and storing Kosathalaiyar River water. Surplus water flows down the river which is again intercepted by Tamaraipakkam Anicut and diverted to Sholavaram Lake and Puzhal lake.
