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. (A lined canal known as Poondi Canal was later constructed in 1972 to convey water from Poondi Reservoir to Sholavaram Lake). This reservoir was constructed and opened by Chennai Corporation Mayor Sathyamurthy at the cost of Rupees 65 lakhs.
The original complex of Oondreswarar Temple is believed to have been built by Cholas, while the present masonry structure was built during the 16th century. The temple was moved to the current location in 1942 to ease the construction of the reservoir.
The construction of a lined channel from Poondi to Tamaraipakkam for a length of 15 km. to convey water from Poondi to Tamaraipakkam was completed in 1972 to reduce the transmission loss. The combined capacities of Sholavaram and Redhills lakes were increased by 700 Mcft by raising the lake bunds. Thus, the combined storage capacity of Poondi, Sholavaram and Redhills was increased to 6296 Mcft (Poondi: 2573 + Cholavaram: 881 + Redhills: 2842). The irrigation rights of Sholavaram lake and Redhills lake were acquired in 1962 and the entire storage was made available for the City supply.
An agreement was signed jointly by Governments of Maharashtra, Karnataka and Andhra Pradesh on April 14, 1976 to spare 15 thousand million cubic feet (TMC) of Krishna water to Chennai city. Following this, an accord between Andhra Pradesh Government and Tamil Nadu Government was signed for Telugu Ganga project on April 18, 1983 for drawing 15 TMC of Krishna water to Chennai City from Sri Sailam Reservoir to be conveyed through Somaseela and Kandaleru Reservoirs and ultimately a net quantity of 12 TMC (after loss of 3 TMC en route in evaporation and seepage) will reach the Tamil Nadu border.
