Sholavaram Lake, reservoir in Thiruvallur district, Tamil Nadu, India

Sholavaram Lake is a large reservoir in Thiruvallur district, located about 24 kilometers north of Chennai. The water body stretches wide across open grounds, with a canal connecting it to Puzhal Lake to manage water flow between the two bodies.

The lake reservoir was built before 1877 during British rule and has long served as a water storage source for Chennai. A nearby airstrip used during World War II later became a racing track that hosted events from the 1960s through the 1980s.

Locals call it Sholavaram aeri, using the Tamil word aeri for a rain-fed reservoir. The lake and its canal to Puzhal lake are part of Chennai's drinking water supply, and the canal road is used by people from surrounding villages to reach the Thiruvallur main road, Redhills junction and the Chennai–Kolkata national highway.

The canal road between Sholavaram and Puzhal lake is used by locals to reach the Thiruvallur main road, Redhills junction and the G.N.T. road (NH5). The reservoir is rain-fed, so water levels and the condition of the earthen bunds vary with the monsoon; the bunds were repaired and the surplus area extended by about 200 mcft before 2015. Desilting began in April 2019.

The airstrip beside the lake was T-shaped: a 150-foot runway split by an 80-foot no-man's land, leaving two 35-foot tracks, with ambulances and marshals stationed in the central divide. Because the land belonged to the army, the Madras Motor Sports Club could not object when tanks were brought onto the runway for testing, which pushed the club to build a new track at Sriperumbudur.
