Sig River

The Sig River, also known as Mekerra, is a river of Algeria.

The Sig River is a tributary of the Chelif River and flows through the town of Sig. For most of its flow the Sig is at 50 m elevation and ends about 30 km from the Mediterranean as the crow flies, and originates in the highlands south of the mountains of Daïa. The river is a wadi.

The area is characterized by a rough winter compared to other regions in Algeria, and a fairly warm summer. Rainfall does not exceed 400 mm per year.
