The region's capital was Yamoussoukro and its area was 8,875 km2.

[2] At the time of its dissolution, Lacs Region was divided into five departments: Attiégouakro, Didiévi, Tiébissou, Toumodi, and Yamoussoukro.

Attiégouakro Department was created in 2009 and was therefore part of Lacs Region for only a short time.

Lacs Region was abolished as part of the 2011 administrative reorganisation of the subdivisions of Ivory Coast.

The territories of the departments of Didiévi, Tiébissou, and Toumodi became the second-level Bélier Region in the new Lacs District.
