According to the Syria Central Bureau of Statistics (CBS), Mharda had a population of 17,578 in the 2004 census. It is the center of Mahardah District, one of the Hama Governorate's five districts, and the nahiyah ("subdistrict") of Mharda, which contained 21 localities with a combined population of 80,165 in 2004.

The Orontes River was recently dammed 3 kilometers north, and the Mahardah Dam on the Ghab plain is used to generate hydroelectric power. Mharda dates back to the same Hellenistic period of Apamea and the most notable archaeological remnant from this period is an old temple with stone doors and columns with Corinthian capitals transformed later into a church.

During the Syrian Civil War, Mharda has been targeted by rebels, yet remained under government control. According to pro-government media, the rate of attacks on Mharda increased during the course of the 2017 Hama offensive.
