Description

The construction of the dam began in 1972, and the accumulation in 1976. In 1977 it reached almost 25 million m³ of water. The second stage began in 1981, being designed for the accumulation of a water volume of 51.08 million m³. The dam was built on the Gladna river, a left tributary of the upper Bega river, about 4 km upstream from the village of Surducu Mic. The dike is built of ripraps with a concrete mask. The ripraps and the several thousand cubic meters of concrete support 417 m³ of water/m³ of ripraps. The dam has a height of 36 m, with an opening at the crown of 130 m, the length of the lake being 4 km, the width 3 km, and the maximum depth 17.2 m. It is the narrowest dam in Romania, relative to the volume of water held. Lake Surduc supplies drinking and industrial water to Timișoara and can set in motion the turbines of a 2 MW micro-hydropower system.
