Lake Aleksandrovac lies between the towns of Aleksandrovac and Kupinice in the Vranje Municipality, 8 km southeast of the City of Vranje. It was formed in 1963, following the erection of an 8m-high earthfill dam at the Ratajska Slatina site (Figure 1).

The dam was built based on a design document package, „Ratajska Slatina Micro-Reservoir in the Vranje Municipality“, prepared by JCI in 1960.

The dam project called for the reservoir to be used for farmland irrigation downstream from the dam and reservoir, along the right bank of the Južna Morava River. The farmland belonged to the Poljoproduct Agricultural Company.

Over time, the lake was increasingly used for recreation and fishing, while its irrigation function diminished with declining agricultural activity.

Since the catchment area of the proposed reservoir was small, project documents called for water to be delivered from the Donja Otulja River and discharged via a canal into the Južna Morava River.

In the late 1980’s, the water delivery conduit ceased to function and resulted in the deterioration of lake water quality and uncontrolled growth of macrophytes which ultimately enveloped the entire lake.

Preliminary and detailed designs for the rehabilitation of Lake Aleksandrovac addressed:

  • The installation of a water intake on the Donja Otulja River;
  • New pipelines and canals for water transport to Lake Aleksandrovac (2027 m long);
  • Rehabilitation of the lake (sediment dredging, development of beaches and walkways, bioengineering measures along the lakeshore, and the like), and rehabilitation of dam overflow and outlet components;
  • Construction of a discharge canal from Lake Aleksandrovac to the Južna Morava River (2267 m long).
