The main sources for the dam lane impounding are the Struma River andtributaries thereof: Matnitsa and Kladnitsa Rivers. Additional water is delivered to the dam lake from theVladaiska andPalakariiska Rivers through the Vladaiski and Palakariiski channels. The dam body is aconcrete, hollow gravity, Nocli type one, built up of 25 concrete blocks (buttresses). Maximum dam height is 55.00m. The energy isdissipated by means of existing stilling basin and lateral-flow spillway. The stilling basin is 6.00 m wide and 43.00 mlong. The bottom outlet is built in expanded block 15th of thedam body. The bottom outlet comprises two pipes DN1000 with conveyance capacity of 30 m3/s each at water level on 840.0 m in thedam lake. The water intake tower is built up out of the dam bodyand isfounded in the foundation pit right-hand slope on elevation 811.80. The tower is a single-chamber one with wet chamber. The pressure tunnelstarts from the water intake tower at elevation 811.00 m (811.80 m).  The tunnel profile is bored with great overcuts filled up according to archive data with concrete. The grouting curtainis a single-row one with boreholes drilled at intervals of 1.50 m to depths 16÷22 meters.
