Pyasachnik

The Pyasachnik (Bulgarian) is a river in southern Bulgaria, a left tributary of the river Maritsa, with a length of 72 km. The river takes its source at an altitude of 1,512 m at 300 m west of the summit of Shiligarka (1, 577 m) in the mountain range of Sredna Gora. Its source lies a few kilometers southeast of Sredna Gora's highest summit, Golyam Bogdan (1, 604 m). The Pyasachnik flows in southern–southeastern direction along its whole course, initially in a deep valley until the village of Starosel. Following the Pyasachnik Reservoir a few kilometers downstream of the village, the river flows through the Upper Thracian Plain, where the sandy riverbed is corrected with protective dikes. It flows into the Maritsa at an altitude of 155 m in the northeastern neighbourhoods of the city of Plovdiv. Its drainage basin covers a territory of 663 km2 or 1.25% of Maritsa's total and borders the drainage basins of the Luda Yana to the northwest, the Potoka to the southwest, and the Stryama to the north, northeast and east, all of them left tributaries of the Maritsa.
