The Ialpug (Romanian; Moldavian; Moldovan: Râul Ialpug, Ukrainian: Ялпуг) is a river that crosses Moldova and the Odesa Oblast of Ukraine. It rises in the vicinity of the village Tomai, Leova District), flows in the south direction in parallel with the Prut, Cimișlia District, Gagauzia, Taraclia District, then Bolhrad Raion in Ukraine and flow into Lake Yalpuh near the city of Bolhrad.
In his paper Descriptio Moldaviae ("Description of Moldavia"), written in Latin 1714–1716, the scholar voivode Dimitrie Cantemir thus describes this river: "Cahulul, Salcia and Ialpuhul, which are in Moldavia and Bessarabia, increase the Danube. Of the latter, only the Ialpuh flows without consistency, the others are more stable than flowing."[1]
