Klyazma in Russian

A river wholly within Russia, originating near Solnechnogorsk (Moscow Oblast) in the Moscow Uplands, whence it flows into and through Vladimir Oblast, approximately delineating its border with Ivanovo Oblast from near Repniki to near Mstyora, before returning to Vladimir’s interior, and thereafter approximately delineating its border with Nizhny Novgorod Oblast from near the point at which the river is bridged by the Volga Highway (E22) to its confluence with the Oka, whereof it forms a left tributary.
