The Okhta is a river in Vsevolozhsky District of Leningrad Oblast and the eastern part of the city of Saint Petersburg, Russia. It is the largest right tributary of the river Neva. It joins the Neva 12km (07miles) upstream of the Neva's mouth, within the city limits of Saint Petersburg. The length of the Okhta is 90km (60miles), and the area of its drainage basin is 768km2.[1] Its largest tributary is the Okkervil (left). The Rzhevsky Reservoir (5km (03miles) long, 120m (390feet) wide, with a volume of 4 mln m³) has been built on the Okhta. The Utkina Dacha estate is located on the banks of the Okhta close to the mouth of the Okkervil.
