Lake Oron

Lake Oron (озеро Орон) is a lake in eastern Irkutsk Oblast (Bodaybinsky District), Russia.

Geography
It is located in the Kodar Mountains, to the south of the southern slopes of the Delyun-Uran Range. Lake Oron is connected to the Vitim River via a short waterway.

Hydrography
Lake Oron sits at an elevation of 353 m above sea level. It is 24 km long and 6.5 km wide, with a surface area of 51.3 km2 and a maximum depth of 184 m. The western and eastern slopes of the lake are practically vertical, and 85 percent of the lake is of a depth greater than 100 m, while the northern part of the lake that connects to the Vitim River is more shallow, with depths up to 18 m. The presence of deep faults beneath Lake Oron strongly suggest that the lake has a tectonic origin, with a hydrological regime determined more by changes in precipitation than by glacier meltwater.
