Lake Sukhodolskoye Lake Sukhodolskoye Lake Sukhodolskoye (; ) is a narrow 40 km long lake on the Karelian Isthmus located in Priozersky District of Leningrad Oblast, Russia. It is a part of the Vuoksi River basin, constituting its southern armlet, and drained by Burnaya River. Originally waters of Lake Suvanto (Lake Sukhodolskoye) quietly flowed into Vuoksi through a waterway at Kiviniemi. However, in 1818 the channel that had been dug to drain spring flood waters from Suvanto into Lake Ladoga unexpectedly turned into Taipaleenjoki (Burnaya River), which started draining Suvanto and decreased its level by 7 m. The Kiviniemi waterway dried out.
Baltic Ice Lake small channel in the Strait of Øresund. The lake was higher than sea level (which itself was lower than the present-day sea level) by some tens of metres. Lake Ladoga was part of it. Emergence of the land then closed the channel through the Strait of Öresund. The lake rose until at about 11,200 BP it broke through a narrow corridor in the region of Mount Billingen in present-day south-west Sweden; this used to be described by Quaternary geologists as a massive, single tap of Niagara-like force but it is now considered more likely that it happened in several steps
