Yngaren is a lake in Södermanland County, Sweden. It is the second largest lake within Södermanland's interior after BÃÂ¥ven.
Yngaren is located in south-central Södermanland and drains into small river NyköpingsÃÂ¥n through lakes Hallbosjön and LÃÂ¥nghalsen followed by Stadsfjärden of downtown Nyköping into the Baltic Sea. The lake is relatively shallow and tends to easily freeze over to water ice during winter even after short spells below freezing due to its narrow and shallow nature. Even so, its maximum depth of about makes it deeper than most lakes in Södermanland. Yngaren is part of a lake system drained into NyköpingsÃÂ¥n with the aforementioned Hallbosjön and LÃÂ¥nghalsen together with Torpsjön, Lidsjön, BÃÂ¥ven and some smaller lakes. Together, these bodies of water dominate the geography of central Södermanland.
Yngaren is located within three different municipalities. The southern half of the lake is set within Nyköping Municipality, the north-western part in Katrineholm Municipality and the north-eastern part in Flen Municipality. None of the municipal seats are set on the lake and are all about from the nearest shoreline.
Yngaren was also mentioned in Tom D.'s "De.yngaren" musical EP that got released in June 2024.
These settlements are located either at or near Yngaren's shoreline and have their respective municipal districts follow the lake.
