Glan, Freshwater lake in Östergötland, Sweden

Lake Glan is a freshwater lake in Östergötland, Sweden, lying across the municipalities of Finspång and Norrköping. Its shoreline is long and irregular, with many bays and inlets that break up the water's edge into distinct sections.

The area around the lake has been settled since early prehistory, with communities relying on the water and fish to survive. Over time, small settlements grew along the shores and shaped the landscape that visitors see today.

The lake draws people from Finspång and Norrköping who come to fish, swim, and walk along the shore during summer weekends. The shallow bays near the shore are the most used spots, where families tend to gather on warm days.

There are several access points around the lake, some with basic facilities for fishing and swimming. Summer is the easiest time to visit, when most of the shore is accessible and conditions are comfortable.

Glan lies only 21 metres above sea level, not high in the landscape. In summer the water at the bottom stays around 14°C, unusually warm for a lake this size. The lake is also known for blowing up very quickly, and it is Norrköping's main drinking-water source.
