The glacial hydrology of the meltwaters of the ice sheet during deglaciation in a large river basin has been reconstructed on the basis of heights of thresholds and saddles of bedrock topography, glaciofluvial accumulation forms (eskers, deltas and plains of sorted material) and erosional landforms (drainage channels and shorelines) as well as a few terminal moraines. The water level of glacial lake dropped in several stages. The lake existed and deglaciation took place before 9740±280 years B.P. The deglaciation took place at a much faster rate in the studied region than later in western Lapland.
