Storsjön (Swedish pronunciation: [ˈstuːɧœn], lit. "The Great Lake") is a lake in Gävle Municipality and Sandviken Municipality in Gästrikland and is a part of Gavleån. Storsjön has an area of 70.6km², a greatest depth of 15, and is approximately 62 metres above sea level. The lake is drained by Gavleån. Experimental fishing has proved that there are many different varieties of fish here, such as perch, bream, sea bream and ruffe.[1]

An old saying says that the lake has "just as many islands as there are days in a year" which should not be interpreted literally, but simply means that they are too many to count (a more accurate figure would be around 150 islands). Storsjön is mostly around 2–5 metres in depth.

Old sources claim that Storsjön previously went by the name of Odensjön. This could possibly be proven by a 17th-century map where Gavleån, that flows through Gävle, is called Odensjöströmmen (lit. "Stream of Odensjön"). Storsjön is connected to Gavleån, which is connected to the sea.


By experimental fishing, these fishes have been caught:[2]

Catchment areas

Storsjön is a part of catchment area (671779-155196) which the Swedish Meteorological and Hydrological Institute calls Utloppet av Storsjön (lit. "The outlet of the Great Lake"). The median height is 67 metres above sea level and the area is 149km². If all the 367 catchment areas are counted upstream the accumulated area would be 2,168.02km². The catchment area Gavleån flows into the sea.[3] The catchment area mostly contains forest (36%). The catchment area has 70.48km² of water surface, giving it a lake percentage of 47.3%. Settlements in the area contain the size of 10.37km², or 7% of the catchment area.[4]
