Delsjön
Lakes in Gothenburg, Sweden
From Wikipedia, the free encyclopedia
Delsjön consists of two interconnected lakes—Stora Delsjön (Great Delsjön) and Lilla Delsjön (Little Delsjön) both of which are located in eastern Gothenburg, Sweden, within the Delsjöområdet nature reserve.[1] The lakes form a primary freshwater reservoir for the city of Gothenburg, storing raw water pumped from the Göta River.[2]

Geography and hydrology
The combined lake system covers a surface area of approximately 1.8 km2 (0.69 sq mi) at a baseline surface elevation of 69.5 m (228 ft) above sea level.[3] Stora Delsjön forms the larger western body, reaching a maximum depth of 22.5 m (74 ft), while Lilla Delsjön lies directly to the east.[3]
The lakes form part of the Delsjöområdet nature reserve, a forested area set aside for environmental conservation and public recreation.[1] Water levels are regulated according to municipal drinking water needs; in the event of quality disruptions or elevated salinity in the Göta River, the river intake at Lärjeholm is temporarily closed and raw water is drawn directly from Delsjön to the Lackarebäck water treatment plant.[2][3]
History
Human settlement and usage around Delsjön date back several centuries. During the 18th and 19th centuries, the surrounding forest and shorelines served as outlying pasture lands and croft settlements for regional agricultural estates, including Stora Torp.[1] As Gothenburg expanded during the late 19th and early 20th centuries, municipal authorities developed the Delsjön basin into a formal urban water supply reservoir to meet the growing population's demand.[3]
Recreation
Delsjön is one of Gothenburg's primary outdoor recreation areas.[1] A public beach equipped with jetties, piers, and amenities is situated on the northwestern shore of Stora Delsjön.[1] Additional recreational facilities around the lakes include maintained hiking and running trails, kayak and canoe rentals, sports fishing, and historic cafes along the shore of Lilla Delsjön.[1]
