🌊 Gammelstadsviken, Norbotten

Gammelstadsviken is a lake located in Luleå Municipality, in the province of Norrbotten, and is part of the Altersundet–Luleälven coastal area. The lake is a shallow clay plain lake, has an area of 2.19 square kilometres and has an elevation of 2 metres above sea level. It also has a low water turnover due to small catchment area and low precipitation in the coastal area, and its water depth does not exceed 4 m. This means that it is slowly becoming overgrown, today not due to land uplift, but due to subsidence by mud deposits and aquatic vegetation. Gammelstadsviken is located 5 km northwest of Luleå in the Gammelstadsviken Natura 2000 area. The lake was previously a sea bay but is now drained by the watercourse Sellingsundet. Gammelstadsviken has a rich bird fauna, of both migrating, resting and breeding birds: about 200 bird species have been observed at the lake.
