Have you ever wondered what lies beneath the surface of a seemingly ordinary lake? Right here in Stockholm, nestled amidst the greenery of Bromma, lies Kyrksjön. It may look like any other body of water, but it holds within its depths a rich history and a remarkable ecosystem that deserves our attention.
This small lake was once a much larger expanse, stretching into the neighboring Spånga parish. Legend tells us its outflow was a mighty waterfall cascading over nine meters of white water. The lake was lowered to its current level in 1863, leaving a lingering reminder of its former grandeur. This lowering also led to a near extinction of the fish population, with only crucian carp managing to adapt to the limited oxygen levels.
But Kyrksjön is not just a relic. It is a vibrant sanctuary for avian life, particularly the black-necked grebe. This bird, which is classified as “vulnerable” in Sweden, finds a haven amidst Kyrksjön’s dense vegetation. The surrounding forest is further home to other feathered friends, including nightingales and marsh warblers, offering a chorus of sweet melodies that often blend with the gentle lapping of the water.
Kyrksjön also serves as a breeding ground for various amphibians, including common frogs, moor frogs and common toads. While the future of the great crested newt remains uncertain, they too are a part of this delicate ecosystem.
So, as you gaze upon the tranquil waters of Kyrksjön, remember that beneath its seemingly placid surface lies a hidden world of stories and creatures. In this small lake, we find a captivating narrative of transformation, resilience and the delicate balance of nature.
