Lillsjön

Could a lake so small hold such a rich tapestry of life? Here at Lillsjön, the answer is a resounding yes. Lillsjön, meaning “The Small Lake,” may be small, tucked away in Bromma, a suburb of Stockholm, but don’t let its size fool you. This unassuming body of water teems with stories and secrets. Lillsjön is one of four lakes gracing Stockholm’s western suburbs, alongside Kyrksjön, Judarn, and Råcksta Träsk. It’s nestled within the charming Lillsjöparken, a green oasis bordered by the bustling pulse of major roadways. Lillsjön offers a tranquil escape, a place to connect with nature amidst the urban hum. The lake is shallow, averaging a depth of about two meters, with a maximum depth of three. Its surface area spans 10.7 hectares, holding a volume of approximately 196,000 cubic meters of water. Lillsjön connects to the larger Ulvsundasjön through a channel. Interestingly, the water flow sometimes reverses, with Ulvsundasjön replenishing Lillsjön. This delicate balance contributes to the lake’s unique ecosystem. Lillsjön is a haven for a surprising variety of fish. Ten species, including perch, northern pike, carp bream, and pikeperch, call these waters home. Even the elusive signal crayfish occasionally makes an appearance. Above the surface, Lillsjön is a vital breeding ground for birds. Mallards are a common sight, alongside Eurasian coots and great crested grebes. The reeds provide shelter for reed warblers and reed buntings, while other migratory birds use Lillsjön as a resting point on their long journeys. The surrounding park, Lillsjöparken, adds another layer of charm to this urban oasis. Deciduous trees and lush lawns provide a tranquil backdrop for leisurely strolls. The presence of three allotment gardens nearby speaks to the community’s connection with the land. Despite its idyllic setting, Lillsjön faces environmental challenges. Nutrients and metals, originating from surrounding roads and settlements, impact the water quality. Efforts to improve the lake’s health are ongoing, aiming to preserve its role as a vibrant ecosystem and a cherished recreational spot. A visit to Lillsjön offers more than just a glimpse of nature. The surrounding area is rich with history. Petroglyphs, ancient runestones, and the stately 17th-century Ulvsunda Palace are within easy reach. These historical echoes add a unique dimension to the experience, connecting the present moment to the whispers of the past.
