Waldschwaigsee

Could a highway give birth to a lake? At Waldschwaigsee, the answer is a resounding yes. This picturesque lake, nestled west of Karlsfeld in the Dachau district, owes its existence to the construction of the B471 federal highway. Before 1945, a solitary farmstead, the Waldschwaige, occupied this space. Around 1971, the need for gravel for the highway’s construction led to the creation of a gravel pit. This pit, initially a scar on the landscape, soon transformed into something beautiful. Groundwater and rainfall filled the void, giving rise to the Waldschwaigsee. The lake spans nearly 10 hectares and plunges to depths of up to 14.6 meters. During the gravel extraction, unwanted materials like roots, clay, and humus were piled up. This heap, over time, solidified and became the lake’s island. This island, a little over 3,500 square meters, has been under landscape protection since 1975. It’s a haven for wildlife, especially wild geese and other waterfowl, adding to Waldschwaigsee’s romantic charm. The lake’s water quality is generally excellent, monitored regularly by the Dachau Health Department. The Waldschwaigsee isn’t solely a natural wonder. It serves as a recreational hub and supports local fish farming. The Karlsfeld Fishing Association has its hut on the northern shore, where they crown their annual “Fishing King”. A seasonally operated rescue station, built by the German Life Saving Society (DLRG) in 1988, ensures the safety of swimmers during the summer months. From May 15th to September 15th, animals are not permitted at the lake. This measure helps protect the delicate ecosystem of the island bird sanctuary. The lake’s primary water source is groundwater and rainfall. However, the nearby Krebsbach stream, connected by ditches, offers a way to artificially regulate the water level. This feature is essential for managing both heavy rainfall and periods of drought. This keeps the water surface fluctuating between 10 and 11 hectares. Waldschwaigsee stands as a testament to the unexpected beauty that can arise from human intervention. It’s a place where nature reclaimed its space, creating a haven for both wildlife and those seeking respite in the heart of Bavaria.
