The lake supplies a significant portion of Berlin's drinking water, processed by the nearby Friedrichshagen waterworks.
The Müggelberge range contains the Teufelssee, a separate, smaller lake often confused with the main reservoir.
The lake’s water quality is officially monitored by the Berlin State Office for Health and Social Affairs during the summer season.
The sediment at the bottom of the lake provides a geological record of the region's climate history over the last 10,000 years.
Müggelsee is the largest lake in Berlin, covering approximately 7.4 square kilometers with a maximum depth of 8 meters. It serves as a vital recreational hub and a primary drinking water reservoir for the city. The lake is fed by the Spree River, which flows into the western end and out through the southeastern basin. Geologically, the lake originated from subglacial channels carved during the Weichsel glaciation. The surrounding landscape includes the heavily forested Müggelberge hills, which reach elevations of up to 115 meters. Visitors utilize the area for swimming, sailing, and rowing activities throughout the warmer months. Several public beaches, including the notable Strandbad Müggelsee, provide structured access for swimming. The lake is protected under various environmental regulations to maintain water quality and preserve the surrounding ecosystem.
The viewing platform at the Müggelturn tower offers an elevated panoramic perspective of the entire lake basin.
