The Mühlsee, or Lake Mills, is a lake in Lans, Tyrol. It had an inflow and outflow, but they were buried in 2005. Nowadays, the lake is without fresh water.^{[citation needed]}

In 1840, the lake was drained. It was allowed to refill after a fire in 1902.^[1]

The lake is mainly used for fish breeding; bathing is prohibited due to the small size. Sometimes the lake is plagued by algae. There are high reeds along the shore often hiding fen puddles which act like quicksand.^{[citation needed]}
