Mechower See is a lake in the Nordwestmecklenburg district in Mecklenburg-Vorpommern, Germany.

Only a fisherman from Klocksdorf was allowed to fish the lake twice a year, and a border troop boat monitored it.

Nevertheless, several people managed to overcome the barriers, swim across the lake and escape to West Germany.

Although the lake is now surrounded by dense tree cover, it was completely free of trees at the time of the division of Germany.

After the fall of the Wall, the border between Wietingsbek and Schlagbrügge was ceremoniously opened on Lake Mechow on December 31, 1989.
