West of Cologne the RWE trust is creating the biggest open brown coal pit in Europe. The mine will be open until 2050 and will reach a depth of 400 meters below the existing surface level. The remaining hole will be filled with groundwater until 2100, thus becoming the second largest inland lake in Germany.
