The Malter dam was built between 1908 and 1913. It is located north of the town of Dippoldiswalde in the Eastern Ore Mountains. The dam is a gravity dam made of quarrystone masonry with a solid cross-section. The historic structure is primarily used for flood protection, local recreation and hydropower generation.

In order to restore flood safety, it is necessary to lower the collecting channel bed and build a second channel. The centrepiece of the new construction is the air-side dividing structure, which pressurises the existing channel and uses the new channel in the event of higher discharges.
