The lake looks so wonderfully turquoise and clear that you want to jump straight into it. Nicola Lindemann-Berk can only warn against this. In the water, which is up to 40 meters deep, there are very cold underwater currents, which pose a risk of accidents, says the qualified engineer. However, the 23 hectare lake has its drinking water quality, although it is an active open pit. In 1969, 50 years ago, the quarrying of high-purity white quartz gravel and quartz sand began on Schmalen Allee in Witterschlick. At that time, Quartzwerke Witterschlick was founded with a 50 percent holding by Servais-Werke. In 1973 and 1976, the Servais works acquired the remaining shares.
