Germany's Coal Mines Transform into Huge New Lake Paradise

Eastern Germany's transformation of disused coal mines into a vast artificial lake complex, the Lusatian Lakeland, is reaching a new milestone. This ambitious project, begun in 1967, is creating Europe's largest artificial water landscape. The final addition, Lake Sedlitz, is set to open for swimming and boating at the end of April 2026.

The Lusatian Lakeland comprises 23 post-mining lakes covering 14,000 hectares. Future plans include connecting ten lakes by canals to create a navigable area of 7,000 hectares. The rehabilitation and flooding process, managed by the LMBV, is a generational undertaking, having cost approximately €7 billion to date, with an estimated €4.8 billion more needed over the next 25 years.

Water is actively channeled from rivers like the Neisse and Spree to fill the lakes, a process crucial for preventing acidic water from entering. This engineering feat results in a water surface area nearing 144 square kilometers, comparable to Italy's Lake Como. The lakes also serve as vital water reservoirs, aiding the region during drought periods.

As Lake Sedlitz opens, it will become the largest recreational lake in the Lusatian Lakeland. By June 2026, five major lakes will be interconnected, forming a significant contiguous water area. This development is boosting tourism, with a notable increase in visitors from the Czech Republic, and aims to establish the region as a premier destination for water sports and leisure.

This large-scale reclamation project is presented as a model for other European coal-mining regions facing structural change. As active mining operations are scheduled to cease by 2038, the remaining pits will also undergo flooding, further expanding this unique post-industrial water paradise.
