Although the treatment of eutrophied lakes with aluminium (Al) compounds has been established for more than 40 years, publications reporting on long-term consequences for phytoplankton are rare. Here we present observations from Lake Barleber for the

Two morphologically similar pre-dams (Hassel and Rappbode pre-dams, Harz Mountains, Germany) of a large reservoir with different land use in their catchments were compared with respect to their physical, chemical, and biological properties in order t

Reservoirs can be viewed as sentinels of their catchments and a detailed monitoring of reservoir systems informs about biogeochemical and hydrological processes at the catchment scale. We developed a comprehensive online monitoring system at Rappbode

The application of lake marl for the in-situ restoration of eutrophic hard-water lakes with very low fresh water input has recently been carried out during a pilot study at Lake Arendsee, NE Germany. Calcite-rich lake marl taken from a natural deposi

Viele geschichtete Badegewasser im norddeutschen Raum sind von massiver Nahrstoffbelastung und sommerlichen Algenbliiten betroffen. Hohe Phosphorkonzentrationen bei einem niedrigen Angebot von minera/ischem Stickstoff fordern die Massenentwicklung st
