We present 50 years of monitoring data on water quality of Lake Stechlin, a deep, dimictic hardwater lake in northeastern Germany known for its exceptionally clear water. Although located in a forested catchment, the lake has undergone major changes in recent decades, including a period of massive heating of surface water when receiving cooling water from a nearby nuclear power plant (1966-1990), accompanied by a greatly shortened water residence time from more than 40 years to less than 300 days. These changes are superimposed by a long-term trend of surface water warming and a concomitant decrease in winter ice cover. Total phosphorus concentrations have quadrupled since 2010 and zones of deep-water oxygen depletion have greatly expanded. The presented dataset covers basic water-chemical and physical records taken at monthly to fortnightly intervals from 1970 to 2020, documenting limnological changes during that period. Furthermore, it serves as a valuable basis to assess and project potential consequences of climate change and other types of environmental change on deep clearwater lakes in temperate climates.
我们展示了施特克林湖50年的水质监测数据，该湖是德国东北部一个深的、双季混合的硬水湖，以其格外清澈的湖水而闻名。尽管该湖位于森林覆盖的集水区，但近几十年来它经历了重大变化，包括在从附近核电站接收冷却水期间（1966 - 1990年）地表水出现一段大规模升温时期，同时水停留时间从40多年大幅缩短至不到300天。这些变化叠加了地表水升温的长期趋势以及冬季冰盖随之减少的情况。自2010年以来，总磷浓度增加了两倍，深水缺氧区域大幅扩大。所呈现的数据集涵盖了1970年至2020年期间每月至每两周采集的基本水化学和物理记录，记录了该时期的湖沼学变化。此外，它为评估和预测气候变化及其他类型环境变化对温带气候下深的清水湖的潜在影响提供了宝贵依据。
