Fig. 2From: Managing climate change in drinking water reservoirs: potentials and limitations of dynamic withdrawal strategiesAnnual mean temperatures (1), annual temperature trends for every month (2), and onset and end of summer stagnation for every year (3) for the three investigated reservoirs. The temperature trends are both for 3 m and 25 m below the surface. In (2) black stars denote significant trends, tested with the Mann–Kendall test. In (3) the whiskers indicate the maximum uncertainty for onset and end of stratification based on the observation datesBack to article page
