From: Global carbon budget of reservoirs is overturned by the quantification of drawdown areas
a, Theewaterskloof Dam, South Africa, during the water crisis of 2018. The black/white line shows the reservoir margin at maximum capacity31. Drawdown area = 73% of maximum reservoir area. b, Dry part of Hassel pre-dam, Germany, 2014. c, Global distribution of 6,749 reservoir drawdown areas. Colours indicate average drawdown area during the period 1985–2015 as percentage of maximum reservoir area. Landsat-8 image in a courtesy of USGS; photograph in b courtesy of Kurt Friese.
