Oct. 18, 2014 – Oct. 10, 2017
South Africa’s Western Cape province has been suffering a drought since 2015, when it received about 60 percent of its normal rainfall. Rain amounts continued to plummet in the two subsequent years. These images show Theewaterskloof, the province’s largest reservoir, at full capacity in October 2014 and at 27 percent of capacity in October 2017. Exposed sediment around the edge of the basin in the later image shows where the water level has declined.
