Yearly Temperature Fluctuations

Caption

The Sesan, Srepok and Sekong rivers had sensors that monitored river temperature year-round between 2004 and 2011. Before 2009 (labeled in blue), all three rivers had a similar temperature pattern: The water started to warm up at the beginning of the dry season, around November or October, and then cooled off once the wet season started in April or May. But after 2009 (labeled in red) the Sesan and the Srepok rivers, which had major dams built during that time, stayed cool year-round.
