Short summary
Freshwater reservoirs emit greenhouse gases (GHGs) due to organic matter decay after landscape flooding. In order to better understand this phenomenon, we performed a comprehensive carbon footprint assessment of a tropical reservoir. Contrary to predictions, 89 % of measured emissions occurred downstream of the dam. Comparing predicted vs. measured emissions revealed weaknesses in our current modeling framework and insights to improve our ability to quantify and reduce reservoir GHG emissions.
