Short summary
Based on an intense monitoring of CO2 concentrations and organic and inorganic carbon in the reservoir, in the rivers upstream and downstream, and of CO2 emissions from the drawdown area, we confirmed the importance of the flooded stock of organic matter as a source of C fueling emissions and we show that the drawdown area contributes, depending on the year, from 50 to 75 % of total annual gross emissions in the flat and shallow Nam Theun 2 Reservoir.
