- •
Lake levels in the extreme drought are on average 1 m lower than long-term average.
- •
DIC species and chemical variables significantly increase in the drought period.
- •
Drought can switch the lake system from sink to source of atmospheric CO2.
- •
Varied empirical k models provide a reasonable range of CO2 emission rates.
- •
Our calculated CO2 emission rates are in the low end of previously published ranges.
