The rate of dissimilatory sulfate reduction during summer stratification in Lake Mendota was estimated from sulfate and sulfide profiles. The electron flow via sulfate reduction in the anaerobic hypolimnion was about 25% of the electron flow via methanogenesis. There is a possible stoichiometric relationship between anaerobic electron flow and anaerobic carbon mineralization.
