A majority of Hg methylation is a result of microbial activity and the abundance of inorganic Hg within the water reservoirs （Eckley et al., 2017）. Compared to natural lakes and rivers, reservoirs have elevated Hg levels from the decompo- sition of recently flooded organic material which promote Hg release and enhance microbial methylation of Hg （Eckley et al., 2017）.
