Advisory lakes were characterized as having higher sediment Hg and organic matter and lower total sulfur content compared to non-advisory lakes, and results highlight the importance of sulfide and organic carbon availability associated with potential Hg methylation biogeochemical processes. Advisory lakes generally had higher percentage of areal development and grasslands, higher catchment to lake area, and lower percentage of wetlands compared to non-advisory lakes. These results signify the importance of minimizing watershed sediment transport and associated organic carbon loading as effective Hg fish tissue lake management strategies.
