- •
We measured fish Hg in 28 subalpine lakes.
- •
Fish Hg concentrations were negatively correlated with body condition.
- •
Fish Hg concentrations varied by up to 18x among lakes.
- •
Conifer density, lake size, sulfate, and dissolved organic carbon concentrations explained 87% of variation in fish Hg concentrations.
- •
Conifer density in a lake's catchment was the most important variable controlling fish Hg concentrations in subalpine lakes.
