Short summary

In this study, we showed that logging activities have a short-term impact (1 year after the perturbation) on water quality in boreal Eastern Canadian Shield lakes. However, this effect seems to mitigate 2 years after the perturbation. Further, the analysis of the absorbance and fluorescence data showed that while DOC concentrations did significantly increase in perturbed lakes, the DOM quality did not measurably change.
