Wildfire Affected Lake Water Carbon Data [Québec, Canada and Minnesota, USA, 2021-2022]

Sampling campaigns took place once in June or early July after the onset of thermal stratification (although not all lakes were deep enough to stratify) over two years; Côte-Nord was sampled in 2021, while Minnesota and Saguenay were sampled in 2022. Sampling varied in the time since the fire occurred, with the Côte-Nord fire (CN, 128 km2) occurring 3 years pre-sampling, the Saguenay fire (SAG, 599 km2) occurring 2 years pre-sampling, and the Greenwood Fire in Minnesota (MN, 108 km2) occurring 8 months pre-sampling.
