Résumé

Cyclic presence of different types of phytoplankton, including cyanobacteria, in the lakes at various depths and eventually at some wells was observed at a 2-lake bank filtration site. Due to their potentially high toxicity, understanding the origin and pathways of cyanobacteria is crucial to maintain the security of the drinking water supply. Measurements of temperature were carried out at Lake B from February 2017 to May 2018 in order to better understand the lake’s dynamics. We determined that complete mixing of the water column occurred from mid-October to mid-November. By anticipating the extent and the timing for the autumnal turnover, one can adjust management strategies. This work is the first step towards a better understanding of the controlling factors over cyanobacteria breakthrough.
