2018 Hydroclimatic Atlas

#Archive data from the 2018 Hydroclimatic Atlas

#Description

The Hydroclimatic Atlas describes the current and future water regime in southern Quebec in order to support the implementation of water management practices that are resilient to climate change.

#Avertissement

The 2018 version of the Atlas is now replaced by a more recent version on the website. Data from the 2018 version is archived on Data Québec for reference, for example for old reports or analyses referring to this version of the data. Any new study or analysis should use the most recent data available on [Data Quebec (Hydroclimatic Atlas 2022)] (https://www.donneesquebec.ca/recherche/dataset/atlas-hydroclimatique-2022) or on the Atlas website (www.cehq.gouv.qc.ca/atlas-hydroclimate-).
