Hydroclimatic Atlas of Southern Québec

The Hydroclimatic Atlas describes southern Québec’s current and future water regime in order to support the implementation of water management practices that are resilient to climate change. Note that results pertaining to the 2030 and 2080 horizons are described in the fact sheets for each river segment.
