2024 Surface Runoff Modeling - version 2 (2025-09-19)

Runoff data produced by the Montreal Metropolitan Community. These data allow the identification of areas in topographic depression likely to be affected by the accumulation of water (also called “basins”) as well as the flow paths between them. This mapping is based on high-precision surveys, from the 2024 metropolitan lidar.
