Wetlands

Wetlands are lands that are seasonally or permanently flooded by shallow water. They also include lands where the water table is close to the surface.

The wetland polygons are managed independently from other hydro data classes and may overlap water bodies or other hydro data.

Not all wetlands have been identified and mapped. Active maintenance is ongoing province wide. The currency and accuracy of the spatial representation is variable and requires on-the-ground verification.
