Could re-flooding the Sumas Prairie help buttress Abbotsford against climate change?

The B.C. government drained Sumas Lake in the 1920s to make room for farmland, displacing the Sumas First Nation and its members.
You’ve heard about fighting fire with fire, but what about fighting water with water?
It’s an idea at the heart of a proposal in a new UBC study, which suggests the best way to prevent flooding in a key part of the Fraser Valley might be to flood it intentionally.
The research, published in the journal Frontiers of Conservation Science, looks at the idea of restoring Sumas Lake in Abbotsford.
The B.C. government drained the lake in the 1920s to make room for farmland, displacing the Sumas First Nation and its members.
The Sumas Prairie was one of the parts of the Fraser Valley hardest hit by the 2021 floods that devastated southwestern B.C.
“Given that the risk of climate change-induced flooding is increasing, that area will flood again,” study senior author Tara Martin, a professor of conservation sciences, told Global News.
“In a time of climate crisis, we can’t continue to do the same old thing. We can’t continue to try and keep the water away, keep the fires away. We have to adapt.”
Martin’s study proposes what is known as “managed retreat,” the purposeful relocation of people and infrastructure to safer areas.
