Sumas First Nation built on higher ground, unaffected by flooding in former lake bed, says chief

The chief of the Sumas First Nation near Abbotsford, B.C., says the community is built above a badly flooded section of the Fraser Valley, which would keep them safe from rising waters if a drained lake reappeared, according to an elder.

The Sumas Lake, which used to extend from South Chilliwack to Sumas, Wash., was pumped dry a century ago to make room for agriculture. Now, it has been filled by catastrophic flooding that has displaced thousands.

Sumas First Nation Chief Dalton Silver said despite the devastation caused by flooding over the past week, the Sumas First Nation is "coping quite well" as their houses are built on ground that's higher than the ancient shallow lake.

"We had elders that told us before that should this lake ... come back our homes would be OK. We knew the levels of the lake before."

The lake also used to be their primary food source, according to Silver, and their ancestors told government officials in the early 20th century that draining the river would cause starvation for the Sumas people.

"It is something that our people never would have even thought of doing, altering nature in such a way."

Ultimately, the lake was drained between 1920 and 1924.

WATCH / Massive pumps needed to keep area dry

The four pumps at the Barrowtown Pump Station are responsible for keeping water from the Fraser River at bay, but they are currently not keeping up with water that is also flooding in from the Nooksak River south of the Canada-U.S. border.

"Our hearts go out to all our neighbours around us," said Silver.

River people

Silver said the Sumas First Nation had several villages along the lake, with up to 10,000 people living in that part of the valley before European contact.

The Sumas are a part of the larger Sto:lo Nation.

"Sto:lo basically means river, we are the river people," said Silver.

Silver said historically, about 85 per cent of the Sumas diet came from the lake, including salmon and freshwater mussels. They also used canoes to reach islands on the lake for deer hunting.

"There were a lot of stories about the loss of the lake and actually the devastation for us then," said Silver.

Lost Lake

Amanda Christmas produced and directed a short documentary released in February 2021 called Lost Lake.

"We found the history of Sumas Lake and we were blown away that we'd never heard about this in our school system," said Christmas.

Christmas said her research found that if the Barrowtown pumps stopped working, the original lake area would fill up within 48 hours. This would displace around 3,400 residents, according to the documentary.

The documentary which had about 700 views on YouTube on Tuesday morning, had almost 29,000 as of Friday. Much of the research for the film was based on the book Before we Lost the Lake by Chad Reimer.
