The Fraser Valley is home to some of Canada’s most important agricultural land, but 100 years ago this region was a huge glacial lake and the center of the Semá:th people’s food system. “The lake provided everything that the Nations needed,” says Troy Ganzeveld, councilor for the Semá:th Nation. The area now faces an uncertain future, as current residents of the lakebed struggle to keep it dry, and the lake fights to return. In response, the Semá:th people and researchers are calling for the lake’s restoration to address the harms of the past while adapting to future climate change. Semá:th Xhotsa, also known as Sumas Lake, was located in what is today the Lower Fraser Valley of British Columbia province. First Nations’ food systems relied directly on the lake. There were ducks, geese, salmon, sturgeon, clams, wild hazelnuts and strawberries. Residents traveled on the lake by canoe to hunt deer and elk on islands. For the Semá:th people, the lake was the primary source of food and central to their culture as a gathering place. European settlers began to occupy British Columbia in the 1850s, taking land to establish European-style agriculture. By the 1920s, the colonists had developed a plan to drain Semá:th Xhotsa to create farmland, and by 1924 the lake was drained into a human-made canal and the nearby Fraser River. Over the past century, the region has changed dramatically: less than 30% of the native vegetation remains, and more than 85% of floodplain habitat and 64% of…This article was originally published on Mongabay
