This photo was taken just a couple of days ago. The complications and challenges posed by such an event have escalated but the Communities of Chilliwack and Abbotsford have rallied together to help each other out. From loading animals on boats, to sandbagging, to putting people up in their homes, and close to 300 people swarming to the Barrowtown Pump station to work to keep it going just a another day, to allow it to do its job when the flood levels - well levelled out. It is a beautiful story of humanity. The aftermath, is still not over and the clean up and re-build is not over but I know that the people in the Fraser Valley will rally together to make it happen. Obviously there is more details to come...Why did this happen? The drainage systems have been working and keeping the water at bay for over 100 years! See the bullet point history of the Sumas Flats region and the engineering feats achieved back in the Early part of the 1900's courtesy of the Chilliwack Progress below...

Once a fertile lake for local Indigenous life, European settlers drained Sumas Lake in the early 20th century to transform the shallow bed into the region’s agricultural powerhouse.Here are some quick facts about Sumas Lake and its history:
- Sumas Lake was formed by receding glaciers more than 8,000 years ago.
- The large lake between Abbotsford and Chilliwack was settled by the Sema:th peoples as far back as 400 BC, with a large community living there in the mid-1840s.
- Europeans began moving to the region in large numbers in the early 1900s. Homesteaders disliked the lake’s characteristics (regular flooding, shallow wetlands, swamps, mosquitoes) for farming.
- Sumas Lake was drained and the Vedder canal was built in the early 1920s, using a pump station to divert the lake’s in-flowing rivers for irrigation and allow European farmers to access the fertile soil. It was described as an engineering marvel at the time.
- Over the next 10 years, thousands of acres of some of the most productive farmland was created in the Lower Mainland.
- Barrowtown Pump Station was built in the early 1980s for $27 million. It’s the second busiest pump station in North America; four pump engines running full tilt can pump 500,000 gallons of water a minute.
- The Nooksack River breached in 1990, swamping the Whatcom Road interchange and the western portions of Sumas Prairie, and shutting down all traffic on Highway 1 for 26 hours
- The U.S. river carries water from Mount Baker to the Puget Sound near Bellingham, but when it breaches, the floodwater flows north towards the Sumas Prairie
- An international task force was created after the 1990 event to try and prevent a future disaster from occurring, but was inactive from 2011 to 2018. It was called a one-in-35-year event.
- One 1995 study found that a larger “avulsion” flood event could change the course of the river permanently, diverting its flow north into the former Sumas Lake, draining into the Fraser River
- A new task force was formed with provincial officials in 2019, with the City of Abbotsford being granted $250,000 in federal monies a study looking at past data to develop a plan to mitigate flooding. The study was meant to open discussions with U.S. officials on how to manage Nooksack.
