To repeat what I posted on the Canadian forum: Sumas Prairie flooding like this shouldn’t be a super-big surprise… it used to be Sumas Lake before the Vedder Canal and the Sumas Drainage Canal were dug to drain it. Due to those canals getting overwhelmed, Sumas Lake is simply making a temporary comeback.

I guess you could say that about nearly every river in the PNW.  Most have some sort of dyke for flood control and many of them have houses and infrastructure built in their floodplain

Brief update. This is a copy paste from social media because my battery is almost dead. But yeah, the situation in Abbotsford affects me because my house sits right around the edge of former Sumas Lake during flood season (it expanded and contracted a lot throughout the seasons).

We have heard the rumors of the potential failure of the Yarrow Pumps and subsequent inundation of the Sumas Prairie. We have also heard that there are positive signs on the Fraser River that failure might not be imminent. We are choosing to remain positive that our house will not be affected. Nevertheless, we made the decision to be evacuated around 10 o'clock tonight primarily because, with all north-south streets in Sumas still under water to the west, the only escape route out of our neighborhood was to head east, toward the prairie. So we had to do it now, or we wouldn't have a chance later. It was quite surreal to look across the field at the Canadian side, and see a stream of headlights heading west, fleeing the prairie.

We are now safe with family on high ground far away from the flooding.

Wow. What a crazy situation and so unnerving, stressful. Glad y'all are safe!

The City of Abbotsford, which runs the Barrowtown pumping station, expects it to flood and fail soon. It can't keep up with the inflow and is slowly losing the battle.

It's called clown range for a reason.

That will be very bad. Wouldn't the Fraser river flood southwestward into the Sumas River and maybe eastern parts of Abbotsford? I dunno this area at all or if that would run downhill from Barrowtown to Abbotsford?

Temps still hanging in the upper 30s here…usually it takes awhile to cool off and then the temps plummet a couple hours before sunrise. Still thinking 32-34 here tomorrow morning.

Slightly off-topic, but well it is wind related, so I guess not.

I'm wondering if anyone knows what the strongest winds those Christmas inflatables can endure without being torn apart and ruined? I have it tethered to the ground really well.

27.5* down here this morning. Everything has that frost sparkle and the grass is crunchy! 

Also, someone asked about inflatable decorations and wind.....We had our spider get tossed around in the winds right before Halloween. I thought I had it tethered well.....I did not. I do not think it's broken or torn up, I didn't check, just said "Oh Well" and stuffed it back into the box. lol

Also SeaTac got down to 31°F last night, giving Seattle its first “official” freeze of the season!
