“Tiger Dam” under construction on Highway 1 in Abbotsford to hold back flood water – Abbotsford News – .


The Ministry of Transportation and Infrastructure is building a “Tiger Dam” on Route 1 Sunday evening (November 28) in an attempt to keep floodwaters in the Sumas River.

The Abbotsford Police Department (APD) posted on social media around 6 p.m. Sunday that Highway 1 between Abbotsford and Chilliwack is closed to all traffic, including emergency, essential and construction vehicles.

“A dam is being built and no access will be possible,” said the letter.

APD media spokesman Paul Walker told The Abbotsford News that the Tiger Dam is positioned across Route 1 near the Cole Road area.

This type of dam is a series of tubes filled with water over a meter high that create a barrier.

It is carried out on flat ground and anchored in the roadway at regular intervals along the dam.

Walker describes it as similar to “a big giant sandbag”. He didn’t know how long the roadblock would last or how long it could be in place.

He said it was built near Cole Road because that area is lower than the parts to the west of there.

“So the water would usually pour over there, but it was too full. So they’re trying to keep it from spitting and keep it in the canal, ”Walker said.

Water from the Sumas River goes to the Barrowtown Pumping Station, where it is piped into the Fraser River.

No further information on the Tiger Dam, including why the option was not used earlier or in other locations, was available at this time.

Earlier on Sunday, the city said the valves at the pumping station had to be closed, which happens when the level of the Fraser River is not low enough.

It was also reported on Sunday afternoon that the Nooksack River in the United States had overflowed and water was heading towards Abbotsford, where an evacuation order had been issued for the village of Huntingdon.
