Sumas border crossing closed due to flooding

Remember the flood of 2021? It was because they removed a diversion dam on the Nooksack River in the US resulting in more water moving north into Canada. So let's do the math. 100 year ago Abbotsford was a lake. So they built a dike and rerouted the water.  The US river carries water from Mount Baker to the Puget Sound near Bellingham, but when it breaches, the floodwater flows north towards the Sumas Prairie.

When they removed the diversion dam in the Nooksack River, that increased the flow of water in the Sumas River. As a result the dike was breached because they forgot to take into consideration the increase of water coming from the Nooksack River when they removed the diversion dam. So let's raise the dike and deal with it. It's not rocket science.  

​​​​​​​​​​​​​​​The Middle Fork Nooksack River Fish Passage project was completed in 2022, including the fish passage and dam removal portion of the project which was completed in 2020. The flood was the following year. 

"The Middle Fork was also partially blocked with a diversion dam built by the City of Bellingham in 1961 for diverting water into Lake Whatcom, Bellingham's drinking water supply. As of July 2020, this old water diversion system has been modified to remove the dam and restore the river channel for the benefit of critical salmon spawning habitat." More water flowing north. 

Never mind the diversion dam. It's climate change.
