Ice–Not so Nice

Gorgeous shot — thank you to Rhonda for sending this in. You are looking at the Medicine River near the beautiful town of Eckville (just west of Sylvan Lake).
The ice on the river got me thinking about the ice jams and floods in Manitoba. Thankfully, we are not dealing with problems like that “here” in Alberta. But there, huge blocks of ice are preventing and obstructing the flow of water. Everything gets backed up - causing the flooding.
Ice jams are influenced by: Snowpack, How the ice was created on the river and its banks, How the river flows, and Weather.
Jams form during freeze-up and breakup,…but the worst flooding is usually caused by the breakup jams.
Here’s a great webpage to look at, if you want to learn more about the science of ice and how it puts the river and humans — in a JAM!

These 2 pictures are from Manitoba. Selkirk is about 40k north of Winnipeg. Morris about 50k south.
