How to estimate the volume and the surface area of the lake

You can find the volume by doing L x W x H = V because it looks closest to a rectangular prism.

You can also find the SA by L x W.

You can estimate the SA by measuring the length and width of the lake.

Then draw a rectangle around the lake and then do L x W with the numbers you got from the lake.

Then divide your answer by half  because the area of the lake looks like it takes half the square.

Then use the SA you have and multiply by the depth of the lake to get the volume.

How much water does the Barrier contain behind it in the lake

I’m using the surface area and depth Wikipedia has.

Then you convert the km into m.

Then you multiply.

Then turn it into Liters

There are 1182860000000L of water

If the Barrier faulted

If the Barrier faulted, then more than half of all the water would be rushing down the mountain and it would destroy mostly everything it runs into. It will have 200x more energy than the bomb on Hiroshima and the provincial government declared the area below Garibaldi lake unsafe for living. I think a lot of damage is gonna be done around the area of the lake and all that water would have to settle in the ocean or somewhere else.
