Finding the volume of Garibaldi Lake
The first part of this assignment is to find the volume of the lake and how much water is being held up by the dam.
Using the formula for a rough estimate use surface area X average depth.
9.94km^2 X 119m
Next the 9.94km^2 needs to be converted into meters
=9.94 X 10^6 = 9 940 000m^2
Now that they are in the same unit we will go back to the original formula (SA X H)
=9 940 000^2 X 119m = 1 182 860 000m^3
Since we are measuring the amount of water we must convert it into liters from cubed meters and the ratio of this is 1m^3=1000L
=1 182 860 000 X 1000 = 1 182 860 000 000L
So there is about 1 182 860 000 000L in Garibaldi Lake.
What would happen if the dam fell?
If the dam fell I think almost of the water would escape really fast and there would be tons of pressure pushing it out and the water would go out to at least the level of the dam that is left over and because the wall just fell I would expect huge waves that would make more water go out from the current and force pushing outwards from underneath the surface. If the dam broke it would flood much of the nearby valleys and into the city of Squamish. This would affect lots of people homes and businesses and be a big disaster if this happened.
