Question
Does anybody know why we see water with blue color in a river or a lake and when we catch it with a glass doesn’t have color?

Answer
Hi

The color of a large body of water is derived from the fact that the water gradually filters out parts of the color spectrum, leaving only that which penetrates furthest. This only happens when there is sufficient water to do the filtering.

A glass of water does not have the capacity to filter out much of anything - therefore you do not see any particular color.
