How deep does water have to be to prevent fall damage?

Question

I have a very deep vertical mine shaft (I started in a mountain and hit bedrock), so it takes a long time to get up or down using my ladder. To speed up the trip down I thought "why don't I add a little pool for me to jump in?", but when testing it out the first time I died and had to rush back to my mine to collect my items before they disappeared.

How deep do I have to make the pool in order to prevent myself from taking damage when I hit the water?

Answer

It has to be at least 3 deep to survive a fall from surface to bedrock
