The name of the stunt is a Free Fall. As opposed to using a bungee cord or parachute or cable restraint mechanism, a Free Fall stunt uses only a air bag or other type of landing platform to protect the stuntman from certain squishy death. As water does not compress, a pool is not well suited for very high jumps, especially when it's not a perfect dive. Falling into water from X height is like falling into pavement from X/3 height, as demonstrated on Myth Busters.
As mentioned above, the highest movie free fall is in Sharkey's at 220 feet. 35 years later, the next highest was 125 feet in this year's Assassin's Creed movie.
Both of these are dwarfed by non-cinematic stunts. The same stuntman from Sharkey's did a 313 foot drop from a helicopter. And a few months ago, there was a 25,000 foot Free Fall into a custom designed 10,000 square foot net.
