Watery Hall is a room in Metroid Prime in the Chozo Ruins. This room contains the Charge Beam which is blocked by a large gate and can only be opened by scanning the four Runic Symbols around the room and then a final one on the gate itself. After the Charge Beam is acquired, many Eyons on the walls activate and block the exit.

The water that covers the floor here is toxic before Flaahgra is defeated, so the high ledges along the walls must be used to reach the other end. A few lower ledges house Blastcaps and some crates, and a ledge underwater allows access to a Missile Expansion. There is a piece of Chozo Lore behind the Charge Beam that can be scanned; and, nearby, a Morph Ball hole in the wall is blocked with Sandstone. This leads to the Dynamo Access door.

A Secret World can be found in this room: [1]

Meteor Strike (NTSC version)
"Chozo script translated.
We have returned to Tallon IV, borne here against our will by a great cataclysm from the reaches of space. A meteor came, casting a dark shadow of debris over the land with the violence of its impact. Though we perceived this from beyond space and time, it was but a curiosity; a brief flare in the infinite march of the universe. But the meteor brought with it corruption. A Great Poison burst forth into the land, clawing at life with such violence that we were ripped from our peaceful state and find ourselves wandering as shadows of the mortal forms we left behind, searching for why we are here."
Meteor Strike (PAL version)
"Chozo script translated.
Unforeseen by sages, a meteor came as if from nowhere, casting a dark shadow of debris over the land with the violence of its impact. Its destructive force spent, the fallen star burned itself out rapidly, and the incident should have faded into memory...but the meteor brought with it corruption. A Great Poison burst forth into the land, a strange energy that clawed at natural life with a ferocity that seemed almost sentient. Bound by our ignorance of this phenomenon, we Chozo could only watch in horror as this dark force slowly began to spread across the surface of Tallon IV."

The Charge Beam

Charge Beam
This is reached by scanning four runic symbols and getting through the gate at the opposite end of the room.
Missile Expansion
To acquire this, the Gravity Suit is required. It is found by walking underwater, to a ledge roughly across from the Charge Beam's location. The expansion is found past this by jumping up it.
