===Geography and ecology===
[[File:H5G Fathom Ocean.png|thumb|right|300px|A paelosur in Beta Gabriel's oceans.]]
Water is found throughout the [[Milky Way|galaxy]] across many [[planet]]s within a variety of climates; water on these worlds can be found in the form of streams, rivers, ponds, [[:Category:Bodies of water|larger bodies]] like lakes and seas, and even in the form of ice. [[Forerunner]] installations such as [[shield world]]s and [[Halo Array|Halo installation]]s also commonly include these geographical features despite their artificial nature.{{Ref/Level|Id=DeltaHalo|H2|[[Delta Halo]]}}{{Ref/Level|Id=Covenant|H3|[[The Covenant (level)]]}}{{Ref/Level|Id=ShieldWorld|HW|[[Shield World (level)]]}} Many beings found on both natural and artificial worlds live predominately in the water, such as [[sea worm]]s and [[paelosur]]s.{{Ref/Level|Id=SilentCart|HCE|[[The Silent Cartographer]]}}{{Ref/Site|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-fauna-getaway|Site=Halo Waypoint|Page=Canon Fodder - Fauna Getaway}} Even among the creatures that do not live within it, many terrestrial creatures are known to drink water.{{Ref/Marketing|Id=HIT|HINF|[[Halo Infinite announcement trailer|''Halo Infinite'' announcement trailer]]|Detail=[[Deer and deer-like creatures|Deer]] drinking water.}}{{Ref/Novel|Id=HHITD18|HitD|Chapter=18}}

===Uses===
Sentient species utilize water for a number of purposes. [[Human]]s have developed [[Human marine craft|vehicles specifically to traverse]] those water bodies, even creating seaborne warships such as the {{Class|Crassus|supercarrier}}.{{Ref/Site|Id=CFStrike|URL=https://www.halowaypoint.com/news/canon-fodder-ship-strike|Site=Halo Waypoint|Page=Canon Fodder - Ship Strike|D=20|M=04|Y=2023}} Water is often used by humans for drinking, and water products like [[H2Oh!

==Gameplay==
Water is a common sight in every ''Halo'' game, from ''[[Halo: Combat Evolved]]'' to ''[[Halo Infinite]]''. In ''[[Halo 3]]'' and ''[[Halo: Reach]]'', bodies and many objects will float on water for a while before sinking.

Water is often utilized as a death barrier in some maps and the player is killed upon hitting the water or when hitting the water becomes inevitable. However, in some cases on [[Forge World]] and [[Forge Island]], there are a few water areas that will not kill the player should they enter them.
