From Halopedia, the Halo wiki
Waterfront is a Firefight map in Halo: Reach. It is set at night, in a pumping station beside a body of water near the Ütközet dam in the Viery Territory. The map is based on a section of the campaign level Nightfall.
Waterfront is a medium-small sized, industrial themed Firefight map. The map contains a series of buildings positioned in a circular pattern around a central opening with several ramps leading down to the water basins where the Covenant are usually dropped down. The complex is connected to the land by a covered bridge which offers great protection from airborne enemy fire. Phantom dropships drop off waves of enemies in a 360 degree circle around the map, which forces players to defend the middle buildings more. The main hazards on this map are the Jackal snipers on the hill.
The following are known locations on the map that are so named on the player's heads-up display during gameplay:
