|Concept art of Hoover Dam in Fallout: New Vegas.|
In 2274, Hoover Dam was taken by the New California Republic when the first NCR scouts arrived at Hoover Dam. This action spurred Mr. House into action as a sign of returning civilization. Mr. House then sent his Securitron army out onto the New Vegas Strip and rallied the tribals occupying the city, ensuring that when the NCR first reached New Vegas, they would return with stories of a city of lights in the middle of the desert, bringing in the tourist revenue required for Mr. House to carry forward his plans. He worried about the independence of his new city's power source, but fortunately the arrival of Caesar's Legion in the region meant that the NCR could not take the Dam and the Strip without significant casualties, which would leave them vulnerable to the Legion. Mr. House and the NCR drew up the New Vegas treaty, out of necessity more than anything. 95% of the Dam's power output would go to the NCR, and in return Vegas' independence would be guaranteed.
In 2277, the Legion, led by the Malpais Legate, briefly took the Dam, but were defeated shortly after when the NCR performed a tactical retreat to destroy the Legion by trapping them in Boulder City. After the Battles of Willow Beach and Arizona Spillway, the Dam stands as the only foothold the NCR has east of the Colorado. It is the central point of the power struggle between NCR, the Legion, and Mr. House, and with the Second Battle of Hoover Dam on the horizon, it is certain that the outcome will determine the fate of the entire Mojave Wasteland.
While troopers are active here, there are also a large number of civilian contractors who are trying to keep the dam running. They are of a secondary concern to Moore, who is preparing for an impending attack by Caesar and a visit by President Kimball.
Hoover Dam covers a large area with extensive exterior and interior sections, despite there only being one map marker for the entire location. Following the Colorado River downstream (or coming upstream from Cottonwood Cove), the player will encounter a pontoon barrier presumably to keep the Legion at bay.
The west side of the dam is controlled by the NCR and features the anti-aircraft gun seen on billboards. The fast-travel map marker puts the player just outside of the entrance to the Hoover Dam visitor center. Just north of the visitor center building is a stage and viewing area. To the west of the stage is a large anti-aircraft cannon. Continuing north along the barricaded road leads to the top of the dam itself. Two towers are along the south edge of the road. Access to Hoover Dam Intake Tower 01 and 02 is via a bridge connected to the north side of the road. The road ends at a checkpoint door which is inaccessible until the final quest, such as Eureka! The checkpoint contains a Very Hard locked terminal, and a few lockers with minor loot. It also houses a small sniper nest on the roof, accessible via a ladder.
Access to the north and south bases of the dam are blocked off by a pontoon barrier when attempting to swim downriver toward it. Pontoons hold sections of chain link fence in place along the top of the water, while weights keep the submerged ends in place and the whole structure taut. While it is possible to get above the top of the chain link fence from the water, invisible barriers prevent you from actually hopping over it, even when attempted from the cliffs far above the barrier; though it is possible to jump off the north side of the dam into the water. This places the player on the opposite side of the pontoon barrier and allows the player to swim the length of the Hoover Dam. A one-way ladder upwards is available to return to the top of the dam on the NCR side of the river.
The east side of the dam is controlled by the Legion. Going west along the barricaded road leads to the top of the dam itself. Access to Hoover Dam Intake Tower 03 and 04 is via a bridge connected to the north side of the road. There are two towers along the south edge of the road, one is ruined.
The south base of the dam is accessible by descending through interior sections of the dam and exiting from the second tier of either Hoover Dam Power Plant 02 or 04. There are spectacular gushers of water from outflow pipes high up on the east and west walls of the river canyon. You can swim from the west to the east side and climb up on the concrete area by swimming all the way to the south end and walking up the sandbar to the southeast corner.
See the individual buildings and sections for descriptions of the dam interior.
- Snow globe - Hoover Dam - central reception desk in the visitor center.
- Two Chinese stealth armors - Hoover Dam offices, radioactive barrel storage in the middle stack of crates.
- President Kimball's suit - can be looted off his corpse during the quests Arizona Killer or You'll Know It When It Happens.
- General Oliver's uniform - can be looted off his corpse during the quest Veni, Vidi, Vici and No Gods, No Masters.
- 12 frag grenades - in a locker in intake tower 2.
- It is one of the few locations with outside fresh water as well as inside.
- Mike Lawson talks about repairing the non-functional dam turbines and even though the Courier can swim down to reach the turbines, the game never makes the repairs an option for quests.
- If the Courier jumps on the artillery cannon, run down the barrel and jump, he/she can go past the game's barrier and go to the bottom of Hoover Dam. Just save before you hit the ground, then load. Facing the direction of the river, if the Courier goes on the right side, he/she can find a door to the Hoover Dam Power Plant 2 and a door leading to Power Plant 4. Otherwise this area of the map is inaccessible. (There is an "exit door" in the North East corner of plant 02 and 04, behind metal stairway which ascends west to top of generator, that can be used to exit to the spillway.) One of these doors is also used in the final quest.
- During the battle at Hoover Dam, most non-player characters wear masks. This has been  motivated by J.E.Sawyer as an attempt to reduce memory usage, since "FaceGen/FaceFX data can be expensive". These masks look like recruit helmets.
- When on top of the first sniper tower, the Courier can lock and unlock the ladder. However, it can be used either way.
- If the Courier jumps down from the Hoover Dam into the water on the north side, and swims as far east as possible until he/she can't jump/walk any further, the Courier may begin to hear artillery fire and flying shells even though he/she has not started the battle at Hoover Dam. In addition to the sound effects, the theme music of Hoover Dam will change to the version heard in one of the end game quests.
- The NCR rangers walking on the dam do not actually wear NCR Ranger patrol armor, but a lower resolution type of clothing that is only for aesthetic purposes, the insignia on the shoulder is blurry, the water pack on their backs is flat, and rifle-grip weapons do not change position when holstered. Much like the face masks worn by troopers, the armor cannot be looted from their inventory.
- If the Courier jumps off the north side of Hoover Dam and returns to the top of the Dam, the game may glitch and cause things like the artillery cannon to completely disappear and the texture for the road in front of the visitor center to change.
- There are invisible walls around the area where Kimball speaks. This may result in his body coming back because he bounced off the wall (if exploded and killed, as ragdoll physics will take over).
- Arcade Gannon will make some comments about the Dam when first brought to the area.
- The Hoover Dam, in real life, is actually much smaller than the game version.
Behind the scenesEdit
On the side of one of the stone guard towers is a banner reading, "LEGION GO HOME". This is a reference to the real life slogan "Ami go home", originally a protest from European communists against US occupiers after WWII, later adopted by European peace movements during the Vietnam war and more recently the gulf wars.
The other side of this is a reference to the film Monty Python's Life of Brian wherein the main character writes "Romanes eunt domus", grammatically incorrect for "Romans, go home." He is later corrected by an Imperial guardsman.
