Dive Site Overview
Exploring the historical B-29 Bomber site offers divers a profound encounter with a relic of aviation history, submerged in Lake Mead. Originally used for target practice by NAVY pilots during WWII, the bomber eventually settled to the lake bottom.
Its significant size, traversing an 87-foot float line to the tail section with a total length requiring a 420-foot swim along the plane, creates an extensive exploration opportunity. Due to the sensitive nature of the site, exceptional buoyancy and fin skills are paramount; disturbing the silt can reduce visibility for up to 24 hours. Divers must be at least Advanced Open Water certified, hold a Nitrox certification, and be completely familiar with all their equipment, including clipping off peripherals.
This site is exclusively guided, with dive leaders assessing diver suitability throughout the descent and approach.
Best Time to Dive
Planning a dive to the B-29 involves considering lake conditions and seasonal climate patterns for an optimal experience. Bottom water temperatures can reach 10-15°C (50-60°F) in winter and summer, respectively. From August through September, conditions are typically most favorable, with excellent dive scores, lower average wave heights around 0.45-0.49 m (1.5-1.6 ft), and lighter winds averaging 14-15 km/h (9 mph). Air temperatures during these months are also at their warmest, averaging 25.7-28.1°C (78-83°F). Notably, dives are not available during the month of October due to site restrictions. Rain levels are generally low year-round, with slightly higher averages in summer months.

Dive Experience & Conditions
Descending toward the B-29, divers immediately feel the crisp freshwater conditions characteristic of a lake dive. Visibility can be excellent, though it varies significantly if silt on the bomber or lake bed is disturbed, necessitating impeccable buoyancy. Encountering the immense silhouette of the B-29 is a powerful sensory experience, revealing the detailed structure of the aircraft at depths varying from 29-38 m (95-125 ft). The water temperature, ranging from 10-15°C (50-60°F), demands appropriate thermal protection. Navigating the traverse line to the wreck and exploring its length requires diligent finning techniques to avoid contact with the fragile environment.
Dive Difficulty & Safety Guidelines
Approaching the B-29 site demands adherence to strict safety protocols and prerequisite skills. Divers must possess Advanced Open Water and Nitrox certifications, and strong buoyancy control is a non-negotiable requirement. Any contact with the B-29 or the lake bottom will result in an immediate termination of the dive without refund. Prior to diving, all participants are required to view a National Park Service video covering the site's history and specific guidelines. All dive peripherals, such as flashlights, must be securely clipped to your BCD to prevent accidental drops or contact with the aircraft. Dive guides maintain the authority to end a dive at any moment should diver suitability or adherence to rules become an issue.
