The collapse of the flood berm allowed flood waters to surround the auxiliary and containment buildings at the plant, and also forced the temporary transfer of power from the external electricity grid to backup electrical generators. It was reported more than 2 feet (0.61 m) of water rushed in around buildings and electrical transformers. Backup generators were then used to ensure the facility maintained electrical power for cooling. The rupturing of the flood berm also resulted in approximately 100 US gallons (380 L; 83 imp gal) of petroleum being released into the river as many fuel containers were washed out. The fuel/oil containers were staged around the facility to supply fuel for pumps which remove water within the flood containment barriers. The rubber berm was a secondary measure not mandated by the NRC and was put in place by OPPD to provide additional room for work immediately outside the reactor buildings. According to the NRC, the water-filled berm "protects several pieces of equipment that have been brought onsite, including an additional emergency diesel generator for supplying AC electrical power, water pumps, firefighting equipment and sandbagging supplies". On July 11 OPPD installed a new 8-foot (2.4 m) inflatable berm as a replacement.

facility was not adequately prepared for a "worst-case" flooding scenario. A number of potential flood water penetration points were discovered that could have impacted the raw feed water supply to the cooling system, the auxiliary water supply and main switchgear (electrical) room. By early 2011, corrective measures had been implemented. In 2009 the NRC did a flood risk assessment which found that the protection measures were only designed to handle floods to 1,009 feet (308 m) above sea level which was below the NRC mandated elevation of 1,014 feet (309 m) for the plant. The risk assessment stated that at 1,010 feet (310 m), flooding would have "led to a 100 percent chance of a fuel damage if the emergency gasoline pumps didn't work."
