Heavy rain causes flooding, 5,500 residents evacuated
Recent heavy rainfall has led to significant flooding on O'ahu's North Shore, prompting the evacuation of approximately 5,500 residents. The primary cause for concern is the Wahiawa Dam, a 120-year-old structure located in Central O'ahu. The dam's water levels have fluctuated dramatically, peaking at over 85 feet, close to its maximum capacity, before receding slightly to 81.5 feet. The Wahiawa Dam, originally built in 1906 for sugar production, is now classified as a high-hazard dam, meaning its failure would likely result in loss of life.
