Muddy floodwaters, unleashed by severe rains, have submerged streets, displaced homes, and claimed vehicles across Oahu's North Shore. Officials issued mandatory evacuation orders for thousands of residents, particularly in the towns of Haleiwa and Waialua, on Friday, citing the "imminent failure" of the century-old Wahiawa Dam. The dam, reportedly in poor condition and needing repairs for years, is currently under intense scrutiny as water levels rise, with some reports indicating water actively running over its spillway. Emergency services have reported rescuing approximately 230 individuals caught in the deluge, with floodwaters reaching chest-high in some areas. No fatalities have been confirmed thus far.

CRISIS UNFOLDING ON OAHU

The situation escalated on Friday, March 21, 2026, when Honolulu officials issued a "LEAVE NOW" evacuation order for Waialua and Haleiwa, detailing "extremely dangerous flooding and Wahiawa Dam is high." This directive covered over 4,000 people, though the actual number could be higher. The Honolulu Department of Emergency Management spokesperson, Molly Pierce, confirmed the scale of the evacuation. Firefighters and lifeguards have been actively involved in rescue operations using jet skis to navigate the treacherous, chest-deep floodwaters.

A DAM OF CONCERN

The Wahiawa Dam, a structure dating back 120 years, has been a source of apprehension for local residents during periods of heavy rainfall. Reports suggest the dam's poor condition has been a known issue for years. Officials had previously flagged the dam during a storm the prior week, which triggered widespread flooding that destroyed roads and homes. While water levels receded then, the recent deluge has brought renewed concerns to a head. Historical records indicate that following repairs to the spillway to meet safety standards, Dole had proposed donating the dam, reservoir, and associated ditch system to the state.
