O‘AHU: Spillway at Nu‘uanu Dam Nears Capacity From Olivia RainsSeptember 13, 2018, 10:59 AM HST · Updated September 13, 12:01 PM 2 Comments
The Nuʻuanu Dam #1 is about a 1.5 feet below the spillway due to the amount of rain brought on by former Tropical Storm Olivia.
The Honolulu Board of Water Supply has been monitoring and siphoning the excess water from the reservoir since the beginning of the week to keep the water level below the spillway; however, with the passing of Olivia, the rain exceeded the siphoning capacity.
Department personnel and crews from the Honolulu Fire Department are currently deployed at the dam with water pumps to bring the level of the reservoir down further.
