Built in 1910 for irrigation purposes, this Earth dam stands at a height of 46 feet and has a maximum storage capacity of 420 acre-feet. The reservoir covers a surface area of 14.1 acres and is fed by the offstream flow of the Kealia Stream.
Despite its historical significance, Kaneha Reservoir poses a high hazard potential with a poor condition assessment, prompting regular inspections every five years. The spillway, with a width of 20 feet, is uncontrolled, adding to the risk factor. The reservoir's risk assessment has been classified as moderate, indicating a need for proactive risk management measures to ensure public safety and long-term sustainability.
With a congressman representing the area and a designated state agency overseeing regulation and enforcement, Kaneha Reservoir serves as a critical water source for irrigation in Kauai, Hawaii. As climate change continues to impact water resources, the management and maintenance of such vital infrastructure are paramount to ensure the resilience and safety of communities reliant on this essential resource.
