Constructed in 1910, this Earth-type dam stands at 19 feet tall and spans 550 feet in length, with a maximum storage capacity of 345 acre-feet. Despite its age, the reservoir's primary purpose of irrigation remains vital for supporting agricultural activities in the region.
With a surface area of 23 acres and a drainage area of 0.56 square miles, the Mauka Reservoir plays a crucial role in water resource management on the island of Kauai. However, recent assessments have rated the dam's condition as poor, posing a high hazard potential. Emergency action plans are in place, with the last inspection conducted in April 2018. As climate change continues to impact water availability and storage infrastructure, the Mauka Reservoir serves as a reminder of the importance of maintaining and upgrading essential water resources to ensure resilience in the face of evolving environmental challenges.
