Built in 1985 by the USDA NRCS, this Earth-type dam stands at a height of 37 feet and stretches over 560 feet in length. With a storage capacity of 17 acre-feet, the reservoir primarily serves the purpose of irrigation, supporting agricultural activities in the region.
Despite its modest size of 1.3 acres, Puu Koa Reservoir plays a crucial role in water resource management in the area, especially during periods of dry weather. The dam's uncontrolled spillway and fair condition assessment make it a key infrastructure for mitigating potential flood risks and ensuring a stable water supply for local farmers. The reservoir's high hazard potential is offset by its moderate risk assessment rating, indicating a balance between the benefits it provides and the level of risk it poses.
The reservoir is under state jurisdiction and regulation, with inspections conducted regularly to ensure its structural integrity and operational efficiency. With its strategic location and significant contribution to the local irrigation system, Puu Koa Reservoir stands as a testament to sustainable water resource management in the face of changing climate patterns and increasing water demands.
