The reservoir has a storage capacity of 85 acre-feet and covers a surface area of 3.2 acres, serving as a vital water source for agricultural activities in the region. The dam is designed with a buttress core type and has a height of 32 feet, with a hydraulic height of 34 feet and a structural height of 40 feet.
Despite its importance for irrigation, Kepani Reservoir has been rated as having a high hazard potential and poor condition assessment, indicating a need for maintenance and potential safety improvements. The dam is regulated by the DLNR in Hawaii and is subject to regular inspections and enforcement measures. In the event of an emergency, the reservoir lacks an Emergency Action Plan (EAP) preparedness and may require further risk management measures to ensure the safety of surrounding communities and infrastructure.
Located on the Makaweli River offstream, Kepani Reservoir plays a crucial role in supporting agricultural activities in the region. However, its current condition and hazard potential highlight the importance of prioritizing maintenance and safety measures to ensure the sustainable management of water resources and climate resilience in the area.
