About this map

Volcanic activity and water management define this portion of the Kau District on the Island of Hawaii. The landscape is sharply divided between the dense vegetation of the Kaalaala Forest Reserve and the stark, open expanse of the Lava Flow of 1926. The geologic history of the area is further evidenced by a prominent Lava Flow Line and numerous named puus, such as Puu Kinikini and Hionamoa.

Resource development in this arid and shifting environment is visible through a network of water features and infrastructure. The Keaiwa Reservoir serves as a vital catchment, supported by the Maunaanu Waterhole and the Noguchi Tunnel near the eastern boundary. A system of flumes and a Water Tank near Punaluu Kahawai illustrate the complex efforts to direct water across the Kopu Moaula Gulch and other deep ravines. Isolated Jeep Trails provide the only significant access through the rugged slopes of Kahuku and Kapapala.
