1983 Map of Waialeale

About this map

The massive volcanic peak of Waialeale and the adjacent Kawaikini summit dominate this interior Kauai landscape, serving as the central watershed for the island. In this 1983 edition, the intricate hydrologic network is visible through the many streams radiating from the high peaks, including the Hanalei River and the North Fork Wailua River. Of particular interest for researchers of island infrastructure is the series of industrial water features, such as the Upper Powerhouse, Lower Powerhouse, and various aqueduct and ditch systems that divert water for power and agriculture. The map also delineates the transition from the high-elevation Alakai Swamp to the dramatic depths of Olokele Canyon. This survey captures the remote interior during a period of ongoing hydrological management, evidenced by the numerous gaging stations and rain gages positioned across the mountains.
