Effects of Surface-Water Diversions on Habitat Availability for Native Macrofauna, Northeast Maui, Hawaii

Effects of surface-water diversions on habitat availability for native stream fauna (fish, shrimp, and snails) are described for 21 streams in northeast Maui, Hawaii. Five streams (Waikamoi, Honomanu, Wailuanui, Kopiliula, and Hanawi Streams) were chosen as representative streams for intensive study. On each of the five streams, three...

Availability and Distribution of Base Flow in Lower Honokohau Stream, Island of Maui

Honokohau Stream is one of the few perennial streams in the Lahaina District of West Maui. Current Honokohau water-use practices often lead to conflicts among water users, which are most evident during periods of base flow. To better manage the resource, data are needed that describe the availability and distribution of base flow in lower...

For several years, a special ultraviolet camera has been located near Keanakākoʻi Crater at Kīlauea's summit. The camera was capable of detecting SO2 gas coming from Halema‘uma‘u crater. This morning, the camera was removed because there is very little SO2 to measure these days at the summit. In addition, cracking near Keanakākoʻi Crater was making access difficult.
