No significant changes were observed during today's visit to monitor Kīlauea's summit water lake. The lake surface exhibited some interesting color variations today, but within the range of those previously observed. The sharp color boundary between tan and brown zones has been common. Today, a wedge-shaped, slightly greenish zone was present in the west portion of the lake (towards bottom of image). Laser rangefinder measurements indicate that the lake continues to slowly rise.

In the eastern portion of the lake, the dark brown zone had a slightly mottled appearance, but this pattern was transient and gone within about ten minutes.

This photo of Kīlauea's summit water lake was taken from the KWcam webcam site on the western caldera rim. The sharp color boundary between tan and dark brown zones is easily visible. A small greenish zone in the west end of the lake (bottom right of image) was more conspicuous today. These zones of greenish water correspond with areas of higher temperatures in the thermal imagery, and may represent zones of water influx into the lake. USGS photo by M. Patrick.
