The lake has several small islands, the largest being Ol Kokwe Island. Ol Kokwe, an extinct volcanic centre related to Korosi volcano north of the lake, has several hot springs and fumaroles, some of which have precipitated sulfur deposits. A group of hot springs discharge along the shoreline at Soro near the northeastern corner of the island.
