Lake Dissoni, also known as Lake Soden, is a small lake in the volcanic chain in the Southwest Region of Cameroon. This volcanic lake has diameter of about 1.25 km (0.78 mi) and is at the southeastern foot of the Rumpi Hills.[1]

There are only three fish species in the lake, but all these are endemic: A poeciliid (Procatopus lacustris, though probably a synonym of the more widespread P. similis[2]), an undescribed catfish (Clarias sp.) and an undescribed barb (Barbus sp.).[3] The atyid shrimp Caridina sodenensis is also endemic to the lake.[4]
