SUMMARY. 1. Lake Goang has a pH of 2.5. Associated with this low pH are high concentrations of sulphate, chloride, iron and aluminium. There are no fish in the lake. 2. A single species of Heterococcales was found in the phytoplankton. 3. The zooplankton consists of one species of rotifer and a stalked species of Vorticella. 4. The shallow water fauna consists of two species of nematodes, at least two larval Diptera, one trichopteran, a zygopteran, a small crab ( Sundatelphusa ) and a cyclopoid copepod ( Paracyclops ). 5. During January an oily slick appears and is deposited as asphalt around the shore of the lake.
