The performance of river quality should always be observed in the river conservation. In this study the quality of river water is depicted from the rate of carbon deoxygenation. The rate of carbon deoxygenation indicates the speed of the dissolved oxygen consumption of the stream for the biochemical process of organic matter. Its value depends on the content of organic matter and the availability of oxygen from the reaeration capability of the stream. This research was conducted on the Metro River from Sukun sub-district of Malang to Kepanjen Sub-district, Malang Regency which is divided into 5 (five) segments. The method of determining carbon deoxygenation rate using Thomas method. The highest rate of carbon deoxygenation (kd) occurs in 4 th segment of 0.63 / day, while the smallest is in 2 nd segment of 0.48/day. The carbon dioxygenation rate in Metro River is higher than Brantas River of Malang City, Upper Citarum River, Cikapundung River and Citepus River. This shows that Metro River has better self-purification capability so that its quality is better
