Most minor rivers are not included in the monitoring program implemented by the government services though they play an important economic role and form the basis of the hydrographic network. In this context, the optimization of the system of surface water monitoring based on the restored practices of hydrological and hydrochemical observations on minor rivers should be considered to be an essential element in the system of measures for the protection and rational use of water resources. The research goal is to develop a local monitoring system on the Butun (Kolyvan) River in the Pavlovskiy District of the Altai Region. The reconnaissance survey of the Butun River was carried out and surface water samples were taken for the purpose of developing the local monitoring program. The hydrographic and hydrological characteristics of the water body were investigated. The intra-annual flow distribution of the Butun River is calculated according to the generalized flow distribution pattern for the minor rivers of the Altai Region for the years with different water content. The calculations show that there is practically no flow, and the river discharge throughout the rainless period is less than the average annual discharge (Q 0 = 0.06 m 3 s). The water samples from the tail-bay and upgrade-stream side provide the data on water chemical composition. In terms of the chemical composition the water in the upgrade-stream side is hydrocarbonate magnesium fresh and weakly alkaline with the total hardness of 5.8 mg-eq dm 3. Downstream the chemical composition of the river water changes to bicarbonate-sulfate magnesium-sodium with the total hardness of 7.2 mg-eq dm 3. The proposals for the prevention of environmental degradation of the river, monitoring organization and development of timely water protection measures are presented.
