Purpose: to develop the main stages of planning the measures of engineering and environmental protection of water bodies – drainage water inlets from irrigated lands. Materials and methods. When developing the stages of planning the measures of engineering and environmental protection of water bodies, recommendations for assessing the environmental and economic efficiency of investment projects for agricultural land reclamation and methods for calculating environmental payments necessary to take into account the effectiveness of environmental protective measures were used. Results. Planning the measures of engineering and environmental protection of a water body can be conditionally divided into four stages. At the first stage, the comprehensive monitoring studies of the water system and agrolandscape in the river catchment basin are carried out. The second stage consists of conducting their comprehensive environmental assessment, including the calculation of such indicators as the combinatorial index of water pollution, the indicator of anthropogenic water body load, the total indicator of soil pollution, bottom deposits, the soil loss rate, the soil formation rate, soil salinization, sodium, magnesium alkalinization, as well as the calculation of cost environmental indicators. At the third stage, a set of measures for engineering and environmental protection of a water body is developed, and at the fourth, a quantitative assessment of the effectiveness of the proposed measures is carried out. Conclusion. Environmental indicators that quantitatively characterize the anthropogenic load on water bodies as a result of the irrigation system operation are proposed. A methodical approach is proposed and the main stages of planning the engineering and environmental protection of water bodies – drainage water inlets from irrigated lands are defined, consisting in a comprehensive assessment of all components of the agro-landscape with the subsequent development of engineering, agrotechnical, agroforestry and agrochemical measures that contribute to the formation of a favorable environmental situation in the river basin.
