Evaporation is one of the most significant losses from water levels, especially in desert areas. Because a large amount of water is stored in reservoirs, water losses evaporate from the surface of water reservoirs, which is one of the sources of water loss. So far, various solutions have been proposed to reduce the rate of evaporation. In the present study, which was conducted with the aim of reducing the rate of evaporation from Class A evaporation pans, it was attempted to investigate for the first time the efficiency of three types of balls as evaporation reducing coatings. The balls used, including three types of two-hole and six-hole balls and without holes with a diameter of 7 cm, made of propylene were used. In order to evaluate the performance of these coatings in reducing the evaporation of Class A pans for 2 months from 1400/6/1 to 1400/7/30. Based on the Tukey and Duncan mean test, the three ball samples had a significant difference of 5% in terms of changes in evaporation rate and temperature with the control. The results showed that holes without holes with 70.6% efficiency had the largest share in reducing evaporation, while two-hole and six-hole balls with 45 and 30% efficiency were in the next priorities. Finally, holes without apertures were identified as
