Abstract This research study aims to study and compare the water quality in Ban Hat and Ban Nong Lung reservoirs, Phak Mai Subdistrict, Huai Thap Than District. Sisaket Province began the study between November - July 2025, which measured water quality in 4 parameters: temperature, pH value (pH), dissolved oxygen in the water (D0). The results of the study found that the temperature value was betweenThe temperature ranged from 28°C to 34°C, with a pH of 6.83 to 7.54 and dissolved oxygen (DO) of 6.0 to 7.5 mg/L. Comparing water quality across months and at the two sampling points, it was found that all water quality parameters differed significantly during May-July. The differences were as follows: Ban Hat Reservoir had a temperature of 32.5°C, a DO of 7.5, a pH of 7.54, and a water transparency of 14, while Ban Nong Lung Reservoir had a temperature of 33.8°C, a DO of 6.0, a pH of 6.83, and a water transparency of 23. This indicates that Ban Nong Lung Reservoir is cleaner than Ban Hat Reservoir.
