Considering the advantage of the Canadian council of ministers of the environment water quality index (CCME-WQI), this study evaluated the rivers and lakes water quality in the Taihu Lake Basin from 2013 to 2017. This study aimed to devise an efficient approach for water quality assessment, providing a scientific and straightforward management tool for watershed agencies in China. Results showed that BOD5, CODCr, CODMn, and phosphorus were widespread and persistent pollution sources within the Taihu Lake Basin during the study period. Additionally, ammonia-nitrogen nutrients emerged as a potentially contributorto pollution, while heavy metals were identified as episodic pollutants. Based on the CCME-WQI scoring system, indicated “moderate” water quality for the basin. Spatial heterogeneity was observed in water quality, with “good” water quality around the South River systems and the Camps Creek. Temporal variation of water qualitywas also observed, the CCME-WQI values increases continuously over the study period. Seasonally, the highest CCME-WQI values was observed in autumn, followed by summer and winter, with the spring lowest. This study accurately evaluated the water quality of the Taihu Lake Basin using CCME-WQI method, providing a suitable and reliable tool for water quality evaluation in China.
