Abstract: The purpose of establishing and implementing TMDL is to indentify the specific pollution control unit and the land use status，to propose some control measures about concentration and total amount for point source and non-point source pollutants emissions，within the unit which are necessary to facilitate the implementation of best watershed management and pollution control plan at the whole basin，to meet the water-quality target management requirements． Taking the Navarro river as an example，through the analysis of the TMDLs for temperature，and combined with the water-quality target management technology in our country，the suggestions and methods of the basin temperature load distribution were put forward． Some references were provide for our country water environment management about river temperature in the future．
