Chiangchun, Yensuei and Erhjen are three rivers in southern Taiwan. These rivers share the same characteristics as having relatively low stream flows and highly developed watersheds. Due to significant waste discharge from domestic, industrial and swine farming sectors, these rivers are heavily polluted. Anoxic conditions persist in most part of the river reach. A number of watershed management plans have been proposed in the past decade. However, the efforts were inefficient due to the lack of coordination between responsible agencies. In this project, alternative plans have been proposed. The short-term goal for stream water quality improvement is set on the elimination of anoxic conditions for all river reaches. Long-term goals are set for the three river to be in compliance with water quality standards. Plans for financial and technical support, as well as law enforcement strategies for industrial and farming sectors, and the requirements for sewer construction and sewage interception and treatment have also been proposed. Strong emphasis has been put on inter-agency coordination between institutions such as the Environmental Protection Agency, the Council of Agriculture, and the Construction and Planning Administration.
