Abstract: The paper presents a brief overview of recent lake and reservoir restoration project activities in Taiwan, an island nation in a sub-tropical and relatively wet climate. Because of steep slopes and short lengths, rivers in Taiwan flow quite fast in their upper and middle reaches. Rain water reaches the sea in a rapid manner. Because of intense development and lack of wastewater treatment, many rivers are seriously polluted in their lower reaches. Therefore reservoirs are the main sources of water supply in Taiwan. In recent years, however, many reservoirs have been found to have water quality problems. To restore the water quality of these reservoirs, a number of activities have been undertaken including 1) artificial reaeration; 2) nonpoint pollution control, and 3) watershed management. These activities are described in this paper.
