Abstract
Tseng-Wen Reservoir is the largest reservoir in Taiwan. It is also the most important water resource of Taiwan's largest plain - Chianan Plain. Due to the development of recreation and agriculture applications in the drainage area, the water quality was achieving a eutrophic state. The concentration average of the total nitrogen (TN) was 0.92 mg/L. The concentration average of the total phosphorus (TP) was 40 μg/L, and the concentration average of chlorophyll-a was 5.84 μg/L. The nutrient released to the reservoir primarily came from non-point pollution sources. Regardless of the forecast which occupied 77% of the drainage area, agriculture lands contributed 16.4% of the TN and 11.3% of the TP to this reservoir. Fishing also contributed 7.6% of the TP. Therefore, regulating inappropriate forest applications, promoting best management practices (BMP) in agricultures, and forbidding the fishing activities are recommended to improve the water quality in this reservoir.
