Due to the non-uniformly distributed precipitation and the steep-sloped rivers, reservoirs have been widely built to manage the water supplies in Taiwan. However, the eutrophication problem that results from the inappropriate managements from upstream watershed is prevailing in most reservoirs. The FeiTsui reservoir has been providing raw water for the Great Taipei Metropolitan area, and its water quality has been well protected by associated authorities. Nevertheless, recent monitoring data and researches suggest that the water quality has reached the near-eutrophic state, especially when Taipei-Ilan expressway was constructed and came to operate.
