As a result, our team has outlined a preliminary plan to incorporate chlorophyll-a levels alongside CTSI as a means to enhance the assessment of eutrophication status in domestic reservoirs in Taiwan. Additionally, we will be conducting a series of seminars on the 'Improvement Methods for Water Quality Management Indicators in Taiwan Reservoirs' in the northern, central, and southern regions of the country. These seminars will serve as platforms to gather input and insights from experts, scholars, environmental organizations, and other stakeholders. The collected feedback will be used as a reference for the Environmental Protection Administration in their future development of water quality management indicators for reservoirs.
