The researchers estimated the maximum allowable pollutant load for phosphorus and nitrogen in Taihu Lake for 2015 and 2020. They calculated the minimum pollutant reduction needed to meet water quality targets and developed detailed discharge limits for different areas. It is possible to achieve strict water quality goals with significant pollution control efforts. After 2020, the lake's water quality may remain at certain levels due to the risk of algal blooms. To improve water quality in the long term, suggestions include transferring water from the Yangtze River and clearing algae from the lake.
