The Seven Lakes of San Pablo, Laguna, known for their diverse ecosystem services, including ecotourism, aquaculture and cultural significance were recently assessed for their water quality. The water quality assessment revealed notable variations among the lakes during different months, including the presence of various types of algae both beneficial and harmful to living organisms in the lakes. This was done through the project, “Development of Models for the Assessment and Monitoring of the Seven Lakes of San Pablo,” implemented by the University of the Philippines Los Baños (UPLB) and led by John Vincent R. Pleto.
