In support of LLDA’s mandate and various programs, the Decision Support System (DSS) and Water Quality Monitoring (WQM) Program are implemented to aid in monitoring and relevant policy decision-making.
The DSS, introduced by the Royal Government of the Netherlands through a funding for the Sustainable Development of Laguna de Bay Environment (SDLBE) Project in 2000, integrates state-of-the-art software tools to provide an adequate scientific description of the Laguna de Bay water system (catchment and lake).
As part of WQM, lake and river water quality are monitored continuously through thirty six (36) stations located in the rivers of Marikina, Bagumbayan, Mangangati, Tunasan, San Pedro, Biñan, Sta. Rosa, Cabuyao, San Cristobal, San Juan, Los Baños, Bay, Pila, Sta. Cruz, Pagsanjan, Pangil, Siniloan, Sta. Maria, Jala-jala, Pililla, Tanay, Baras, Taytay Barkadahan and Morong, and also in Sapang Baho and the Buli Creek.
