Abstract Lake Batur is one of The National Priority Lakes according to President Regulation Number 60/2021 with the target of restoring water quality through the pollution control program for floating net fishery (FNF), agriculture, and other anthropogenic sources around the watershed. The regulation also states several internal measures designed to restore the lake’s water quality. Unfortunately, detailed information on pollution control priorities, the amount that must be controlled for water quality improvements to be visible, and the effectiveness of internal restoration efforts have yet to be obtained. This can hinder the lake restoration process and, furthermore, its sustainable management. This study aimed to develop a web-based numerical model as an open-source web-service for guiding restoration in Lake Batur. It is accessible via the interactive graphical user interface (GUI) running in a standard web browser and includes tools of varying complexity. The platform provides the user with features to set up some parameters, run and analyze the numerical water quality, and the possibility to set up, run and compare various lake management scenarios. The preliminary results show that the model was able to represent existing daily water quality dynamics. Hopefully, the model can be used as a tool for lake restoration and as a part of sustainable lake management.
