The depth is basic and important parameter for lake water resource management. In Southeast Asian countries where are attacked by typhoon and flood every year and face to water pollution risks by rapid urbanization, it is urgent issue to construct water level monitoring system for lakes and rivers. On the other hand, there are two issues for updating the information regularly, budget constraint and accessibility constraint. In this research, we developed the simple depth measurement method using fish finder and apply to create bathymetric map on LAGUNA Lake, Philippines. It identified that the method is efficient to improve those issues and available to aggregate depth data more effectively for contributing water resource management policy and the evaluation.
