We describe the ongoing deployment of a wireless network system for monitoring aquaculture applications and managing a lake resource in one of the Seven Lakes in San Pablo, Laguna, Philippines. Field servers are deployed to measure water quality parameters such as dissolved oxygen and temperature. In addition, a novel floating platform field server is developed to gather data in the middle parts of the lake. Cameras are also deployed to monitor different aspects of the area. A knowledge management system allows dissemination of these data and other information that would be of interest to stakeholders and the local community
