Lakes and reservoirs play a critical role in the environmental and economic security of a population, providing water for food production, hydropower generation, navigation, and municipal use. Further, the sharing of transboundary waters requires international coordination in order to avoid conflicts between upstream and downstream neighbors. In this poster, I describe the development of a remote sensing-based system for continental-scale, near real-time monitoring of medium and large lakes and reservoirs. Time series analysis of NASA’s MODIS (Moderate Resolution Imaging Spectroradiometer) sensor drives this system, allowing long-term and near weekly updates of changes in lake and reservoir surface area. Leveraging the global, high frequency of MODIS observations will facilitate alerts of rapid changes in water resources, which can spark internal or international conflict.
