                         experienced one of the worst water supply crises in his history. 
                         The Cantareira System (CS), the largest water supply system of 
                         SPMR formed by 5 reservoirs, reached critical operational levels 
                         leading to supply problems. We presented an application of 
                         Landsat-8/OLI images to monitor the dynamics of water supply 
                         systems. Different techniques to delineate the reservoirs 
                         superficial area (RSA) were tested. Then, a multi-temporal 
                         approach was applied to monitor the RSA dynamics. The results 
                         showed that the Modified Normalized Difference Water Index (MNDWI) 
                         was the method which presented the best results to delineate the 
                         RSA. The multi-temporal approach showed that between May 2013 and 
                         August 2014 the CS RSA decreased 27 km˛ (~37%). The Jaguari was 
                         the reservoir of CS which presented the highest decrease in the 
                         RSA (~ 58%). The RSA showed a high correlation with the water 
                         volume in the CS (R˛ > 0.9). In a future step, the time series of 
                         RSA and auxiliary data will be used to generate a model to predict 
                         the CS volume dynamic.",
