                         trophic state of reservoir water. Daily average of Chlorophyll 
                         (Chl) concentration from February, 2007 to February, 2008 was 
                         obtained with automatic monitoring systems moored at FUNIL 
                         reservoir. The data were processed to identify phytoplankton 
                         blooms which were defined by Chl concentration > 20mgl-1 and 
                         duration > 2 days. The dates of bloom were then used to select 
                         satellite images available during the episodes As revious results 
                         in cascade systems reservoirs indicated a good correlation between 
                         the Normalized Difference Vegetation Index (NDVI) and chlorophyll 
                         concentration, it as hypothesized that under eutrophic conditions 
                         the NDVI would be positive due to the high cell density near the 
                         surface. The selected image was processed to derive the NDVI for 
                         the reservoir and compared with chlorophyll concentration provided 
                         by the automatic system. The results showed that the NDVI is 
                         sensitive to changes in chlorophyll concentration in eutrophic 
                         systems as FUNIL reservoir and can be used for quick assessment of 
                         the area affected by nuisance blooms. Although preliminary, the 
                         results show the potential of integrating automatic collected in 
                         situ data and satellite images for assessment of aquatic system 
                         trophic state.",
