             abstract = "Scientific researches focused on the water quality use, in 
                         general, empirical models of inference on water components from 
                         others observed in field, allowing a better spatial representation 
                         of the variable, beyond reduction of costs. Environmental 
                         researchers use the Secchi depth in indirect calculation of 
                         vertical attenuation coefficient for water irradiance and in the 
                         estimation of stretching euphotic zone to classify water types on 
                         Brazilian water ecosystems. Then, the main aim of this research 
                         was to realize the inference of water euphotic zone and the 
                         vertical attenuation coefficient for water irradiance in UHE 
                         Mau{\'a}/PR Reservoir, using the Landsat-8/OLI multispectral 
                         image, in spectral bands 1 (450-510 nm); 2 (530-590 nm); 3 
                         (640-690 nm); 4 (850-880 nm) and 5 (1570-1650 nm) and spectral 
                         data collected in situ, and to generate an inference model of 
                         water transparence through available data. After adjustments and 
                         initial processing, the data were submitted to a correlation 
                         analysis, where there were found significant correlations 5% 
                         confidence level, not being raised the inference model. The data 
                         collected in situ sampling points, made it possible to estimate 
                         the vertical light attenuation coefficient in the water of the 
                         reservoir; classifying water as eutrophic; and estimate the depth 
                         of the photic zone, too narrow (between 2,29 m and 2,97 m). So 
                         concluded that the reservoir presents not much concentration of 
                         suspended solids and are in eutrophication.",
