		<abstract>The goal of the present work was to identify spectral features related to different densities of the phytoplankton species Ceratium furcoides. In an additional matter, band ratios were tested to identify the best relationship to the density of these organisms in reservoirs of the high stream on the Jacuí River in the State of Rio Grande do Sul. The samples were collected in three field campaigns in the reservoirs of Ernestina, Passo Real and Itauba. The effects of the density of individuals of Ceratium furcoides for every milimeter in the reflectance spectra were analised. The sampling consisted of 14 collection stations distributed along the reservoirs. The results showed that the shape of the spectra, with a peak of reflectance around 710nm, is associated to higher densities of the aforementioned organisms. In addition, it was noted that there was a shift of the peak of maximum reflectance in the visible spectrum to this wavelength in conditions of high concentrations of this organism. The maximum reflectance in the green band shifted to higher wavelengths as the density of individuals decreased and its magnitude decreased due to the higher density of individuals, with a less steep  reflectance peak. The ratio of bands, taking into account near infrared and red, was related to the density of organisms for every milimeter.</abstract>
