		<abstract>Limnological variables along with inherent optical properties provide substantial information about aquatic systems and are crucial in development of bio-optical models. In the present work we measured the inherent optical properties of a tropical Brazilian reservoir (Três Marias) simultaneously to the concentration of optically active constituents such as chlorophyll-a, total suspended solids and dissolved carbon in order to characterize its bio-optical behavior. From June 17th to 22th 2013 twenty-two sampling stations were profiled using a 25cm pathlength AC-S attenuation-absorption meter (WET Labs) and a Hydroscat-6 backscattering meter (HOBILABS). Data set revealed a division of reservoirs water body in two main water masses with distinct biological and optical properties. Optically active constituent concentration varied irregularly across the reservoir, reaching 1.69-13.22 µgL^(-1) for chlorophyll-a, 1.6-11.93 mgL^(-1) for total suspended sediments, 7.35-8.9 mgL^(-1) for dissolved total carbon and 0.18-0.64&#12310; m&#12311;^(-1) for CDOM absorption in 443nm. Relationship between chlorophyll-a concentration and the other constituents were low: 0.001 for total suspended solids and 0.26 for total dissolved carbon. Chlorophyll-a concentration showed a strong correlation with total absorption in visible range with determination coefficient between 0.63 and 0.95. Phytoplankton was the dominant constituent in the reservoir (followed by CDOM) and controlled the heterogeneity observed in IOPs during sampling time.</abstract>
