Abstract

In the last decade, hydrological and limnological studies were conducted in a black-water lake aiming to develop a model of water circulation to meromictic lakes from Negro River basin at the Brazilian Central Amazonian. Parameters as temperature, euphotic zone (Zeu), attenuation coefficient (K), density, oxygen and morphometry were measured daily. Zeuand K proved somewhat constant throughout the hydrological year. In the low waters periods were observed a theoretical mean residence time of water of about 150 days. The meromixis condition was observed with continuous physical and chemical stratification in all hydrological cycle, showing a hypolimnion very defined. The thermal stability was explained by the distinction densities between upper and lower strata, with bottom water flux from forest-rivers. The morphometry of the lake and presence of a flooded forest surrounding, were important factors in reducing wind action on the water column, reducing the effect of stimulating the circulation and stratification process.
