Monthly water temperature data were taken for La Cuarentena pond and Paraná River, Argentina, over a two-year period. The data show that the pond is seasonally unstratified and that any stratifications are occasional and slight. However, strong stratifications were observed under floating macrophytes. The thermal regime is principally influenced by the basin morphology, air temperature, wind and floodwater. As a result of its temperature and circulation pattern, La Cuarentena pond can be classified as "continuous warm polymictic". The heat budget is about 3,000 cal/cm2, with maximum heat content of 5,000 cal/cm2. The heat budget for bottom sediments is about 1,100 cal/cm2.
