The study to determine thermal-oxygen changes and chemical properties of water in a flow-through pond was conducted between April 2004 and March 2005 in three vertical profiles. The study involved the determination of electrolytic conductivity and pH reaction of water as well as the content of nitrate nitrogen and ammonium nitrogen, total phosphorus and sulphates. Thermal stratification was not observed in the investigated pond with the maximum depth of 2.45 m, and oxygen content was represented by a clinograde curve. Biogenic element concentrations in the pond were determined by depth in the vertical profile, and they were subject to seasonal variation. The highest concentrations of mineral substances in water were reported in the bottom layers of the pond. Although the investigated pond is a flow-through water body, it accumulates biogenic elements.
