Basic characteristics of the construction and its future operation:
Water work Slatinka is an accumulation reservoir in the river basin of Hron, on the river Slatina, above Zvolen. Its main purpose it is designed for is to augment the river flow of Hron (accumulation of water during higher flows and discharge of the flow during droughts) so that in every period of the year sufficient amount of water in the river is provided for all customers, while providing a sufficient minimum balance in Hron below Veľké Kozmálovce
WW Slatinka will have some more significant effects: lowering flood flows on Slatina in Zvolen and on Hron below Zvolen, generation of electricity in small hydropower plant and recreational contribution of the reservoir for wide surroundings.
