Numerical model was used to assess ice passage through proposed reservoir on the lower Vistula River. Model results were compared with observation on the Vistula River, but because the dam is not constructed yet, the direct comparison was not possible. The study focused on ice movement and accumulation in the reservoir for variety of low flow condition with and without wind effect. Bridge’s piers in the upper part of the reservoir were found to be one of the most important parameters affecting ice passage at the proposed dam. The other parameter which hampers or may even lead to stopping ice movement is western wind. The study took place within the framework of exclusive analysis for selecting the final location of a new dam which is critical for ensuring permanent safety of the Włocławek dam. Based on the performed study, the Przypust and Siarzewo variants accomplished the required goals to the largest extent at acceptable risk of ice stoppage and accumulation. Icebreaker operation is required during the ice sluicing operation in the new reservoir.
