This article presents the development of ice formation phenomena on Bistricioara River in the winter of 2011 – 2012, as compared to the winters 1962 – 1963 and 1963 – 1964, and the ice jam phenomenon in January 2014, on a river sector where there were no records of ice formation phenomena over the previous years, not even shore ice during the harshest winters. Moreover, the fact that down the river course there are records of some sectors, under identical climatic conditions, with well developed ice formations and quite close there are sector with poorly developed or even no ice formations proves that there are some other factors besides the meteorological land hydrological ones that could have a strong influence on the development of ice formations (e.g., the hydraulic relations developed between the river and the areas it crosses).
