It has been found that the low discharge in 2007 resulted from the extremely temperate winter and from the anomalous distribution of the precipitation events throughout the year. These factors, together with higher pH values of stream water in 2007, reduced the output of elements from the catchment. The output of dissolved Al, Be, Cd, Mn, Ni, Pb, and Zn through the stream water in 2007 is amounted to only 15 to 20% of their annual output in 1995–2006. The unusually low output of the elements distinctly affected their budgets in the catchment changing towards more positive mass balance values.
