The paper presents the results of investigations on changes of heavy metal contain within the deposits of the check dam water reservoir situated on the mountainous stream along the long term observations done between 1977-1981 and in 2002). The work was realized in the Kasinka Stream watershed in the Beskid Wyspowy in Polish Carpathians. The catchment area of the Kasinka Stream is 49,6 km2, the length of the Kasinka to the research cross section is 16,2 km, the precipitation is 914 mm, and the t-years floods within the check-dam cross section are as follows: Q10% = 32,0 m3 s-1, Q5% = 40 m3 s-1, Q2% = 52 m3 s-1, Q1% = 63 m3 s-1, Q0,5% = 73 m3 s-1 and Q0,1% = 99 m3 s-1. The Kasinka Stream is the 3rd order tributary of the Raba River which is the 2nd order tributary of the Vistula River. The Kasinka watershed is situated within the recreation areas of Krakow (the Raba Valley and Mszana municipality). The area is quite dense populated with many tourist areas. Also it is here where the road to Zakopane is nearby. All ...
