The Rasina River Basin is located on the territory of Central Serbia. The aim of this paper is to determine the amount and spatial distribution of water resources, that is, to establish the participation of altitudinal zones in the formation of the total runoff in the Rasina River Basin area upstream from the "Ćelije" reservoir. In terms of methodology, determination of water volume is based on four separated petrological-hydrological complexes. Average weighted specific runoff in a given territory is 9 l/s/km2. Metamorphites and magmatites are in the first place per participation in the total water runoff of 42.8 %. The second place belongs to sedimentary rocks that make 39.6 % of the total runoff . Unbound sediments participate in the total runoff value with 10.5 % and limestone with 7.1%.

During 2010, 62065.3 t of the dissolved load were transported from the Crnica Basin, which was 5.1 times higher than the long-term average value. In hydrological terms the studied year was specific. In the period from January to May the amount of runoff water was significantly above the average perennial values, while in the period from August to November the amount was below the perennial average. According to the hydrological conditions in the period January-May 82.3% were transported, and in the period August-November only 5.1% of the annual dissolved load amount. Most of the year (54.2% of the time) the specific runoff was less than 10 l/s/km2, the average water mineralization was 374.9 mg/l, and in that time 13% of the total annual amount of the dissolved load was evacuated. On the other hand, the specific runoffs greater than 50 l/s/km2 represented 13.4% of the annual frequency, the average water mineralization was 263.3 mg/l, but for that time period even 53.9% of the annual quantity of the dissolved load was evacuated.
