The paper presents the influence of Suchedniów (V_NPP = 226,000 m³) and Rejów (V_NPP = 1,165,000 m³) water reservoirs, located in Kamionka catchment above Skarżysko-Kamienna, on the reduction of flood wave with a maximum flow intensity equals 50.40 m³ · s^-1. Analyzed flow hydrograph was obtained from measurements and observations conducted by the service of the Suchedniów reservoir from 26^thAugust to 6^th September 2010. Carried out the multi-variant analysis shows little effect the Suchedniów reservoir on the transformation of the flood wave at the current operating condition. In the case of Rejów reservoir, at the normal storage level, it is possible to reduce flood peak about 11.40 m³ · s^–1. Further increasing the efficiency of the reservoir, and thus safe running analyzed flood wave trough the town area Skarżysko-Kamienna needs to increase its flood control storage capacity.
