The paper presents the results of the research of nutrients concentration (total nitrogen - TN, NH4, NO3, NO2, total phosphorus - TP, PO4) in the waters of inactive quarries. The aim of research was to assess the condition of quarry lakes. Average concentration of TN was within 1.10-3.50 mgNdm-3and TP in the range of 0.39-1.08 mgP/dm3. No risk of reservoir enrichment by nitrates from agricultural sources was found, the maximum NO3 concentration was 1.06 mgNO3/dm/-3. High concentration of TP (>0,1 mgP/dm3) causes eutrophication, occurring in all reservoirs, manifested by algal blooms and affects poor water status assessment. The worst water quality was found in the quarry lakes KG-3 and KG-2 exposed to the sewage from farms. The examined indicators of water pollution in quarry lakes KG-1, KŁ-4, KM-5 fulfill the requirements of category A1 and potentially may be a source of water for consumption (after water treatment)
