The paper presents the effects of the dam reservoir in Komorów on the water quality in the Utrata river. The implementation of the adopted objective involved a comparison of water quality at two points, above and below the reservoir. The Utrata River is polluted with biogenic compounds throughout the whole section studied. COD content also indicates significant contamination exceeding permissible limits. A positive effect of the reservoir on water quality in the river was also observed in terms of the content of dissolved oxygen, with concentration increasing below the reservoir. The reservoir had a positive effect on reducing the concentration of total phosphorus in the water. Water in the Utrata below the reservoir showed higher values of chemical oxygen demand (COD) than above the reservoir. There were no differences in the concentration of NH and NO ions in the water before and after the reservoir.
本文介绍了科莫罗夫大坝水库对乌特鲁塔河水质的影响。为了实现既定目标，在水库上下游两个点对水质进行了比较。乌特鲁塔河整条河流都受到生物化合物的污染，研究表明其化学需氧量（COD）严重超标。研究还表明，水库的存在对河流下游水中溶解氧的含量有积极影响，其浓度在水库下游有所增加。水库的存在对降低水中总磷浓度也有积极作用。与水库以上的水相比，乌特鲁塔河下游水中的化学需氧量（COD）浓度更高。水库前后水中氨（NH）和硝酸盐（NO）离子的浓度没有差异。
