Influence of the Stare Miasto reservoir on the Powa river water quality
Summary.

In the paper the influence of the Stare Miasto reservoir on water quality in the Powa river is presented. The analysis is done for hydrological years 2011-2012. For the purposes of the research, the water quality is compared in two measurement-control points (MCP) located upstream and downstream of the reservoir. The Stare Miasto reservoir is a small reservoir used for control and modify annual flow regime. The reservoir is located on the Powa river between km 9+100 and km 13+800. It is noticed that the amount of biological and chemical oxygen demands (BOD, COD) in the downstream MCP is higher than it is measured in upstream MCP. The differences are 87% and 23%, respectively. It is realised that a possible reason may be the inflow of sewage waters from a boarding house located 100 m from the main dam. In addition the positive influence of the reservoir on the amount of dissolved oxygen (DOX) was observed. The increase of concentration in downstream MCP is about 38%. The concentrations of orthophosphoric substances are decreased by about 68%.

Key words: water quality, physical and chemical indicators, reservoir
