Investigation of Some Water Quality Parameters of Derek？y Pond (Kilimli - Zonguldak)

Derek？y Lake is a pond, which was constructed to meet the water demand of the thermal power plant located in Zonguldak Province, Kilimli city, ？atala？z？ district. The average depth of the Derek？y Pond is 3,8m, and the surface area is 20 hectares. The area around the pond is surrounded by forest. It was aimed to determine the water quality characteristics of Derek？y Pond (Kilimli-Zonguldak) in this study. The study was started on March 2015 and water samples were collected from three different stations representing the whole pond monthly for 12 months.Dissolved oxygen (DO), salinity, pH, temperature, suspended solids (SS), chemical oxygen demand (COD), total hardness (TH), total ammonia nitrogen (NH4-N), nitrite and nitrate, as water quality parameters, analyzes were performed. As a result of the study; It is determined that the current water quality status of Derek？y Pond is in 1st and 2nd class water characteristics according to SKKY and it is determined that current water quality conditions are suitable for aquatic organisms life but it is under pressure of pollution
