Abstract:

In this study, on the coastal areas of Kalecik and Cip Dam Lake with similar size surface area, seasonal variation of water quality were evaluated in the two sampling points in April, June, October, December of 2011. The temperature, dissolved oxygen saturation, pH, conductivity, total hardness, total alkalinity, chemical oxygen demand, dissolved anions and cations (lithium, sodium, potassium, calcium, magnesium, ammonium, nitrite, nitrate, fluoride, chloride, bromide and sulfate ) and the total phosphorus amount were monitored. Kalecik Dam Lake was characterized as a medium hard waterly lake with lower pH and having low electrical conductivity and total solids amount, relatively low amounts of anions and cations were contained. Having higher pH, Cip Dam Lake was identified as a hard waterly lake which has high electrical conductivity and total solids amount as a result of dissolved anion and cation content. Each of the two reservoirs were determined as eutrophic lake at Class-II quality, due to the high total phosphorus content.
