DOI : 10.17693/yunusae.v16i26717.281029 Viewed : 1899 - Downloaded : 1221 Samples were taken from Cip Dam in winter, spring, summer and autumn seasons of the year 2011 for determining the seasonal changes in littoral sediment`s phosphorus level. Sediment and episediment water samples were taken from determined station, and then some physical and chemical analysis were performed firstly on the phosphorus and its fractions. In this study, TFF concentrations of sediment pore water varied between 32-82 μg L-1 and TFO between 20,60-32,35 μg L-1; these values showed that the lake has eutrophic characteristics. The ratio of TFO concentration to the episediment water (approximately1.5-2 times) could not be seen in high enough to stimulate phosphorus oscillations. In Cip Dam TFE/TFO values of sediment pore water varied between 0.13-0.19, and these results were put in no inhibition of phosphorus oscillation has been occurred. TFF values of episediment of Cip Dam Lake were showed parallel seasonal differences with TFF values of sediment, and were found to be 1.5 - 2 times higher than the values in literature. This would seem that this status has got a low effect on sediment phosphorus oscillation In Cip Dam phosphorus values of lake water were determined to be 50,08-83,24 µg P L-1 and according to releated literatere (indices) the trophic status of the lake could be evaluated as mesotrophic and eutrophic. To protect the lake nutrient level first of all allocthonus phosphorus entrances had to be reduced and taken under control. Keywords : Cip Dam,phosphorus,pore water,sediment
