The present study was carried out with the aim to assess of water quality using physico-chemical parameters of Çamlıgöze Dam Lake located at Central Anatolian region of Turkey. For this purpose, water samples were collected from surface and 10 m depth from two stations selected in Çamlıgöze Dam Lake. The physico-chemical parameters such as water temperature, pH, dissolved oxygen, oxygen saturation, conductivity, salinity, secchi disc depth, nitrate, nitrite, orto-phosphate, sulfate, chloride, total hardness, calcium and magnesium were analyzed in the water samples. By assessing the physico-chemical data according to the Turkish water pollution control regulation, the water quality classes of the chosen stations in Çamlıgöze Dam Lake were determined as class-I in respect to the pH, dissolved oxygen, oxygen saturation, nitrate, nitrite, sulfate and chloride. Water temperature, conductivity, salinity and orto-phosphate of Çamlıgöze Dam Lake were within desirable limits. Çamlıgöze Dam Lake could be classified as moderately hard in terms of total hardness. It was categorized as mesotrophic by secchi disc depth. Based on the values of the obtained physico-chemical parameters, it can be concluded that the Çamlıgöze Dam Lake water quality was good and did not show any significant pollution problem. The results obtained from the present study shall be useful in future management of the Çamlıgöze Dam Lake.

The concentrations of heavy metals (Ag, Cd, Co, Cu, Ni, Pb, Zn) were analyzed in muscle, skin and liver of Anatolian Khramulya, Capoeta tinca (Heckel, 1843) from Çamlıgöze Dam Lake located at Central Anatolian region of Turkey. The heavy metal analysis of samples was carried out by using a flame atomic absorption spectrophotometer. Ag, Cd, Co, Pb and Zn were found in all of the examined tissues. Cu and Ni were not determined in all tissues studied. The mean concentrations of heavy metals in all of the examined tissues of Capoeta tinca were as follows: Ag: 0.057 ± 0.038–0.120 ± 0.051, Cd: 0.020 ± 0.004–1.451 ± 0.879, Co: 0.127 ± 0.067–0.205 ± 0.086, Pb: 1.939 ± 0.477–2.604 ± 0.393 and Zn: 0.056 ± 0.014–0.530 ± 0.129 μg/g in Çamlıgöze Dam Lake. According to international criterias and Turkish regulation, heavy metal concentrations especially Cd and Pb in Çamlıgöze Dam Lake were found above the permissible levels for examined tissues of Capoeta tinca. Furthermore, frequent consumption of contaminated fish is able to offer a serious public health risk. Therefore, the concentrations of metals accumulated in the fish, which are commonly consumed by public, should be monitored periodically in Çamlıgöze Dam Lake.

In this study, condition factors were determined for seven Cyprinid fish species from Çamligöze dam lake located at central Anatolian region of Turkey. The obtained results were compared with other studies from different habitats in Turkey. Fish samples were collected seasonally with nets of various mesh sizes from April 2010 to January 2011. Cyprinus carpio (1.6362 ± 0.2785) was determined to have the greatest mean condition factor followed by Capoeta tinca (1.3126 ± 0.1927), Leuciscus cephalus (1.2915 ± 0.3021), Barbus plebejus (1.1142 ± 0.1973), Chalcalburnus chalcoides (1.1138 ± 0.1251), Capoeta sieboldii (1.0214 ±0.1547) and Chondrostoma nasus (0.9894 ± 0.2281) in Çamligöze dam lake. For Çamligöze dam lake, condition factors of Cyprinid fish species are given for the first time. Condition factors of seven Cyprinid fish species around "1" showed a good level of nutrition of fish and nutritional capacity in Çamligöze dam lake.
