This study was conducted from January 2014 to October 2015 to find out accumulation of heavy metals in fishes and water of Changhoz dam Karak, K.P.K. Pakistan. For this purpose three samples of fishes namely Hypophthalmichthys molitrix (silver fish), Crossocheilus latius (Dogra) and Hypophthalmichthys nobilis (Bighead) from different sides and four samples of water from left/north, right/south, front and outer coming region of changhoz dam were collected during the months of February and March 2015. Heavy metals for which these samples were analyzed were Cadmium, Zinc, Iron, Copper, Nickel and Lead. In Hypophthalmichthys nobilis (bighead) highest concentration is showed by Iron in region of Scales while Cd and Ni were not detected in any part, other element detected with concentration comparably less to Permissible limit. In Hypophthalmichthys molitrix (Silver fish) highest concentration showed by Ni in Abdomen while in other parts Ni along with Cd were not detected, Fe and Pb showed normal range while Zn and Cu showed less concentration than permissible rang. In Crossocheilus latius (Dogra) highest concentration showed by Pb in scales, Cd not detected in any part while Fe and Zn showed concentration in rang of permissible limit. In water of four side Zn, Cd and Ni showed less concentration other nearly same with permissible limit.
