A fisheries biologist with the Iowa Department of Natural Resources says the dry conditions across the state are getting to a point where they could impact the state fish population. Jim Wahl says fish seek out deep water to survive during the winter.He says the smaller streams and rivers are hurt the worst by drought. Wahl works in the Clear Lake area which is at its lowest level in five years. He says fish in such lakes have a better chance of surviving in these dry conditions.Wahl says game fish would likely suffer the most if there were an early freeze in the smaller streams and rivers in the state. Some wells in southwest Iowa are reportedly drying out.
