Below a discharge from wastewater treatment plant, an 8.6-km stream has a reoxygenation constant of 0.4/d, a velocity of 0.15 m/s, a dissolved oxygen concentration of 6 mg/L and an ultimate oxygen demand of 25 mg/L. The stream is at 15 °C. The deoxygenation constant is estimated at 0.25 /d. Will there be fish in this stream?
