The hydrograph from a 5-hour storm measured at the outlet of a seasonal creek is shown below. The average concentration of lead in the runoff is assumed to be 40 mg/L based on previous sampling. What is most nearly the total mass of lead (in pounds, lb) that the creek contributed to the downstream water body during the storm? (Assume zero base flow).
