A wastewater lagoon has a surface area of 350 x 10 m2. Average annual rainfall and evaporation are 1850.4 mm and1 142.7 mm, respectively. If the increase in storage is 247.8 x 10 m /year, determine the net annual inflow (losses) into (from) the lagoon. Give final answer in mm/year. What hydrologic components are included in the net inflow or loss?
