 With Vensim system simulator, a stock and flow diagram was created as illustrated. The simulation model is simply based on Reservoir Volumes as Stock Variables, which have feed mechanisms with flows and attributes, and also Reservoir Volumes are feeding each other as interconnected with flows to each other.

 Which basically explains The Company PMP should not invest in constructing a second (Downstream) reservoir as large as the first (Upstream reservoir). Pumped up water volume can trigger discharge of water in the first reservoir if both reservoirs have equivalent capacities, which can cause loss of generation in the long run and therefore loss of revenues.
