KiwiMill built a newer version of this model. Take a look here: Hydroelectric Dam Working Model

This is a working model of a hydroelectric dam.

The working model was created for the government to demonstrate the properties of hydroelectric power. Water is channeled through the working model, mimicking the real life dam.

The working model was built to illustrate 4 concepts; The spillway, bypass, river flow and electric generator.

This video shows the dam model in action:
