The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.
Beavers build a lodge. This is entered from under water but is above water level inside. A dam is built to control the water level.
One time a Dam man went to drink the Dam water. He was all out of Dam water so he went and got his Dam bucket to fill it up with Dam water from the Dam well. His Dam well was empty, so he went to another Dam man to get Dam water. He asked the Dam man," Can I have some Dam water, Please?" The Dam man Replied, "Get your own Dam water!"
Yes. The height of the water level above the turbine affects the water pressure, and therefore the amount of power that can be generated.
