It is constructed by digging a trench the length of the dam. The trench is dug down through the top soil, rock, sand or any material that would let water pass until a good clay soil layer is reached. The minimum depth of the core trench is a least 4 feet. Clay soil material is then packed back into the trench.

What is the best way to build a dam?
Streams and rivers have to be diverted to create a dry area to construct the dam. Small rivers and streams are usually diverted through a tunnel, or a channel that is constructed around the side of the dam. Soft soils and rocks are excavated to form the route, while harder rocks have to be blasted with explosives.

How electricity is produced in dams?
The dam stores lots of water behind it in the reservoir. Gravity causes it to fall through the penstock inside the dam. At the end of the penstock there is a turbine propellor, which is turned by the moving water. The shaft from the turbine goes up into the generator, which produces the power.
How many yards of dirt are in a 1 acre pond?
