It's very simple actually. All they did was make bags out of anything they had. For example, animal skins, minerals, rocks, food, and/or plants. They then filled the "bags" up with dirt or sand. Next, they tied the end of the bag with rope. After that, they made the same bags over and over. Finally, They stacks those bags up and form a dam. :D
P.S. It's funny. Some people now, do the same thing, execpt they use plastic bags and fill them up with sand! ;D
