I am curious why the water doesn't just leak into the ground? I build a pond in my back yard and when a branch falls from the trees above penetrating the lining, the water leaks into the ground and empties my pond. Yet people built a dam a century ago and the water happily collects into a reservoir. Can anyone explain the geology of this?
