Moving millions of gallons of water across varied terrain without any electrical pumps requires insane geometrical precision. Engineers calculated a continuous drop of just a few inches per mile, maintaining a perfectly steady gradient through mountains and across massive valleys. If the slope was too steep, the water would erode the stone; too shallow, and the water stagnated. They nailed the math perfectly using primitive measuring sticks.
