What is the lowest spot that water flows?

The lowest spot that water flows is typically known as a river's mouth, where it meets a larger body of water like an ocean, sea, or lake. In terms of elevation, the lowest point on Earth's surface is the Challenger Deep in the Mariana Trench, where water accumulates at depths of approximately 10,994 meters (36,070 feet). However, in terms of freshwater systems, the lowest points in rivers and lakes are where the water drains out, often influenced by topography and gravitational pull.
