Precipitation runoff from lakes and streams all converge at a river or watershed outlet, where water flows into larger bodies of water such as rivers, seas, or oceans. This convergence is essential for maintaining the hydrological cycle, as it facilitates the movement of water from land to larger water systems. Additionally, these areas often support diverse ecosystems and play a critical role in the surrounding environment.

A runoff is precipitatoin soaks into the ground, precipitation can also run over the ground and flow into streams, rivers, lakes, and eventually the ocean.
The water that flows in streams and rivers into the ocean and lakes is called runoff or freshwater.
Approximately 38% of global precipitation that falls on land becomes runoff, eventually flowing into streams, rivers, and lakes. The remaining percentage is absorbed by the soil, evaporates, or is taken up by vegetation.
On average, about 21% of all precipitation becomes runoff into streams, rivers, and lakes, while around 79% infiltrates the ground to become groundwater. These ratios can vary depending on factors such as soil composition, land cover, and climate conditions.
Surface runoff occurs when precipitation or water from melting snow or ice flows over the ground surface. This water can accumulate in rivers, streams, ponds, or lakes. Factors that influence surface runoff include the slope of the land, soil type, vegetation cover, and the intensity of the rainfall.
Surface runoff that cannot penetrate the ground forms streams, rivers, or lakes.
