What is a sub catchment stream?

A sub-catchment stream is a smaller water body that drains a specific area, contributing to a larger watershed or catchment. It collects runoff from rainfall, snowmelt, and other sources, channeling this water into larger rivers or lakes. These streams play a crucial role in the hydrological cycle, supporting local ecosystems and influencing water quality within the larger catchment area. Understanding sub-catchment streams is essential for effective water management and conservation efforts.
