State watershed and drainage basins precisely and explain why it matters in 2-3 sentences.

# Watershed and Drainage Basin Definition A **watershed** (or **drainage basin**) is a land area where all precipitation and surface water drains downhill to a common outlet point, such as a river mouth, lake, or ocean, bounded by elevated ridges called divides. ## Why It Matters Watersheds matter because activities anywhere within the basin—like pollution, deforestation, or urban development—affect water quality and quantity downstream for all communities and ecosystems sharing that water system. Understanding watershed boundaries is essential for effective water resource management, flood control, and protecting drinking water supplies for millions of people who depend on the same connected water source.
