What is a Watershed?
What is a Watershed? Source: NOAA A watershed is where "Land that channels rainfall and snowmelt to creeks, streams and rivers and eventually to outflow points such as reservoirs, bays and the ocean" (NOAA, 2021). Water hits the ground from rain or snow and soaks into the soil. It then slowly moves into streams and rivers. Some of the water goes deeper while others avoid being infiltrated deeper into the soil. This means it will flows straight over the ground. When the ground is extremely hard, like clay soil, the water will flow straight across ground and take the "fast lane" straight into a river (NOAA, 2021). Along with the water that flows in or over the ground, pollutants flow into the river and streams. This leaves larger bodies of water open to issues from these pollutants and sediment flows. Watersheds generally flow from the highest points to the lowest points and then into rivers and then larger bodies of water (such as in the map below of the Little Calum...
