Why is knowing your watershed important? Well, watersheds contain all the water bodies that supply our drinking water, water for agriculture and manufacturing, offer opportunities for recreation like kayaking and swimming, and provide habitat to plants and wildlife.
Rain and snow fall to earth (precipitation) some of it evaporates, some soak into the soil, and some fills lakes and rivers, eventually flowing into the ocean.

Save our One World Ocean
Overland flow or runoff water can be seen on the street flowing into a street drain.
Any litter or invisible toxins on the ground are picked up by the runoff water and carried to a street drain or underground into urban streams, rivers, lakes, and the ocean.
