falls onto the land (or melts from snow, sleet, or hail), it flows over and soaks into the land. The surface runoff and the water that soaks into the ground eventually flow into creeks, rivers or other waterbodies.
separate one watershed from another.
Water drains down the hills into
the streams in the valleys. The streams continue to flow downhill toward sea
travel downstream, streams merge into larger streams. The water shed of a larger stream consists of all the smaller watersheds, or subwatersheds.
that drains into the Indian Rill creek is in the Indian Rill watershed.
The parking lot and floodplain meadow
drain into Indian Rill as do the properties upstream of us all the way to Old Wilmington Road. The Indian
Rill Watershed and all of the other small watersheds
from the other small creeks all drain
into the Red Clay Creek. The Red Clay flows into the Christina River which is part of the Christina Watershed which is
part of the bigger Piedmont Watershed (the
watershed that includes the Red Clay,
White Clay, Brandywine, Naamans, and
Shellpot Creeks as well as the Christina).
address is similar to a postal address. Like your house is on a street, your yard is part of a small local creek watershed.
Your street is in a city similar to the way your local creek watershed is part of one of the
state’s subwatersheds. Your city is in a state like your subwatershed is in a State of Delaware Watershed. And your
state is within the United States like all the Delaware Watersheds are part of the Atlantic Ocean Watershed.
that whatever happens on the Ashland parking lot or floodplain meadow below the lot - or on our upstream
neighbors’ yards along Indian Rill all the
way up to Wilmington Road - can affect
Indian Rill, the Red Clay Creek, the portion of the Piedmont Basin downstream of us, the Delaware River downstream
of Wilmington, and ultimately the Atlantic
Ocean. The same is true for your yard and neighborhood.
