How can you identify a place’s
watershed address?
 If there is a creek or river nearby that would be the
beginning of that place’s watershed address. If there is
a bigger creek or river or bay that it flows into, that will
be the second part. When you get as general as
possible, that is the end of the watershed address.

Groundwater
 Water that
exists beneath
the earth's
surface in
underground
streams and
aquifers
Lakes
 A body of water that is
usually fresh.
 Lake Drummond
 Smith Mountain Lake
 Lakes are considered
resources because they
provide sources of
food, water and
recreation.
Reservoirs
 an artificial or natural
lake where water is
collected as a water
supply
 Nearly all lakes in Virginia
are man-made reservoirs,
created by dams that block
streams and flood land to
form a lake.
Rivers
 a large stream that flows across land.
 What are Virginia’s
4 major rivers?
 James River
 York River
 Rappahannock
 Potomac
Bays
 an inlet of the sea or some
other body of water, usually
smaller than a gulf.
 The Chesapeake Bay is
Virginia’s largest water
resource.
 Bays are extensions of larger
bodies of water, such as lakes
or oceans. The Chesapeake
Bay is an extension of the
Atlantic Ocean and it is salt
water.

We all live Downstream….
 Everything we throw away or
dump down the drain affects us.
 The pollutants flow into the
watershed and into the rivers and
oceans.
We all live Downstream
(continued)…
 The polluted water then
evaporates and comes down as
rain which we drink.
 We need to take care of the
earth because humans and
animals need clean water.
