Water supports all living things - humans, plants
wildlife.
3
Texas primary sources of water are groundwater
and surface water.
4
GroundwaterWater found underground
5
Nature stores groundwater in underground spaces
in rock formations called aquifers.

Texas Groundwater
96 of the groundwater we use comes from these
nine aquifers

• OGALLALA
• GULF COAST
• EDWARDS
• CARRIZO
• TRINITY
• EDWARDS-TRINITY
• SEYMOUR
• HUECO-MESILLA BOLSON
• CENOZOIC PECOS ALLUVIUM

Rainwater Recharges Aquifers

Aquifers feed streams, rivers, and wildlife
through springs.

Groundwater is the primary source for water for
irrigation in Texas.
10
Surface waterWater found on the surface of the
earth
11
Rivers, streams and lakes comprise Texas surface
water.
12
Surface Water
191,000 miles of rivers and streams
15 major river basins
13
Texas has wide, shallow prairie rivers
14
and clear, spring-fed streams creating pristine
habitats for unique species.
15
Slow-moving water in bayous sustain bottomland
hardwood forests.
16
Surface water flows towards the Gulf of Mexico.
17
Rivers deliver important nutrients and sediment
to coastal wetlands.
18
Our coastal wetlands buffer our coast from storms
19
and serve as nurseries for our seafood,
including shrimp, crabs and sportfish.
20
Coastal wetlands also provide habitat for both
migrating and resident birds.
21
Texans throughout history have shared water
resources with wildlife.
22
As populations grew, the demand for fresh water
grew.
23
People built dams to control flooding and corral
a steady supply of freshwater.
24
Today, virtually all of Texas 1.7 million acres
of lakes are man-made.
Caddo Lake is Texas only naturally-created lake
25
These reservoirs provide drinking water to about
half the state.
26
They provide opportunities for industry,
development, tourism and recreation.
27
Reservoirs and other water demands upstream can
alter life in wetlands.
28
In addition to altering water flow, Texas'
population is expected to double between 2000 and
2050.
29
Sharing water with each other and wildlife is an
unfolding challenge facing future Texans.
