Walk around your neighborhood, a park, or even your backyard after it rains. Where does the water go? Does it soak into the soil, collect in puddles, or run off into storm drains? If you see a creek or river, check how high the water is after a rain compared to drier days. Think about where this water comes from and where it’s going. What happens when there isn’t enough rain? How do Austin’s water sources change during a drought?
Science Seed: Austin relies on the Colorado River and Highland Lakes for drinking water, but these sources shrink during droughts. Texas is known for cycles of dry and wet years, making water conservation essential. When rainfall is low, lake levels drop, and restrictions on water use help ensure there’s enough for everyone. Native plants, rain gardens, and water-saving habits—like turning off sprinklers during dry months—can help communities manage water more sustainably.

Assistive Technologies Available:
Step one
After it rains, go for a walk around your neighborhood, a park, or your backyard. Take note of where the water goes after it falls—does it soak into the soil, form puddles, or run off into storm drains?
Step two
If you have access to a creek or river, check how high the water is compared to a dry day. Can you see any changes in water levels after the rain?
Step three
Take notes about where you see water accumulating and how it moves through the environment. Create a map of your area and where the water is! Which surfaces are absorbing water, and which are causing runoff?
Step four
Reflect on where the rainwater comes from and where it goes. Does it eventually reach a body of water like a lake or river?
Step five
Think about what happens when there isn’t enough rain. How do water sources in Austin, like the Colorado River and Highland Lakes, change during a drought?
Step six
Once you’ve completed your walk and reflection, share your observations and understanding of Austin’s water flow and the importance of water conservation.
Step seven
