The Austin Discovery School in far East Austin sits on the line between two watersheds – Elk Creek and the Colorado River.
That means rain falling on the side of the Elk Creek watershed will trickle toward Elk Creek, while rain falling on the Colorado River side will trickle toward the Colorado River. But, that's only if the rain is absorbed into the soil instead of run off into storm drains.
Today’s experiment shows what happens when rain hits different types of ground.
Rain that falls on concrete or plain dirt will run off quickly, and very little water will be absorbed into the soil.
Lawn grass, however, slows down how quickly the water runs off, allowing more to be absorbed into the watershed.
Native plants and grasses work the best in helping rain soak into the ground because they have deep roots.
