Take the challenge

Experiment shows you how watersheds work

A watershed is an area of land that catches rain and then drains into a body of water like a river. Here is how you can build your own watershed:

1. Scrunch up newspaper into balls.

2. In a large container create a newspaper landscape that has at least one high point and several rolling hills. Try to create a lagoon at the bottom on one side. Be creative.

3. Place a kitchen trash bag over the paper allowing the plastic to mold over the newspaper and outside of the container.

4. Using a small sprayer filled with blue colored water to create rain. The sprayer will simulate a rain cloud that moves over the landscape. Slowly pour the rain as you move the watering can across the bin. Pay close attention to where the rainwater goes.

The Delta Flows with History

The Sacramento-San Joaquin Delta, also known as the California Delta, is the largest estuary on the western Pacific coast. It consists of 738,000 acres interlaced with hundreds of miles of waterways. The Delta is a network of rivers, tributaries and sloughs originally used by miners and settlers during the Gold rush. It is one of the few inverted river deltas, funneling water toward San Francisco bay. The Delta provides much of the water for California’s agriculture industry, the world’s third largest agriculture base. Two-thirds of the state’s drinking water flows through the Delta. Much of its land is below sea level and relies on nearly 1,100 miles of levees for flood control.
