Did you know that threatened and endangered species of fish in the San Lorenzo River rely on the same water that you do? The more water you use, the less there is for these critical species of fish. There are so many things you can do for a cleaner, healthier San Lorenzo River. Complete this activity to learn 10 different ways that you can help your river!

Activity Overview

In this activity, you can review the different ways that you can make a difference for the San Lorenzo River. You can read each one and think about whether or not it is something you already do, or might consider doing in the future. We encourage you to draw the activity, either in the space on the worksheet or wherever you might like. In the picture, you can draw what a clean and healthy river looks like, and the action that you want to take to help protect the environment around you!


Every day, we rely on and impact the San Lorenzo River. We rely on the river for drinking water. Did you know that two-thirds of the drinking water for Santa Cruz City Water customers comes from the San Lorenzo River watershed? We also impact the San Lorenzo River as pollution leaves your property and enters nearby waterways. There are so many ways you can act now to help your river. Check out this activity to learn more.
