That’s the Tuolumne in My Tap!

That’s the Tuolumne in My Tap  is Tuolumne River Trust’s Bay Area elementary school education program that teaches 4th and 5th grade students where their water comes from and why and how to conserve it.  We teach thousands of Bay Area students each year about the animals and communities that depend on the Tuolumne River, the current threats the River faces, and the things they can do to help protect our water supplies. Our goals are to:

  • Educate students about the source of their tap water, the Tuolumne River;
  • Create a life-long commitment to the stewardship of the Tuolumne watershed and the environment; and
  • Inspire students and their parents, teachers, and school administrators to create positive changes in their water usage habits.

Our free presentation includes a classroom visit with an interactive presentation and a hands-on water activity.  It aligns with several California Next Generation Science Standards for 4th, 5th, and 7th grade.  Since 2009, our Bay Area education program has reached over 40,000 students and hosted more than fifty field trips and service learning projects.

To help students and members of their communities fully realize the value of protecting their local watersheds, we also coordinate a series of community service projects during which students work alongside positive adult role models. Projects include local creek cleanups, native garden planting, and schoolyard water conservation projects such as drought-tolerant landscaping and rainwater catchment systems. Through partnerships with other organizations, we also take students on field trips throughout the Bay Area and occasionally to the Tuolumne River itself.

I want to help the animals out by trying to conserve water at my house and swim club. A couple ways I want to help out is that I don’t want to take as long showers as before, turning water off when I’m brushing my teeth, and not running the water so long. I told my parents about everything you told us, and they were amazed. My dad told me that he had no idea that his water was coming from the Tuolumne River. I also told my sister that half her body was Tuolumne River water.
