Maia Dean, our amazing Community Engagement manager will be retiring from CBWCD effective today, May 29th
Maia began working for the Chino Basin Water Conservation District in July 2019. During her tenure, she's lead the creation of award-winning projects, established high-quality standards for the District's community events and our K-12th grade field trip program, and helped to significantly increase the Waterwise Community Center's name recognition for people across the region. She's acted as a leader, a mentor, and an advocate for not just her own team, but for every member of staff at the District.
Her excellence in communication, her resilience in the face of unexpected challenges, and her positive presence throughout it all will be missed by all of us here.
Thank you Maia, for all of your hard work. We hope you enjoy your future adventures during your retirement.
⭐ Congratulations! ⭐
On a recent tour of our watershed, we saw snowmelt making its way down the San Antonio Creek Channel, and we decided to give you a quick look at how we capture this snowmelt, along with stormwater, and put it to use by storing it in the ground
Using the concrete channels that have replaced natural creeks and streams, we channel snowmelt, from local mountains like Mount Baldy, and stormwater runoff from local streets into a set of recharge basins, which are also called percolation basins.
How does the water get into these basins? Using tools like grates, spillways, and inflatable dams, the water can be diverted to flow into these basins. The basins look like giant holes in the ground and each basin has porous soil, meaning that water that ends up here can soak through the soil quickly.
This water that soaks into the ground can then make its way even deeper into the ground and become part of the Chino Groundwater Basin, an area underground where water is stored between rocks, sand, gravel, and silt located beneath our feet.
The Chino Groundwater Basin has been used for many years, and originally supplied farmers and ranchers with precious water for their dairy cow, grapes, and citrus crops. Today it’s actively managed by local water agencies and still supplies water for residents in several cities.
If you would like to see a more in-depth look at where water goes, let us know in the comments or visit us at cbwcd.org/our-water/

🐝We’re buzzing with excitement over World Bee Day! 🐝
California hosts a diverse range of native bees that maintain and pollinate our native plant communities, sometimes even better than honeybees! 🌼 You may have seen some of the iconic Bumblebees that weigh down flower stems while pollinating, or Leafcutter bees that take circular pieces from native plant species for their nest, or even a Sweat bee glimmering in the sunlight as it zooms past. 🐝 Each and every one of these wonderful species depend on CA native plants and we can help them thrive by adding native plants to our gardens!
Come by the Waterwise Community Center to see our native bee-friendly waterwise garden and see how you can make the change yourself. 🌱
