World Water Day is March 22, and to mark the occasion the Foundation is offering a special 20 percent discount on our beautiful poster-size maps, layperson’s guides and other water publications.

Use the promo code WORLDWATERDAY when checking out of our online shopping store.

Our Colorado River Basin map explores the many water supply uses – and challenges – along the “Lifeline of the Southwest.” We also have Layperson’s Guides to the Colorado River and the Colorado River Delta.

Our California Water Map highlights the dams, reservoirs, canals, rivers, lakes and other water bodies throughout the state and shows how water moves through California. Another recently updated map is the California Groundwater Map, which illustrates how groundwater works, the locations of groundwater basins around the state and the challenges from overuse.

Both maps also come in special bundles with their companion layperson’s guide. Explore the full array of maps, layperson’s guides and other publications on our website, www.watereducation.org/maps-publications.

Use promo code WORLDWATERDAY to get your discount. This offer is for one day only – Thursday, March 22.
