The Mojave Desert’s primary source of water is underground aquifers.

In the Mojave Desert, water is scarce due to low rainfall and extreme dryness, so the primary source of water is underground aquifers. These aquifers are vast natural reservoirs located deep beneath the surface, storing water that is essential for both the desert ecosystem and human use. Wells are used to extract water from these underground sources for agricultural irrigation, drinking, and other needs. As surface water is minimal, the reliance on groundwater makes aquifers a critical resource in sustaining life in the arid Mojave Desert.
