The primary method of water storage in the Mojave Desert is aquifers.

In the Mojave Desert, aquifers are the most vital source of water. These underground reservoirs store water that has filtered through soil and rock over time, and they provide a critical supply for human use, agriculture, and wildlife in an otherwise dry region. Due to the desert's low rainfall and the lack of surface water bodies like rivers or lakes, aquifers are essential for sustaining life. However, since aquifers recharge slowly, their management is crucial to avoid over-extraction, ensuring a steady water supply in this arid environment.
