Average annual precipitation in the Basin and Range Province is typically less than 10 inches.

This low level of precipitation contributes to the region's arid to semi-arid climate, characterized by dry conditions and limited water resources. The distribution of rainfall is uneven, with most precipitation occurring during the winter months in the form of snow in the higher elevations. The valleys, however, remain largely dry, which affects the vegetation and wildlife that can thrive in this environment. The scarcity of water shapes the landscape, influencing features such as intermittent lakes and salt flats, and poses challenges for agriculture and other human activities in the region.
