West's Drought Threatens Small Towns More Than Cities

Smaller communities in the West are facing heightened risks from the ongoing drought crisis compared to larger metropolitan areas. These towns often depend entirely on a single water source and lack the extensive backup infrastructure that cities have developed over decades. The cost of developing alternative water supplies presents a significant barrier for communities with smaller customer bases.

Page, Arizona, a city of approximately 7,500 residents, draws its municipal water directly from Lake Powell, making it particularly vulnerable. Similar concerns exist for LeChee, a Navajo Nation community near Page, which relies on the same water network. While infrastructure upgrades have been completed to allow water access at lower elevations, these communities remain heavily dependent on the reservoir.

Boulder City, Nevada, also faces challenges as it relies solely on Lake Mead and does not return treated water to the reservoir, missing out on return-flow credits. Henderson and North Las Vegas, while part of the broader Las Vegas water system, are also significantly linked to the health of Lake Mead and its delivery infrastructure.

In contrast, major cities like Phoenix have diversified water sources including rivers, groundwater, and recycled water. San Diego has invested in desalination and recycling, while Las Vegas has built robust infrastructure for water withdrawal and employs significant water recycling. Tucson stores Colorado River water underground for later use.

Experts note that while solutions like advanced water purification and conservation are available, they come at an increased cost to residents. Cooperation between cities and strategic water management are crucial for strengthening resilience, though the era of cheap water is ending in the West.
