Rivers and Water Management in the Southwest

Abstract

In the Southwest US, rapid population growth is intensifying competition between human water demands and the ecological needs of rivers and wetlands. These ecosystems, though small in area, support rich biodiversity and provide vital services to people. Historically, water management has prioritized sectors like agriculture and urban development, often excluding environmental considerations. As a result, many rivers have become degraded due to damming, diversions, and groundwater pumping. Advances in river science now offer tools to define ecological water needs and guide sustainable management. By integrating hydrology, ecology, and policy, communities can re-operate dams, adjust diversions, and plan development to preserve ecosystem function. Groundwater use, often overlooked, directly impacts stream health, making spatial awareness and legal reforms essential. Ultimately, balancing growth with ecological sustainability requires informed choices, interdisciplinary collaboration, and proactive governance.
