Western Water Supply refers to the systems and resources used to provide water in the western regions of the United States. This area often faces challenges such as drought and limited natural water sources, making efficient management crucial. Key sources include rivers, lakes, and groundwater, which are regulated by various laws and agreements. To address water scarcity, many states implement conservation practices and infrastructure projects, such as reservoirs and aqueducts. Organizations like the Bureau of Reclamation and U.S. Geological Survey play vital roles in monitoring and managing water resources to ensure sustainable supply for agriculture, industry, and residential use.
