US Water Demand, Supply, and Allocation: Trends and Outlook

[PDF]

Given the overall importance of water, the long-term adequacy of water supply is a major national concern. This first in a series of Water Resources Outlook papers reviews future trends and uncertainties affecting water resources in the United States over the next 30 years. It discusses their impacts and implications for water demand, supply and allocation in specific geographic regions of the country. The implications include considerations on how the U.S. Federal government, states and localities might address the impacts of those trends. The review described in this paper, while not being a part of a congressional inquiry, has been initiated by IWR to support iterative strategic planning activities of the USACE Civil Works, including the development of strategic goals, objectives and strategies.
