From the Executive Summary: "The mission of the Bureau of Reclamation is to manage, develop, and protect water and related resources in an environmentally and economically sound manner in the interest of the American public. The weather and streamflow patterns that framed the development of water and power systems across the West are changing (Figure 1). As a result, Reclamation's basic mission objectives are at risk, including the ability to deliver needed quantities of water and power to agricultural, tribal, municipal, and industrial water users and water for environmental flows. Climate change also poses a threat to Reclamation's infrastructure, and along with it, the ability to continue to support customers and maintain ecosystems affected by Reclamation projects. Reclamation's response to the changing climate is essential to the sustainability of communities across the Western states and the National economy. […] The goals identified in this Strategy tier from key elements of the President's Climate Action Plan for the Nation (President's Plan), which identifies the continued development of sound science, water management planning and conservation, and increasing the resiliency of infrastructure as critical actions to prepare the United States for the impacts of climate change. The President's Plan highlights the importance of taking action now to maintain agricultural sustainability, manage drought, prepare for future floods, reduce wildfire risks and other objectives that have always been and are critical to Reclamation's mission and customers. This Strategy is also aligned with the Department of the Interior's (Interior) Climate Adaptation Policy (523 DM 1), which calls on the Bureaus to incorporate climate adaptation into agency decision making across mission areas."
