Participating Agencies

The Climate Change and Water Working Group (CCAWWG) strives to build "working-level" relationships across federal water management and science agencies. The primary goal of CCAWWG is to foster engineering and scientific collaborations in support of water management as climate changes. The participating federal agencies include:

Bureau of Reclamation Logo

Bureau of Reclamation (Reclamation)

The Bureau of Reclamation is the largest wholesaler of water in the country and the second largest producer of hydroelectric power in the western United States. Reclamation is a contemporary water management agency whose mission is to assist in meeting the increasing water demands of the West while protecting the environment and the public's investment in these structures. Reclamation places great emphasis on finding ways to bring together the variety of interests to address the competing needs for our nation's limited water resources.

U.S. Army Corps of Engineers Logo

U.S. Army Corps of Engineers (USACE)

The USACE Institute for Water Resources (IWR) provides analysis of emerging water resources trends and issues; state-of-the-art planning and hydrologic engineering methods, models and training; and national data management of results-oriented program and project information across Civil Works business lines. IWR’s Responses to Climate Change team represents USACE IWR on the CCAWWG.

NOAA logo

National Oceanic & Atmospheric Administration (NOAA)

NOAA’s Earth System Research Laboratory Physical Science’s Climate Analysis Branch strives to advance national capabilities to interpret the causes of observed climate variations and to apply this knowledge to improve climate models and forecasts and develop new climate products that better serve the needs of the public and decision-makers.

USGS logo

U.S. Geological Survey (USGS)

The sciences of hydrology, mathematics, chemistry, physics, ecology, biology, geology, and engineering are used to gain a fundamental understanding of the processes that affect the availability, movement, and quality of the Nation's water resources. Results of the USGS National Research Program’s long-term research investigations often lead to the development of new concepts, techniques, and approaches that are applicable not only to the solution of current water problems, but also to future issues that may affect the Nation's water resources.

EPA logo

Environmental Protection Agency (EPA)

EPA researchers are working to better understand climate change and how the effects will vary by region and over time, and how societies and the earth's environment will adapt to or cope with climate change. EPA's climate change research is focusing on those areas where EPA has the most to offer assessments of the consequences of climate change on air quality, water quality, human health and ecosystem health.

FEMA logo

Federal Emergency Management Agency (FEMA)

FEMA’s mission is to support our citizens and first responders to ensure that as a nation we work together to build, sustain, and improve our capability to prepare for, protect against, respond to, recover from, and mitigate all hazards.



NASA's role in characterizing, understanding and predicting climate variability and change is centered around providing the global scale observational data sets on the higher-inertia components of the climate system (oceans and ice), their forcings, and the interactions with the entire Earth system. Understanding these interactions goes beyond observations and includes developing and maintaining a modeling capability that allows for the effective use, interpretation, and application of the data. The ultimate objective is to enable predictions of change in climate on time scales ranging from seasonal to multi-decadal.




Climate change presents real threats to U.S. agricultural production, forest resources, and rural economies. These threats have significant implications not just for farmers, ranchers, and forest landowners, but for all Americans. Land managers across the country are already feeling the pressures of a changing climate and its effects on weather. As these risks continue and amplify, producers will be faced with the challenges of adapting.
