Logos for Climate and Hydrology Projections PartnersReclamation and Partners Release New Hydrologic Projections for Contiguous United States - The Bureau of Reclamation has released new hydrologic projections that will help local water managers answer questions about future climate, stream flow and water resources. This new scientific data uses the updated World Climate Research Program climate projections that have been scaled to a finer resolution (downscaled) for water management decision support systems. "Reclamation is helping water managers prepare for the impacts of climate change with the release of this information, supporting the President's Climate Action Plan," Acting Reclamation Commissioner Lowell Pimley said. "Researchers and planners can use these future climate and hydrology projections to assess societal impacts and explore adaptation options." The new hydrology projections are available here. More information is available in the News Release

Cover of Interagency Report Published on Information Required for Short-Term Water Management DecisionsInteragency Report Published on Information Required for Short-Term Water Management Decisions - Adapting to future climate change impacts requires capabilities in hydroclimate monitoring, short-term prediction and application of such information to support contemporary water management decisions. These needs were identified in a report, "Short-Term Water Management Decisions: User Needs for Improved Climate, Weather, and Hydrologic Information," published by the Bureau of Reclamation and the U.S. Army Corps of Engineers with the National Oceanic and Atmospheric Administration.
