Water Resources
The 2014 National Climate Assessment provides background information to help communities, water utilities, resource managers, and food and energy producers prepare for a changing climate. Given a need to develop resilience strategies based on an uncertain future, many experts look to past climate extremes for information to help guide and constrain decision-making. Information resources that may be helpful to provide characterization of the past and insight into the future include:
National Water Information System
National Water Information System
NWIS provides access to water-resources data collected at approximately 1.5 million sites in all 50 States, the District of Columbia, Puerto Rico, the Virgin Islands, Guam, American Samoa and the Commonwealth of the Northern Mariana Islands.The USGS investigates the occurrence, quantity, quality, distribution, and movement of surface and underground waters and disseminates the data to the public, State and local governments, public and private utilities, and other Federal agencies involved with managing our water resources.
National Weather Service Advanced Hydrologic Prediction Service
National Weather Service Advanced Hydrologic Prediction Service
AHPS is a web-based suite of accurate and information-rich forecast products. They display the magnitude and uncertainty of occurrence of floods or droughts, from hours to days and months, in advance. These graphical products are useful information and planning tools for many economic and emergency managers. These new products will enable government agencies, private institutions, and individuals to make more informed decisions about risk based policies and actions to mitigate the dangers posed by floods and droughts.
National Ground-Water Monitoring Network
National Ground-Water Monitoring Network
The NGWMN Data Portal provides access to groundwater data from multiple, dispersed databases in a web-based mapping application. The portal contains current and historical data including water levels, water quality, lithology, and well construction.
Water Quality Portal
The Water Quality Portal (WQP) is a cooperative service sponsored by the United States Geological Survey (USGS), the Environmental Protection Agency (EPA), and the National Water Quality Monitoring Council (NWQMC). It serves data collected by over 400 state, federal, tribal, and local agencies.
Downscaled CMIP3 and CMIP5 Climate and Hydrology Projections
Downscaled CMIP3 and CMIP5 Climate and Hydrology Projections
“Downscaled” (finer-resolution) versions of monthly and daily temperature and precipitation from most of the GCM simulations in the PCMDI CMIP3 and CMIP5 archives, for CONUS, using two downscaling methods. In addition, derived simulations of surface hydrology are provided.
National Climatic Data Center Climate Data Online
National Climatic Data Center Climate Data Online
Climate Data Online (CDO) provides free access to NCDC’s archive of historical weather and climate data in addition to station history information. These data include quality controlled daily, monthly, seasonal, and yearly measurements of temperature, precipitation, wind, and degree days as well as radar data and 30-year Climate Normals.
USDA FS Climate Change Resource Center
USDA FS Climate Change Resource Center
The Climate Change Resource Center (CCRC) is a web-based, national resource that connects land managers and decisionmakers with useable science to address climate change in planning and application.
NASA Hydrology Data and Information Services Center
NASA Hydrology Data and Information Services Center
The Hydrology DISC supports data products generated by Goddard Earth Sciences Data and Information Services Center Hydrological Sciences Branch. Data products from the North America Land Data Assimilation System (NLDAS) and the Global Land Data Assimilation System (GLDAS) can be accessed through several interfaces. NLDAS and GLDAS systems integrate data from multiple space-based Earth observing systems using advanced land surface modeling and assimilation techniques. These products support weather and climate forecast experiments, water resources applications, and water and energy cycle research.
Global Lake Temperature Collaboration
Global Lake Temperature Collaboration
The Global Lake Temperature Collaboration database is a compilation of lake summer surface water temperatures from 235 lakes around the world over a 25-year period.
Forced Evaporation from Water Surface
Forced Evaporation from Water Surface
The Forced Evaporation from Water Surface (FEWS) model estimates forced evaporation – the evaporation from surface waters caused by heat from cooling systems at thermoelectric power plants. The FEWS model provided estimates of consumption at approximately 400 power plants in the U.S. for 2010. Based on FEWS, withdrawal and consumption of water by thermoelectric power plants in the United States for 2010 are described in the associated report, which can be accessed at http://pubs.usgs.gov/sir/2013/5188/
Groundwater depletion in the United States (1900−2008)
Groundwater depletion in the United States (1900−2008)
A natural consequence of groundwater withdrawals is the removal of water from subsurface storage, but the overall rates and magnitude of groundwater depletion in the United States are not well characterized. This study evaluates long-term cumulative depletion volumes in 40 separate aquifers or areas and one land use category in the United States, bringing together information from the literature and from new analyses. Depletion is directly calculated using calibrated groundwater models, analytical approaches, or volumetric budget analyses for multiple aquifer systems. Estimated groundwater depletion in the United States during 1900–2008 totals approximately 1,000 cubic kilometers (km3). Furthermore, the rate of groundwater depletion has increased markedly since about 1950, with maximum rates occurring during the most recent period (2000–2008) when the depletion rate averaged almost 25 km3 per year (compared to 9.2 km3 per year averaged over the 1900–2008 timeframe).

California drought, visualized with open data
California drought, visualized with open data
The State of California is experiencing one of the most severe droughts on record, which has implications for citizens of California and beyond. Many State, Federal, and Tribal agencies make routine observations of the water cycle. This website graphically visualizes these data to help understand the effect of drought on rivers, streams, lakes, and reservoirs. Below, learn more about water use and changes in the water cycle due to the current drought in California. The data presented here are drawn from free and publicly accessible sources. In addition, the analytical, graphical, and software tools used are open-source and available for public re-use.
