Water in Lake Mead - the U.S.' largest reservoir - is at its lowest level since 1937 when the reservoir was filled for the first time. At just 27% capacity, NASA images offer a stark illustration of climate change and a long-term drought that may be the worst in the U.S. West in 12 centuries.

WWAO is hosting a session at the 2022 American Geophysical Union Fall Meeting this December, jointly with NASA's Water Resources Program. Our session looks at how to improve water management using satellite Earth observations. We invite you to join us!

The 2022 National Water Use Data Workshop will focus on improving water-data management and sharing. The event is led by WWAO collaborators including the Western States Water Council Water Information Management Systems Group, U.S. Geological Survey, Interstate Council on Water Policy, and Internet of Water.

Images from Lake Oroville and Lake Shasta compiled by the state show ‘a shocking drop in water levels’ compared to years past. California, like much of the U.S. West can expect a searing, dry summer ahead.

Communities in the Cheat River watershed in West Virginia face frequent flooding, which threatens to reverse years of restoration work aimed at cleaning up pollution from mining. NASA has partnered with a local non-profit to help build resilience to future floods.

How much water is in mountain snowpack? That’s a question science has been attempting to solve for decades. Finally, NASA-developed technology provides an accurate answer, using a cutting-edge airborne sensor system and sophisticated software that also predicts when snow will melt.

NASA has co-launched a new modeling framework for assessing water use and estimating crop yields at regional levels. GEO-CropSim integrates Earth observations into crop models to help decision makers manage crop production while analyzing water use.

OpenET is a satellite-based tool that supplies critical information on water use in 17 western U.S. states. It will help farmers and water managers better understand water use and water lost through evapotranspiration.

In seasons when water is scarce, tools powered by NASA data can help farmers decide where to allocate water and nutrients for irrigation and fertilizer.

WWAO is hosting a session at the American Meteorological Society's 102nd Annual Meeting in January 2022. We invite you to join our discussion on building water solutions that harness satellite data to address decision-maker needs.
