The National Groundwater Association has announced that Peter G. McCornick, PhD, PE, D. WRE will give the keynote at NGWA’s Groundwater Week and the Irrigation Association’s 2016 Irrigation Show and Education Conference and is titled, Water for Food Security: Solutions for the Context. “Food and water security are two major interrelated challenges facing the world.
Background: Fresh water is an increasingly scarce resource in an increasingly populous and water-intensive world. Maintaining an adequate supply of fresh water both nationally and globally will be one of the largest challenges of the 21st century. Desalination of salty water – from both the ocean and the ground – represents a huge potential source of fresh water. The development of this resource requires a combination of geoscience, engineering, waste management, policy, and community outreach and participation.

The House Natural Resources Committee on Water, Power, and Oceans Subcommittee met to discuss conflicting proposals between the U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) on water release from the Shasta Dam.
Roughly 60 percent of global groundwater use is for irrigation; most of the rest is used in households and industry.1 Groundwater uses vary significantly by country, and partly depend on climate. In some countries with abundant rainfall, such as Indonesia and Thailand, irrigation needs are very low, so household water supply is the main use for groundwater.
The Senate Indian Affairs Committee held a hearing led by Chairman John Barrasso (R-WY) to discuss bills addressing contentious tribal water rights in Montana and Arizona (S. 3013 and S. 2959) and repealing obsolete laws relating to Native Americans (S. 2796).
The Lawrence Livermore National Laboratory, under the direction of the U.S. Department of Energy and using data from the U.S. Geological Survey, has produced flow charts showing the major sources and uses of water in every U.S. state in the year 2005.
The Nebraska Department of Natural Resources provides information about dams in the state in interactive map form. The map shows all dams more than 25 feet high or with a maximum storage capacity greater than 50 acre-feet.
Dams are color-coded according to the potential hazard they pose, with symbols designating existing dams, breached dams, and dams under construction. Specifications are available for each dam, including height, storage capacity, maximum discharge, surface area, and drainage area.
The U.S. Geological Survey's Streamer application allows users to explore where their surface water comes from and where it flows to. By clicking on any major stream or river, the user can trace it upstream to its source(s) or downstream to where it joins a larger river or empties into the ocean.
Groundwater use is highest in parts of the country with limited rainfall but high water needs, especially for irrigation. Most of these areas are in the western half of the country, where annual rainfall is typically much lower than in the East and where surface water supplies cannot meet the demand for water.
In 2015, groundwater provided 29% of the total freshwater used in the United States. However, eight states and at least one territory depended on groundwater for at least 50% of their freshwater supply:1
The U.S. Geological Survey's Texas Water Dashboard provides an instant, real-time picture of water and weather conditions in Texas. Information for streams, lakes, reservoirs, precipitation, and groundwater measurements are combined with weather and hazard conditions updated every minute, as well as recent precipitation totals and forecasts for next seven days.
