The vast farmlands of Pakistan — a country with an economy based on agriculture — rely on one of the largest continuous irrigation systems in the world. Farmers were once able to depend solely on rivers and man-made canals fed by glaciers and rain. But as population and urbanization boomed in recent decades, the country

RESTON, Va., Dec. 17, 2014—The U.S. Geological Survey has released a new report detailing changes of groundwater levels in the High Plains Aquifer. The report presents water-level change data in the aquifer for two separate periods: from 1950 – the time prior to significant groundwater irrigation development – to 2013, and 2011 to 2013.

PORTLAND, Ore., Oct. 16, 2014—The U.S. Geological Survey has developed a computer model that will help water managers understand the groundwater resources in the Willamette Basin and assist them in meeting current and future water demands. The study, done in cooperation with the Oregon Water Resources Department, builds on more than 10 years of data

Historical groundwater withdrawals have caused the loss of land-surface elevation, or subsidence, in the Houston-Galveston region. Loss of surface elevation is a concern as it may increase the potential for more intense flooding in the study area according to the latest annual report conducted by the U.S. Geological Survey.

The earth’s mighty shifting – which caused about $400 million in damage to Napa, Sonoma and Solano counties – also mysteriously forced groundwater to the surface and into several dry or nearly dry creeks and streams in the region. Torrents of water have been flowing down Wild Horse and Green Valley creeks and another unnamed waterway

Aquifers provide us freshwater that makes up for surface water lost from drought-depleted lakes, rivers, and reservoirs. We are drawing down these hidden, mostly nonrenewable groundwater supplies at unsustainable rates in the western United States and in several dry regions globally, threatening our future.
