This summer’s Water and Natural Resources Tour included nearly 70 participants, from college students to retired farmers, and most with a firm background in water quality and quantity issues – except for me. As a 19-year-old undergrad student at the University of Nebraska-Lincoln (UNL), I set out with a vague awareness of the water issues facing Nebraska and neighboring state irrigators, but nothing to the extent that was presented on tour.

The High Plains Aquifer: Not an Underground Lake

January 16, 2015

The United States Geological Survey (USGS) released a report on the status of the High Plains Aquifer, the largest aquifer in North America and the aquifer that underlies eight states and supplies one-third of the groundwater pumped annually within the United States.

The report highlights that there are some locations in which the High Plains Aquifer has been severely depleted, with the water table dropping more than 150 feet in parts of Kansas and Texas. In other locations, the water levels have remained fairly stable, as is the case in Nebraska. Read More

Groundwater in the Mekong Delta

November 26, 2014

Saigon River

The Mekong River is one of the world’s largest rivers. Its headwaters are in China and it runs south through Myanmar, Laos, Thailand, Cambodia, and finally, Vietnam, where it empties into the sea through the Mekong Delta, a complex network of smaller rivers. Known as the “Nine Dragons Delta” in Vietnam, the Mekong Delta is home to almost 20 million people whose livelihoods depend on fisheries, aquaculture, and agriculture. Despite the abundance of surface water in the area, there is large-scale groundwater pumping for food production, industry, and household needs, and the number of co-existing and connected groundwater management challenges is staggering.

What happens in Neb., stays in Neb… and other things you didn’t know about the Ogallala Aquifer

For one thing, the aquifer that most think of — one of the world’s largest that underlies parts of eight U.S. states — is technically not the Ogallala Aquifer, but the High Plains Aquifer.

“That’s been a source of confusion,” said hydrogeologist Jim Goeke, professor emeritus at the University of Nebraska-Lincoln. “We use the names interchangeably, but they’re not the same. We have other productive aquifers in Nebraska in hydraulic connection that encompass the entire High Plains Aquifer.”

But the name aside, what bothers Goeke more is the common misinformation he encounters about aquifers, especially the High Plains. Read More
