Historic
drought causes big drop in Texas portion of Ogallala aquifer

The
historic Texas drought caused the Ogallala Aquifer to experience its
largest decline in 25 years across a large swath of the Texas
Panhandle, new numbers from a water district show.
The
16-county High Plains Underground Water Conservation District
reported this week that its monitoring wells showed an average
decline last year of 2.56 feet — the third-largest in the
district’s 61-year history, and three times the average rate over
the past decade. Farmers pumped more water during the drought to
compensate for the lack of rainfall, which was about two-thirds less
than normal last year in Lubbock and Amarillo.
Further
north in the Panhandle, along the state's border with Oklahoma, a
second water district also registered large declines in the Ogallala.
Steve Walthour, the general manager of the eight-county North Plains
Groundwater Conservation District, calculated on Monday that the
average drop in the Ogallala reached 2.9 feet last year.
"We’ve
seen some pretty heavy declines," Walthour said, noting that the
west side of his district got hit especially hard.
Given
the catastrophic nature of the drought, which was the most intense in
recorded state history, some farmers said things could have been
worse.
“You
never want to pull that much down, but under the circumstances I
think we’re probably coming out pretty well,” said Tommy Fondren,
who rents out his land in Crosby County for cotton farming.
Brad
Heffington, a cotton farmer based in Lamb County, pointed out that
the Ogallala in the High Plains Underground Water District was
essentially stable in 2010, a rainy year that allowed for some
replenishing of the aquifer. Some of the counties with larger
declines had large amounts of groundwater, he said — and farmers
were clearly making use of it, judging from the drops.
One
observation well in Floyd County recorded a decline of more than 25
feet, according to the High Plains water district.
Heffington,
who is also the chairman of the group Plains Cotton Growers, said
that farmers were doing their best to conserve the resource. But “the
bottom line is, it’s a finite resource and we’re mining it,” he
said. His own farm experienced declines of up to two feet last year,
and the place remains exceptionally dry, with less than 5 inches of
rain since July 3, 2010. […]
As
for this year, farmers say that spring rains have helped, but most of
the Panhandle remains in moderate drought, or worse. Fondren is
holding out hope for showers soon. "We’re going to go back to
pumping pretty hard again if we don’t get some rain," he said.
