Groundwater Sources
Table 1.7 lists the 2011 groundwater pumping by county and aquifer for Region C (6). (Note that the
pumping totals do not match use totals given in Table 1.4. The Texas Water Development Board supplied
both sets of data. The discrepancy may be due to water that is pumped in one county and used in another.)
The Trinity aquifer is by far the largest source of groundwater in Region C, providing 41 percent of the
total groundwater pumped in 2011. (The Trinity aquifer is sometimes called the Trinity Sands and includes
the Antlers, Twin Mountain, Glen Rose, and Paluxy formations (6).) The Woodbine and Carrizo-Wilcox
aquifers provided 20.8 and 6.6 percent of the year 2011 totals, respectively. The remaining 31 percent
came from the Nacatoch, Queen City, Blossom, Unknown/Other aquifers, and undifferentiated aquifers.
The counties in which there are known to be several locally undifferentiated formations are Fannin (Red
River Alluvium), Jack, and Parker. There may be other counties in which this is the case, but it is believed
that the large 2011 use numbers from the unknown, other, and undifferentiated aquifers are likely to be2016 Region C Water Plan
