Summary of Groundwater Conditions in Texas: Recent (2010-2011) and Historical Water Level Changes in the TWDB Online Recorder Network.

摘要

The Texas Water Development Board (TWDB), in partnership with its cooperators, continues to install and monitor automatic water level recorders in observation wells throughout the state. This report discusses the water level changes observed in 2011 in the 110 recorder wells in the states nine major aquifers and in the 16 recorder wells in eight minor and three undesignated aquifers. The report does not include data from recorders added to the network during 2011 or from wells equipped only with dataloggers. A relatively greater number of recorders exist in areas that have experienced water level declines, such as in the High Plains, and more recently in areas where groundwater use is increasing, such as in Central Texas. More than half of the 110 recorders discussed in this report are in wells in major aquifers: 26 are in wells in the Ogallala Aquifer and 33 are in wells in the Central Texas Trinity Aquifer.
