High Plains Aquifer

 [Image: High Plains aquifer location map.]

The High Plains aquifer consists of one or more hydraulically connected geologic units of late Tertiary or Quaternary age. It is underlain by bedrock units that range in age from Permian to Tertiary. The aquifer is divided into the northern High Plains, the central High Plains, and the southern High Plains regions. The northern High Plains aquifer underlies parts of Colorado, Kansas, Nebraska, South Dakota, and Wyoming. The central High Plains underlies parts of Colorado, Kansas, New Mexico, Oklahoma, and Texas. The southern High Plains aquifer underlies eastern New Mexico and northwestern Texas.

A regional Soil-Water-Balance model (see USGS Techniques and Methods report 6-A31) was constructed to estimate recharge for the 1940 through 1940 (predevelopment) and 2000 through 2009 time periods.

The data files listed below are supplemental to the following reports:

  • USGS Data Series report 777 titled 'Geodatabase Compilation of Hydrogeologic, Remote Sensing, and Water-Budget-Component Data for the High Plains Aquifer, 2011'
  • USGS Data Series report 543 titled 'Digital Map of Aquifer Boundary for the High Plains Aquifer in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming'
