High Plains Aquifer Water-Level Monitoring Study
Water-Level Data by Water Year (October 1 to September 30)

This web page provides files of water-level data used for the maps of water-level changes in the High Plains aquifer for the eight states that overly the aquifer. Only static water levels are used in the maps of water-level change. Static water levels generally are collected in winter or early spring, when irrigation wells typically are not pumping and water levels generally have recovered from pumping during the previous irrigation season, but a late fall water level is used if the fall measurement represents static conditions and it is the only available water level for the well. The files contents are tab-delimited; you will need to uncompress each file before you can use it.

Predevelopment (A static water-level measurements from 1930's to 1980's for each well, if available; for each well, this water-level measurement was made prior to substantial ground-water development in the well area.)
