High Plains/Ogallala Water Table Elevations Annual Estimates

This dataset consists of water table elevation estimates for the High Plains (Ogallala) Aquifer from 1935 to 2016, updated in 2017 using methods described in the following paper:

Haacker, E.M., Kendall, A.D. and Hyndman, D.W., 2016. Water level declines in the High Plains Aquifer: Predevelopment to resource senescence. Groundwater, 54(2), pp.231-242.

The dataset also includes derived aquifer boundaries and aquifer base elevation, which can be used to derive an estimate of saturated thickness. In addition, county-level information for average water tables, water in storage (saturated thickness x area x specific yield), and variance is included in an Excel file. Please see the ReadMe tab in the Excel file for more information.
