High Plains Aquifer 1935 Groundwater Levels

A large imbalance between recharge and water withdrawal has caused vital regions of the High Plains Aquifer (HPA) to experience significant declines in storage. A new predevelopment map coupled with a synthesis of annual water levels demonstrates that aquifer storage has declined. This raster dataset gives the 1935 groundwater levels in the HPA. This dataset, produced using methods described in Haacker, E. M., Kendall, A. D., & Hyndman, D. W. (2015), is part of a collection of raster datasets that give HPA groundwater levels over time.
