John Ellis

Biography

John Ellis is currently a Supervisory Hydrologist with the Texas Water Science Center. He began his USGS career in 2014 at the Oklahoma Water Science Center leading a hydrologic investigation of the Canadian River alluvial aquifer in cooperation with the Oklahoma Water Resources Board. John’s subsequent projects included the North Fork and Rush Springs aquifer studies focused on integrated surface water and groundwater resources. These projects included constructing the aquifer hydrogeologic framework, determining hydraulic properties, and running modeling simulations. His projects also included modeling the Washita River alluvial aquifer and evaluating the impacts of future climate variability on aquifer and reservoir storage.

In 2019, John moved to the Texas Water Science Center to serve as the Gulf Coast Branch Studies Chief. In this capacity, he works with a variety of cooperators to investigate issues related to water quality, land subsidence, and groundwater level changes. John holds a M.S. in Hydrogeology from The University of Alabama, a M.S. in Environmental Science from Hardin-Simmons University, and a B.S. in Geology from The University of Texas at Dallas.
