The Middle Trinity Aquifer of Hays County: New Data, New Models, and New Management

Brian B. Hunt, P.G. and Brian A. Smith, Ph.D., P.G.

Barton Springs/Edwards Aquifer Conservation District

 

Introduction

The Middle Trinity Aquifer is an important water supply of central Texas and provides baseflows to streams via springs that sustain ecosystems and ultimately recharges the Edwards Aquifer. Increased demand for groundwater in central Hays County is prompting studies to evaluate the availability and sustainability of groundwater in the Middle Trinity Aquifers of central Texas.  Previous conceptual models in Hays County and current numerical models of the Middle Trinity are inadequate to address these key issues. Texas law provides groundwater conservation districts (GCD) as the only regulatory mechanisms to avoid negative impacts from the effects of high rates of pumping. However, the challenge for a GCD is to allow sustainable use of groundwater in a complex hydrogeologic system with Texas’ legal frameworks such as the Rule of Capture and other legal precedents.

This talk will describe our new conceptual model of the Middle Trinity Aquifer by focusing on two key areas that highlight the contrasting complex hydrogeology and issues related to pumping and their negative effects. The talk will conclude with some of the new management strategies of a GCD that could be implemented to address the effects of pumping.
