Ron Green, a scientist at Southwest Research Institute in San Antonio, and his team of hydro-geologists are busy collecting data on and creating a lumped parameter model for the Uvalde Pool, a major reservoir of underground water centered over central Uvalde County and part of the Edwards Aquifer.

Though the project is relatively new, Green said their research in Uvalde has been ongoing for over 20 years.

“For over 20-plus years, we’ve been trying to quantify how much water goes in and out of the Uvalde Pool,” he said.

Over this time, his team has created a conceptualization of the Uvalde Pool river channels – with inflow from the Nueces River channel and outflow through the Knippa Gap.
