"The purpose of this report is to describe the water quality of the Blaine Aquifer, particularly as compared with public drinking water standards, and to analyze, if possible, any changes in water quality over time."

"This report is an update to the Texas Water Development Board (TWDB) Report 345, Major and Minor Aquifers of Texas, published in 1995 and coauthored by John B. Ashworth and Janie Hopkins."

This report describes updates to the earlier developed groundwater availability model for the Hill Country portion of the Trinity Aquifer System, "by (1) adding the Lower Trinity Aquifer as another layer to the model, (2) revising the spatial distribution of parameters, such as recharge and pumping, and (3) calibrating the steady-state water level and river discharge conditions for 1980 and historical transient water level and discharge conditions for 1987 through 1997" (p. 1).

This report examines the median water level changes in the state's major and minor aquifers, and describes where the largest declines and increases were within an aquifer and presents regional trends.

This report analyzes data on irrigation water use by crop type collected from 1999-2007 in the Panhandle, North Plain, Mesa, Hudspeth, Gateway, Rolling Plains, Coastal Bend, and High Plains groundwater conservation districts and the Lower Neches Valley Authority.
