DATA

The following interesting and useful data will be updated as soon as it becomes available.   

	Water Levels
	Water Quality
	Historic Rainfall
	Groundwater Availability Models

Water Levels

The Texas Water Development Board already monitors approximately 23 wells in Fayette County on an annual basis for water levels.  The District plans to add more wells to the monitoring network in the near future.   Watch for those water level readings, coming soon!

Water Quality

The District plans to install a water testing laboratory in the District Office, in order to offer free water quality testing to Fayette County residents.  Although the lab will not be an accredited facility, the information will be very useful to household water users as well as agricultural users.

Historic Rainfall

For actual rainfall figures for the three major cities in Fayette County, La Grange, Flatonia, and Schulenburg, go to Appendix B of the District's Management Plan.

Groundwater Availability Model

The Texas Water Development is in the process of developing state of the art, publicly available numerical groundwater flow models to provide reliable information on groundwater availability in Texas. 

A  numerical groundwater flow model is the mathematical representation of an aquifer in a computer.   Using the basic laws of physics that govern groundwater flow, we instruct the computer to consider the physical boundaries of the aquifer, recharge, pumping, interaction with rivers, or other phenomenon to model the behavior of the aquifer over time.   These models can be used to make predictions of how water levels might change in the future in response to changes in pumping or climate.

Groundwater availability models (GAMs) are planned for the two major aquifers in Fayette County, the Carrizo Wilcox and the Gulf Coast, as well as two of the minor aquifers: the Sparta and Queen City.

Models have been completed for the central and southern portions of the Carrizo Wilcox.  A model for the central portion of the Gulf Coast aquifer is currently under review by TWDB and should be completed by the summer of 2004.  

Work started in January 2003 on models of the Sparta and Queen City aquifers, and should be ready for review by October 2004.
